Ranking 5 Breakout Prospects: Jack Gurevitch
By Riley Thompson · Fri Feb 20 2026
In baseball scouting, a "breakout prospect" represents more than just untapped potential—it's a player standing on the precipice of significant development, armed with tools that suggest they could exceed current expectations and ascend organizational rankings. These are prospects who possess the raw ingredients for success but haven't yet fully demonstrated that ability in professional competition, often due to limited opportunity, physical projection, or the need for technical refinement. The five players below are ranked based on their long-term value. Over the next few weeks we will be ranking and highlighting groups of prospects that could breakout in 2026. Drawing from 80Grade's comprehensive prospect database, we've identified five players whose combination of physical tools, recent performance trends, and developmental trajectories position them as potential breakout candidates for 2026 and beyond. This group features both advanced college bats and raw international arms, representing the spectrum of developmental paths in modern player development. 1. Jack Gurevitch , 1B/OF, St. Louis Cardinals Physical Profile & Positional Flexibility: Gurevitch brings a versatile 6'0", 215-pound frame capable of handling both first base and corner outfield positions. Currently at Single-A Palm Beach, the 21-year-old left-handed hitter provides the Cardinals with organizational depth at multiple positions while his bat develops. His dual-position capability creates roster flexibility that organizations value, especially for prospects whose offensive profiles don't yet justify everyday roles. Offensive Tools: Gurevitch's above-average hit tool (55-grade) represents his primary calling card, suggesting he can make consistent contact and handle advanced pitching with proper plate discipline. His average power (50-grade) indicates developing strength that should produce 12-18 home runs annually at maturity, sufficient for a corner position if paired with solid batting averages. His below-average speed (45-grade) limits his baserunning impact but doesn't disqualify him from outfield duty given his other tools. Defensive Value: With below-average fielding grades (45) and average arm strength (50), Gurevitch profiles best at first base long-term, though he can handle left field in a pinch. His defensive limitations place maximum pressure on his bat to produce at levels that justify roster spots over more versatile defenders. Organizations will monitor whether his hit tool develops enough to carry below-average defensive value. Breakout Path: Gurevitch's 2026 breakout hinges on proving his hit tool translates to consistent production at High-A and beyond. If he can post .270+ batting averages while tapping into his power projection for 15-20 home runs, he profiles as a potential platoon first baseman or left fielder. His left-handed bat and contact-oriented approach give him value against right-handed pitching, potentially carving out a strong-side platoon role even if he never becomes an everyday player. The Cardinals will evaluate whether his hit tool justifies his defensive limitations or if organizational depth forces difficult roster decisions. 2. Ramon Marquez , RHP, Philadelphia Phillies Physical Profile & Development Stage: At 20 years old and pitching in the Florida Complex League, Marquez represents an early-stage developmental arm whose projection exceeds current performance. His 6'2", 182-pound frame suggests room for 15-20 pounds of functional strength as he matures, potentially adding velocity and durability to his arsenal. His youth and level indicate a 3-4 year timeline before major league consideration. Arsenal Evaluation: Marquez features an average fastball (50-grade) that should gain velocity with physical maturation and strength gains. His above-average changeup (55-grade) provides a foundation for attacking left-handed hitters and demonstrates advanced feel for his age. His slider grades as fringe-average (45), showing developing spin and bite but requiring refinement. His command sits at fringe-average (45), predictable for a 20-year-old in complex ball as he learns to repeat his delivery under competitive pressure. Development Focus: The Phillies will prioritize fastball velocity development through strength training and mechanical refinement, targeting 92-94 mph from his current baseline. His changeup already shows promise, giving him a legitimate out pitch if his fastball velocity improves. Slider development and command consistency represent his primary developmental hurdles, both addressing through repetition and coaching. Breakout Path: Marquez won't break out in 2026 in traditional terms, but his season will establish whether he profiles as a starter or reliever long-term. If his fastball velocity jumps 2-3 mph with maturity and his changeup remains a plus pitch, he could develop into a back-end starter whose pitchability compensates for average stuff. The Phillies will monitor his ability to throw strikes consistently and whether his slider develops into a usable third pitch. His changeup gives him a higher floor than many early-stage arms, creating potential for solid relief value even if his starting profile doesn't materialize. 3. Deniel Ortiz , C, St. Louis Cardinals Physical Profile & Positional Value: Ortiz brings a sturdy 6'1", 230-pound frame built for the rigors of catching. At 21 years old and playing at Single-A Peoria, he represents a bat-first catching prospect whose offensive potential could carry defensive limitations. His physical strength and right-handed bat provide power projection that separates him from defense-first receivers. Offensive Tools: Ortiz's above-average raw power (55-grade) represents his primary offensive weapon, suggesting 20-25 home run potential at maturity if he can make consistent contact. His below-average hit tool (45-grade) creates the classic power-over-hit profile common among young catching prospects who sell out for power at the expense of contact consistency. His below-average speed (40-grade) is standard for catchers, where running ability matters less than bat and glove. Defensive Evaluation: With below-average receiving grades (45) and above-average arm strength (55-grade), Ortiz profiles as a catch-and-throw specialist whose arm keeps the running game honest but whose framing and blocking need refinement. His 55-grade arm provides genuine defensive value in controlling basestealers, though his receiving mechanics require continued development to handle advanced pitching staffs. Breakout Path: Ortiz's breakout requires improving contact consistency while maintaining his power output. If he can reduce