SF Giants Prospects Weekly Rundown: Triple-A
Kervin Castro: 2 G, 2 W, 4 IP, 1 H, 0 R, 0 BB, 3 K, 0.00 ERA
Matt Frisbee: 1 G, 1 GS, 5 IP, 3 H, 2 R (2 ER), 1 BB, 1 K, 3.60 ERA
Sam Selman: 2 G, 0 H, 0 R, 2 BB, 4 K, 0.00 ERA
Kervin Castro is on a roll. After a rough May where the right-hander had more walks than innings pitched and an ERA of 6.00, he’s surrendered just two earned runs ever since and has thrown seven straight scoreless outings with a nine-to-two strikeout to walk ratio and has thrown 64% of his pitches for strikes. The 22-year old has separated himself from the duo of Gregory Santos and Camilo Doval, and has a big chance to pitch in the bigs at some point in the season.
After four excruciating starts, Matt Frisbee finally had a strong outing as a River Cat with five innings of two-run ball. He was efficient with only 66 pitches thrown and was helped by the BABIP gods this time. He only had one strikeout, the third time in five starts that he’s exactly had one K. I did not see any drastic difference in the way that he pitched in terms of approach, he was just more effective. His BABIP in AAA lowered from .352 to .310 after this start, an indication that there could be better days ahead. Still, he’ll need to find some punchouts soon.
Even though he’s already well-known to the Giants fanbase, Sam Selman still has prospect eligibility in some rankings. He was hitless this week and struck out four across three innings but it was the walks that have hurt him this season with a 17% walk rate, his highest in three years. Selman can still be an effective left-handed option out of the pen. But with the big league club trying to win now and potentially looking externally to help improve the back-end of the bullpen, he could be on the outside looking in.
