Redbird Minor League Weekly: Rodriguez Keeps Rewriting the Script, Doyle's Last 30 Make the Case for St. Louis
By Caleb Hughes ·
Redbird Minor League Weekly covers the last 7 days of action for the Cardinals farm system.
The 19-Year-Old Backstop Who Won't Stop
Rainiel Rodriguez (AA, C, Rank: 1) went 10-for-24 with four doubles, a homer, and six RBI this week against Springfield arms, adding two hit-by-pitches and striking out just twice in 24 plate appearances. Those numbers are striking on their own, but the week fits into a month that has been genuinely hard to believe from a player his age at this level. Over his last 30 days, Rodriguez is slashing .389/.436/.711 with six home runs and 11 doubles across 101 plate appearances, posting a contact rate of 81.6 percent while swinging at 54.6 percent of pitches. He is being more aggressive than ever and making more contact than ever, which is the best-case version of what his offensive profile can offer. The combined season line sits at .310/.400/.534 with 19 home runs, 27 doubles, 68 RBI, and 49 walks against 89 strikeouts across 448 plate appearances at A+ and Double-A. He is 19 years old.
The profile has always centered on a 60 power tool paired with a hit tool that carries real contact feel even at an aggressive swing rate, and the last month has pushed those grades into uncomfortable territory because he is running ahead of them. The honest critique remains the defensive side: receiving and blocking behind the plate are still the least settled parts of the profile, and if those areas stall, the offensive bar he must clear to hold a catching role rises sharply. A 45 field grade and a mature body already limit the physical projection runway available to close those gaps. But none of that is slowing down what is happening at the plate right now. When a 19-year-old catcher is posting a .711 slugging percentage over a 22-game stretch at Double-A while maintaining an above-average walk rate, the conversation about his ceiling has to move. He came into the season graded as a second-division backstop; this month has made that look conservative.
The Last Month of Liam Doyle Changes the Perspective
The season ERA of 4.14 and 49 walks across 87 innings have made it easy to dismiss Liam Doyle (AA, LHP, Rank: 4) as a profile stuck between his stuff and his execution. Then you look at the last 30 days. Over five starts and 26 innings, Doyle owns a 1.38 ERA with 37 strikeouts, 11 walks, a homer allowed, and a WHIP of 0.88. His strike rate has climbed to 50.4 percent during that stretch, and his whiff rate sits at 36.2 percent, both the best marks he has posted in any extended run this season. This week's line was 5.0 innings, 1 hit, 1 earned run, 2 walks, and 9 strikeouts, continuing a stretch in which the pitch-mix is operating the way the scouting grades project it should. The 60-grade four-seamer is riding at 95-98 with carry toward the letters, and when the 60-grade slider is operating behind it with late bite, hitters are guessing rather than reacting. The 115 strikeouts in 87 innings for the season reflect what happens when those two pitches sync.
The central tension in his profile remains fastball command, and 49 walks through 20 starts is not a solved problem. The walk rate in the last month is still above where it needs to be, and the season homer total of 10 points to fastballs caught over the plate when location drifts. His delivery isn't the most fluid and that can generally make repeating it more difficult.
What this run does suggest is that his feel for sequencing within a start has sharpened: fewer big innings, better use of the changeup to keep right-handed hitters off the slider pattern, and cleaner fastball location to his arm side. He is a #3 starter projection with a 50 command grade that has some room to grow, and the last five starts look more like that projection than anything earlier in the season. If this version of Doyle is what the Cardinals get through the end of August, a late-2026 or early-2027 rotation conversation becomes difficult to avoid.
Quick Hits
Colton Ledbetter (AAA, OF, Rank: 35) · drove in 6 runs on 6 hits, including three home runs, in 23 plate appearances, adding three walks against seven strikeouts. The power surge caps a scorching month: over his last 30 days, he is slashing .365/.420/.622 with four homers and seven doubles across 81 plate appearances. His season line at Memphis (.267/.336/.435) had raised fair questions about whether his A-ball speed and gap production would play at Triple-A, but three home runs in a week against upper-level arms refreshes the conversation. He is a 55-speed outfielder with average power and enough on-base feel to profile as a useful bench bat; this month has been his best argument that the floor is higher than the season line suggests.
Chase Davis (AAA, LF, Rank: 31) · went 7-for-22 with a double, a homer, and 7 RBI this week against Memphis competition. The RBI total is the most eye-catching number; Davis has 40 on the season across 283 combined plate appearances. The power tool grades at 55 with elite documented exit velocity, but his last-30-day contact rate of 67.3 percent shows how much the strikeout risk can limit him when he is not in a hot stretch. He's a left-handed corner bat with a plus arm who needs barrel consistency to hold an everyday role; weeks like this one are why the Cardinals have been patient.
