Cardinal Chronicle Pitcher of the Day: Blake Aita Gives Peoria Exactly What It Needed
The Peoria Chiefs needed one more strong start to finish off a dominant week, and Blake Aita delivered it.
Aita, a 22-year-old right-hander in the St. Louis Cardinals organization, is the Cardinal Chronicle Pitcher of the Day after turning in six scoreless innings in Peoria’s 3-1 win over Beloit, a victory that completed a six-game sweep for the Chiefs.
The line was clean and efficient: 6 IP, 4 H, 0 R, 1 BB, 4 K.
That is exactly what a starting pitcher is supposed to do. Take the ball. Control the game. Avoid the crooked inning. Hand the bullpen a lead with room to breathe. Aita did all of that Sunday, and he did it in the kind of outing that matters for a developing arm trying to establish himself in a new organization.
Aita is not one of the loudest names in the Cardinals’ system, but he is an intriguing arm. Listed at 6-foot-4 and 215 pounds, the right-hander has the frame teams look for in a starter and the strike-throwing foundation that gives him a real chance to keep climbing. He is currently pitching for High-A Peoria, where starts like Sunday’s can begin to change how a pitcher is viewed.
Before joining the Cardinals, Aita built his foundation at Kennesaw State University, where he earned All-Atlantic Sun First Team honors as a sophomore starter in 2024. The Boston Red Sox selected him in the sixth round of the 2024 MLB Draft, 177th overall, and signed him for $300,000.
His professional debut in 2025 was an eye-opener. Pitching for Low-A Salem, Aita opened his minor league career with five no-hit innings in his first professional game. He later earned a promotion to High-A Greenville and finished the season with a solid overall body of work: 3.98 ERA, 1.05 WHIP, and 99 strikeouts in 115.1 innings across two levels.
The Cardinals acquired Aita in December 2025 as part of the deal that sent Willson Contreras to Boston. St. Louis also received right-handers Hunter Dobbins and Yhoiker Fajardo in that trade, giving the organization three arms with different developmental paths and different ceilings.
Aita’s profile is built more on pitchability than overpowering hitters. His fastball generally sits in the low 90s and can touch 95 mph, and he pairs it with a breaking ball, cutter, and continued work on additional weapons to handle left-handed hitters. Since entering pro ball, he has focused heavily on improving his feel for spin while developing both a changeup and splitter.
That development piece matters. At High-A, pitchers are not finished products. They are being shaped. The question is not whether Aita looks like a finished major league starter today. The question is whether he has the body, strike-throwing ability, pitch mix, and aptitude to keep moving forward.
Sunday was a good answer.
There was no panic in the outing. He limited traffic, issued just one walk, and kept Beloit off the scoreboard long enough for Peoria’s offense to build a lead and the bullpen to finish the job. It was not flashy for the sake of being flashy. It was professional, efficient, and exactly what the Chiefs needed.
For Peoria, the win capped one of its best weeks of the season. For Aita, it was a strong reminder that he should not be overlooked in a Cardinals system that continues to search for dependable starting pitching depth.
Aita may still be a developmental arm, but Sunday looked like a step forward.
And for one afternoon in Peoria, he was everything a club wants from its starter.
