SF Giants Prospects Weekly Rundown: Triple-A
Kervin Castro: 1 G, 2 IP, 1 H, 0 R, 1 BB, 3 K, 0.00 ERA
Camilo Doval: 2 G, 1.1 IP, 2 H, 0 R, 0 BB, 3 K, 0.00 ERA
Sean Hjelle: 1 G, 1 GS, 5 IP, 10 H, 5 R (5 ER), 3 BB, 2 K, 9.00 ERA
What a roll Kervin Castro is on this season for the River Cats. The 22-year old is pitching to the tune of 1.20 ERA in his last eight appearances with a 20 to 5 strikeout to walk ratio in 15 innings of work. There seems to be a pattern of work for Castro all season as he is pitching every fourth or fifth day and has pitched at least two innings of work in 10 of his last 13 appearances with a 2.08 ERA and has only allowed a .191 opponent’s batting average. While he is pitching very well, the next thing for Castro is pitching effectively with fewer days of rest.
After struggling for most of this season, Camilo Doval has found his groove this August with seven scoreless outings in both Sacramento and San Francisco. He has not allowed a walk in his last six outings and has a nice 69% strike rate over that stretch with 11 strikeouts in 6.1 innings of work. Hopefully, this is the start of things trending in the right direction for Doval.
Sean Hjelle‘s start to his Sacramento career has been rough. The 2018 second-rounder has a 6.23 ERA in his three starts for the River Cats with almost twice as many walks as strikeouts (9 walks vs. 5 strikeouts) in 17.1 innings. Upon watching his starts, Hjelle has a little problem throwing over the strike zone but is failing at executing his pitches and his stuff is getting timed by minor league veterans quickly. He’s nibbling instead of attacking hitters even though his mid-90s fastball velocity should be enough to get outs.
