Broad Street Phaithful Prospect Weekly: Rincon's September Surge, DeMartini's Walk Rate Keeps Climbing
By Clint Rivera ·
Broad Street Phaithful Prospect Weekly covers the last 7 days of action for the Phillies farm system.
Rincon's September Power Binge Has Changed His Outlook
Bryan Rincon (AA, SS, Rank: 15) went 6-for-16 with three home runs, a double, 11 RBI, and four walks across 16 plate appearances this week, with just two strikeouts. That is a line that looks like a misprint from a player who entered 2026 projecting as a glove-first utility type with a 45 hit tool and 45 power grade. He is a defense-first shortstop whose value has always resided in an above-average arm, clean infield actions, and enough bat-to-ball discipline to stay in lineups. The three home runs this week are not a fluke in isolation, they are part of something that has been building for a month.
Over the last 30 days at Double-A Reading, Rincon is slashing .325/.481/.725 with nine home runs, five doubles, 22 RBI, 22 walks, and a 16.0 percent strikeout rate across 106 plate appearances. The strikeout rate in that window is the lowest sustained mark of his professional career, and the 20.8 percent walk rate is equally striking from a player who posted a .166/.292/.277 line across 411 plate appearances at High-A in 2025. His swing rate has held at 38.7 percent, the same disciplined profile he carried into the year, but the contact quality has shifted: a 80.3 percent contact rate over the last 30 days, paired with nine home runs, suggests better barrel efficiency rather than a mechanical overhaul. The season line at Double-A now sits at .267/.410/.517 with 26 home runs, 95 walks, and a 20.8 percent K rate across 534 plate appearances. For a utility projection with modest offensive grades, that is a serious body of work. The most honest read is still that his career arc skews toward a multi-position bench role with the glove carrying the profile, but September Rincon has given the organization real data points to reconsider where the offensive ceiling sits.
DeMartini's Patience Is the Story of His Double-A Season
Carson DeMartini (AA, 3B, Rank: 16) went 8-for-21 with a home run, two doubles, three RBI, six walks, and a hit-by-pitch across 21 plate appearances this week, striking out just twice. The walk total continues a pattern that has defined his 2026 season at Reading. He is a 45 hit, 55 power left-handed third baseman whose first run through Double-A in 2025 was genuinely rough: a .202/.291/.288 line across 292 plate appearances, with a 25.7 percent K rate that exposed real vulnerability to upper-level velocity and spin away. He came back this year and looked like a different hitter from the start.
Over his last 30 days at Double-A, DeMartini is slashing .362/.541/.667 with three home runs, eight doubles, two triples, 17 RBI, 26 walks, and an 18.4 percent strikeout rate across 98 plate appearances. His swing rate in that stretch has dropped to 33.0 percent, the most selective he has been as a professional, and while the contact rate at 69.8 percent is below average, the power output has been consistent enough that the approach is working. His season slash at Reading sits at .286/.421/.508 with nine home runs, 11 doubles, and a 18.3 percent BB rate across 235 plate appearances. The 2025 walk rate at Double-A was 9.6 percent; in 2026 it has nearly doubled. Some of that is selectivity, some of it is pitchers pitching around him more, but the result is real on-base production from a profile that looked like a genuine question mark twelve months ago. The projection still lands at a second-division regular with a floor of a bench role, and contact quality against premium arms remains the thing to watch as he faces better pitching. But the patience is not a mirage, and a full offseason with this approach in hand gives him something concrete to build on.
Quick Hits
Aroon Escobar (AA, 2B, Rank: 9) · went 6-for-17 with two home runs, two doubles, six RBI, two walks, and a hit-by-pitch this week. The power is real right now: over his last 30 days at Double-A he is slashing .269/.400/.538 with five home runs and a 13.7 percent walk rate across 95 plate appearances. A contact bat with a 40 power grade and a season slugging of .347 through most of the year, he has posted a .538 slugging mark over the past month. The season K rate has dropped to 16.2 percent and the strikeout rate in the last-30-day window matches it, suggesting the barrel efficiency and bat-to-ball skill are both trending in the right direction as the year closes.