Sebastian Dos Santos (A, SS, Rank: 16) · walked six times against two strikeouts in 17 plate appearances, picking up three hits and driving in two runs. The walk total matters more than the hit total here. At Palm Beach this season, the 18-year-old switch-hitter owns a .383 walk rate and has drawn 34 free passes in 201 plate appearances, a level of plate discipline that is genuinely rare at his age and level. He projects to second base long-term with a 55 field grade and a fringy arm, and this week was a reminder that the approach is the carrying trait while the rest of the profile fills in.
Jack Gurevitch (AA, 1B, Rank: 20) · went 8-for-26 with a double and an RBI this week, adding two walks against seven strikeouts. The hit total is encouraging but the context cuts both ways: Gurevitch has a 60.3 percent swing rate and a 67.7 percent contact rate over the last 30 days at Double-A, a combination that points to real contact stress against upper-level velocity and spin. His season across all stops sits at .285/.368/.525 with 24 home runs, and the 55 hit tool with 55 power gives the profile genuine appeal at first base. The question is whether that contact rate holds up enough to let the power play consistently.
Hancel Rincon (AAA, RHP, Rank: 38) · was the week's most efficient pitcher, striking out 6 over 4.1 hitless, scoreless innings without issuing a walk. It extends a genuinely useful run: over his last 30 days, Rincon owns a 2.81 ERA across 16 innings with 25 strikeouts and a 0.88 WHIP, pushing his season ERA at Memphis to 3.93 through 68.2 innings. He is a quad-A projection with a 50 slider as the best weapon, but this month has him pitching like a guy worth a spot call whenever the Cardinals need length.
Daniel Eagen (AA, RHP, Rank: 12) · struck out 4 over 6.0 innings of one-run ball, allowing just 4 hits and 1 walk since joining Springfield after his acquisition from the Amarillo system. His last-30-day line at Double-A is a 2.45 ERA across 22 innings with 27 strikeouts, a 42.2 percent whiff rate, and a WHIP of 0.86, all significant steps forward from his full-season marks. A 55 curve and a 55 four-seamer give him two legitimate weapons, and the strikeout volume is real; the walk and homer rates across the full 99-inning sample are the things to watch as he settles in at Springfield.
Yhoiker Fajardo (AA, RHP, Rank: 24) · tossed 6.0 innings of one-run ball with 5 strikeouts and 2 walks in his third Double-A start. The 19-year-old's transition from A+ Peoria has gone smoothly so far: across five starts and 23.1 innings at Springfield this month, he owns a 3.47 ERA with 28 strikeouts, a 37 percent whiff rate, and a WHIP of 1.24. His sinker/slider foundation and average-to-above command grade for his age make the #4 starter projection feel grounded rather than aspirational.
Jurrangelo Cijntje (AAA, RHP, Rank: 9) · allowed 1 earned run on 4 hits over 4.0 innings with 4 strikeouts and 3 walks. The walk total continues to be the story: he has issued 16 free passes in his last five Triple-A starts across 24.1 innings, and the season ERA at Memphis sits at 5.72. The stuff is real and the 60-grade fastball and 55-grade cutter/slider combination give him a mid-rotation ceiling, but command at 45 has not ticked up at Triple-A the way the projection needs it to.
Joshua Báez (MLB, RF, Rank: 3) · was recalled to St. Louis on August 15 after posting a .256/.328/.573 line with 34 home runs and 21 steals across 461 Triple-A plate appearances. The Cardinals' top position prospect by rank, he accomplished an amazing feat, hitting 3 homers in his first three plate appearances. He's yet to homer since and has generally struggled after that first game. He's hitting .160 though 30 PAs. He had 34 home runs at Memphis; the bat is not a mystery.
Quinn Mathews (AAA, LHP, Rank: 10) · was recalled on August 17 as an extra man for the double-header. He started and threw 4 innings, striking out 7 and walking 3. He yielded 2 hits and a run. He was optioned back to Memphis on August 18. He owns a 3.27 ERA across 99 innings and 21 starts at Triple-A this season, with 120 strikeouts and 61 walks.
Trevor Condon (A, OF, Rank: 5) · received his first promotion to full-season ball on August 18, moving from the FCL to Palm Beach. He is hitting .444/.444/.556 through 9 plate appearances in A ball, a small but encouraging debut at a new level for one of the system's better-regarded outfield prospects.
Yairo Padilla (A+, SS, Rank: 17) · jumped from Palm Beach to Peoria on August 18. He slashed .281/.354/.474 with 3 home runs and 10 steals across 128 plate appearances at A ball before the bump. The early A+ sample of 8 plate appearances is too thin to read into, but the promotion itself reflects organizational confidence in a switch-hitting shortstop who has drawn walks at a strong clip all season.
Ixan Henderson (AAA, LHP, Rank: 26) · was placed on the 60-day injured list on August 19. Injury details have not been confirmed. He had made just one appearance at Triple-A this season before the placement, posting 4.1 innings with 4 walks and no strikeouts. Combined with stints at FCL and Palm Beach, the season had been a rough developmental year before the IL news.
