SF Giants Prospects Weekly Rundown: Double-A

Notable Performers

Caleb Kilian: 1 G, 1 GS, 1 W, 1 CG, 1 SHO, 7 IP, 3 H, 0 R, 1 BB, 4 K, 0.00 ERA
Sean Hjelle: 2 G, 2 GS, 8.1 IP, 5 H, 3 R (1 ER), 2 BB, 9 K, 1.08 ERA
Mac Marshall: 1 G, 2 IP, 2 H, 0 R, 1 BB, 3 K, 0.00 ERA

Is it fair to say that Caleb Kilian is really good? He pitched his first completegame shutout of his professional career (albeit in a doubleheader) and he’s brought his ERA even lower to 2.09. If you want to nitpick on any negative is that he ended his four-game streak of inducing double-digit whiffs with just eight in seven innings of work. Still, he’s certainly playing like a top 10 prospect right now.

After missing a bit of time due to injury, Sean Hjelle‘s back on the bump for the Flying Squirrels this week and has continued to pitch well this season with an ERA of 3.00. He’s showing that he’s losing his effectiveness when pitching the second time through a batting order. A future move to the pen is more than likely to become an effective big leaguer where he can sit in the mid-90s and become a potential late-inning option for the big league club. Then again, he can hit too.

Mac Marshall has had a rough 2021 to say the least. The 25-year old has battled injuries throughout his minor league career and this year is no different as he missed a month of action due to injury. In his return this week, he pitched two scoreless innings where 24 of his 35 pitches were strikes. The left-hander has shown his grit and work ethic to continue to achieve his big league dreams and he has the stuff to do so (low to mid-90s fastball and a 55-grade curveball).