Keaton Anthony (AAA, 1B, Rank: 32) · went 7-for-21 with a home run, two doubles, five RBI, and three walks across 21 plate appearances. His season at Triple-A Lehigh Valley sits at .282/.362/.462 with 11 home runs and a 10.7 percent BB rate across 318 plate appearances, a steady line for a 25-year-old first baseman who profiles as a 55 hit, 45 power up-down type. The last-30-day stretch at Triple-A is his best of the year: .302/.443/.556 with four home runs, 16 walks, and a 16.5 percent K rate across 79 plate appearances, with his swing rate dropping to 36.7 percent, well below his season average. He does not have a carrying power or speed tool, but the contact and approach keep producing.
Aidan Miller (AA, SS, Rank: 1) · returned from a back injury and went 3-for-15 with a double, two RBI, and five walks across 15 plate appearances in a limited week at Double-A. He is a 55 hit, 55 power everyday projection at third base, and the walk rate in that sample reflects the discipline that has defined his career at Reading. Over his last 30 days the BB rate sits at 24.0 percent across 25 plate appearances; the sample is small after time missed, but the approach has not wavered. Getting him back on the field and through these final weeks healthy is the only meaningful development item right now.
Dante Nori (AA, OF, Rank: 8) · managed just 2-for-16 with two RBI and three walks this week, a tough stretch for a player whose profile depends on contact and on-base skill to drive value. Over the last 30 days at Double-A he is batting .200 with a 15.7 percent BB rate across 89 plate appearances, a contact rate of 86.0 percent suggesting the swing-and-miss is not the issue. An everyday CF projection with a 65 speed grade and 60 fielding grade, his floor remains intact; the bat just has not shown up in September. He has 17 stolen bases on the season, and the defensive and baserunning value travel regardless of the week's results.
Gabriel Rincones Jr. (AAA, RF, Rank: 10) · went 3-for-29 with two home runs, four RBI, three walks, and seven strikeouts across 29 plate appearances, a rough week that reflects the broader tension in his profile. His 60 power grade is legitimate: six home runs at Triple-A this season and a .506 slugging mark over the last 30 days at Lehigh Valley. But the strikeout numbers have been a consistent drag since his MLB stint, where he posted a 32.6 percent K rate across 89 plate appearances with the Phillies earlier this year. His contact rate at Triple-A over the last 30 days sits at 68.9 percent with a 55.0 percent swing rate, the most aggressive stretch of his season. The power plays; the swing decisions against upper-level arms remain the conversation heading into the offseason.
Cody Bowker (AA, RHP, Rank: 18) · worked four innings this week, allowing two earned runs on two hits and three walks while striking out six and generating 12 swinging misses on 76 pitches. The strikeout rate and whiff total both reflect what makes him interesting: a 60-grade four-seamer with unusual ride and a 55-grade changeup that gives him a legitimate weapon against both sides of the plate. Over the last 30 days at Double-A the ERA is 4.24 across 23.1 innings with a 27.6 percent K rate and a 6.1 percent walk rate. Command has been the consistent variable; the 40-of-76 strikes thrown this week is a strike rate that will need to improve for the starting path to hold. A #5 starter projection with a bullpen floor, and the whiff generation keeps that ceiling in play.
Gage Wood (AA, RHP, Rank: 2) · logged 3.2 innings this week against 16 batters, allowing three earned runs on two hits and three walks while striking out four and generating five swinging misses on 78 pitches. The 34-of-78 strike rate reflects the command inconsistency that has been the recurring theme at Double-A. His season ERA sits at 4.72 across 68.2 innings at Reading, with a 33.1 percent K rate and 14 home runs allowed. The fastball sits 95-99 with genuine carry and the curveball is a legitimate out pitch, so the stuff is not the problem. Over the last 30 days the whiff rate is 35.8 percent and the K rate is 31.3 percent, both signs the arsenal is still missing bats. A #3 starter ceiling remains the honest read, but the command needs to tighten over a full season's workload before that projection stops feeling aspirational.