strikeouts and post .240 batting averages with 20+ home runs, he profiles as a potential backup catcher or strong-side platoon option whose power creates occasional lineup impact. His arm strength gives him defensive credibility that bat-only catching prospects lack, creating multiple pathways to the majors. The Cardinals will monitor whether his hit tool develops enough to support everyday consideration or if his power/arm combination profiles better in a reduced role. 4. Anthony Huezo , OF, Houston Astros Physical Profile & Elite Tools: Huezo's 6'2", 185-pound frame supports an explosive toolset headlined by plus-plus raw power (70-grade) that immediately captures attention. At 20 years old and playing at Single-A Fayetteville, this left-handed hitter represents one of the highest-ceiling prospects on this list, with premium power potential balanced against significant contact concerns. His above-average speed (55-grade), fielding (55), and plus arm strength (60) create genuine defensive value across all three outfield positions. Power Projection: The 70-grade raw power represents elite territory, suggesting 30-35 home run potential if Huezo can make consistent contact. Players with plus-plus power create lineup impact even with batting average limitations, as their ability to change games with one swing compensates for strikeout concerns. His left-handed bat and natural loft generate loud contact when he connects, the kind of exit velocity and launch angle combination that evaluators project for impact power. Hit Tool Concerns: Huezo's below-average hit tool (45-grade) represents the primary developmental question mark. Young power hitters often struggle with pitch recognition and swing decisions as they learn to balance power production with contact consistency. His current profile suggests significant strikeout rates as he refines his approach and learns to recognize breaking balls. The Astros will work on shortening his swing path, improving his two-strike approach, and teaching him to use the whole field rather than selling out for pull-side power. Defensive Value: His combination of above-average speed, fielding, and plus arm strength creates genuine defensive value that provides a safety net as his bat develops. He can play all three outfield positions credibly, with right field or center field the most likely landing spots depending on organizational needs. His defensive versatility gives him a higher floor than pure bat-first corner outfielders, creating potential utility value even if his hit tool never fully arrives. Breakout Path: Huezo's 2026 breakout requires demonstrating improved contact consistency while maintaining his elite power output. If he can reduce strikeouts to manageable levels (25-28% K rate) and post .230+ batting averages with 25-30 home runs in full-season ball, he forces his way into top-100 prospect consideration. His combination of elite power, speed, and defensive versatility creates multiple pathways to impact, from everyday center fielder to middle-of-the-order corner masher. The Astros will tolerate strikeouts if his power truly plays at plus-plus levels, but contact improvements determine whether he profiles as an impact regular or boom-or-bust slugger. His ceiling ranks among the highest in this entire series. 5. Freddy Contreras , RHP, Kansas City Royals Physical Profile & Age: At just 17 years old and pitching in the Dominican Summer League, Contreras represents pure projection. His 5'11", 178-pound frame suggests moderate physical development remaining, with room to add 15-20 pounds of functional strength. His switch-hitting designation in the data appears to be an error given his pitcher grades; he's a right-handed pitcher whose youth and level place him 5-6 years from major league consideration. Current Arsenal: Contreras features a plus fastball (60-grade) that plays well for his age and level, suggesting velocity could jump further with physical maturation. His above-average command (55-grade) represents his most advanced skill, indicating feel for the strike zone and delivery repeatability that many teenage pitchers lack. His average slider and curveball (both 50-grade) provide usable secondary options, while his fringe-average changeup (45) needs continued development to attack left-handed hitters effectively. Developmental Advantages: Teenage pitchers with plus fastballs and above-average command possess two of the three critical ingredients for starting pitcher success (the third being quality secondary pitches). Contreras's ability to throw strikes consistently at 17 suggests advanced pitching instincts and mechanical repeatability that coaching can build upon. His command gives him a higher floor than many teenage arms who rely purely on velocity without control. Projection Timeline: The Royals signed Contreras as an international free agent, betting on his fastball/command combination and physical projection. His development timeline extends well into the future, with 2026 likely spent in complex-level ball refining his breaking balls and building arm strength. Organizations monitor teenage DSL pitchers for arm health, mechanical consistency, and secondary pitch development; Contreras checks the command and fastball boxes, with breaking ball refinement his primary focus. Breakout Path: Contreras won't impact the majors in 2026, but his season will establish his developmental trajectory. If his fastball velocity maintains or improves as he adds strength, and his breaking balls develop into average-or-better offerings, he projects as a potential mid-rotation starter whose command and multiple pitches create consistent outs. His plus fastball and above-average command give him starter upside, while his age and level require patience from evaluators. The Royals will prioritize arm health, mechanical consistency, and changeup development as he advances through their system. His ranking reflects long-term starter potential rather than immediate impact, a bet on command and fastball quality translating to future success. Conclusion This group showcases diverse developmental paths and risk profiles. Gurevitch offers a polished college bat with positional versatility; Marquez brings changeup feel and starter projection; Ortiz combines catching scarcity with power potential; Huezo presents elite tools with significant swing-and-miss to overcome; and Contreras represents a teenage arm with plus velocity and advanced command. Each player offers distinct breakout potential, from Gurevitch's near-term utility value to Contreras requiring multiple years of development. For evaluators and dynasty league managers, these names merit attention as organizational assignments and development plans take shape for 2026.
