Caleb Kilian pitched his first seven-inning complete game for the Flying Squirrels last week, but his strikeout rate has plummeted since he got promoted to Double-A. After looking at his game logs, his whiff rate in Double-A went down drastically when compared to his High-A numbers. This sudden drop in strikeouts could be the combination of the much-improved competition and the lack of impact secondaries that I noted in my previous prospect rundown. He’s still getting the job done nonetheless, but it’s definitely something to note moving forward.

Sean Hjelle‘s having a strong 2021 season for the Flying Squirrels. He’s pitched at least five innings in his last four starts, and he’s had terrific strikeout and walk rates even though he’s allowing almost a hit an inning. He’s lowered his arm slot this season and based on the eye test, it helped him create a better tunnel with his curveball compared to previous years. Stamina’s still an issue for Hjelle but it looks like he is a lock to pitch five strong innings in a big-league rotation.

Gerson Garabito turned in a strong start last week and his performance this season earned him a Triple-A call-up. The 25-year old minor league free agent signee’s numbers for Richmond are not exceptional but he’s pitched better than what the traditional numbers tell but mixing and spotting his pitches well.

Moving to the bullpen, the trio of Jose MarteNorwith Gudino, and Joey Marciano have been dominant for the Richmond pitching staff. Outside of a four-run stinker against the Altoona Curve more than a week ago, Marte has been lights out with two hits, two walks, no runs allowed, and 12 strikeouts in 5.2 innings pitched. With his triple-digit heat and wipeout slider, he’s poised for a potential big league call-up later this season.

Gudino has continued to be a rock-solid back-end piece in the Richmond bullpen, as he is sporting a 1.47 ERA this season. He generates plenty of whiffs with his stuff but he is more control over command. On the left side, Marciano continued to be dominant, using his mid-90s fastball and curveball combination to baffle hitters to the tune of 0.60 ERA this season. Both could potentially get called up to Triple-A at the mid-season mark.
