Make sure to revisit our weekly SF Giants prospect rundowns to keep up with each of the organization’s minor-league affiliates. If you do not feel well acclimated to the prospects throughout the farm system, you might want to revisit our prospect week articles that detailed the system from the top prospects to lower-level fringes. If you’re just interested in the biggest names, then the preseason SF Giants top 31 prospects list is the one-stop-shop for you.

Because of the midseason MVPs post last week, this week’s weekly rundown will cover the past two weeks of action.

SF Giants Prospects Weekly Rundown: Triple-A

Notable Performers

Norwith Gudino: 2 G, 1 W, 4 H, 2 R (1 ER), 2 BB, 9 K, 1.50 ERA
Kervin Castro: 3 G, 2 W, 7.2 IP, 7 H, 4 R (4 ER), 2 BB, 14 K, 4.70 ERA
Matt Frisbee: 2 G, 2 GS, 10.2 IP, 17 H, 7 R (7 ER), 4 BB, 15 K, 5.91 ERA

One of the breakout relievers in the system is Norwith Gudino. The 25-year old was a starter prior to this season but with middling results. When the Giants converted him to a full-time bullpen arm, Gudino started to shine. His numbers in Richmond were very impressive, with a 1.44 ERA and 39 strikeouts to just 10 walks in 25 innings of work. What’s more amazing is that he has a 42.6% whiff rate. His whiff rate in Sacramento is only at 28.2% across three outings and he had a rough debut, but he’s righted the ship with a 31.4% whiff rate in his two outings in the past two weeks. He generates a very high amount of whiffs due to his plus fastball that sits in the 94-97 MPH range, hard slider, and a nasty splitter.

Kervin Castro‘s scoreless inning streak ended at 14.2 innings pitched and has hit a bit of a hiccup, but pitched his best outing this season in his latest appearance, pitching three spotless innings of work with six strikeouts. He induced 10 whiffs on his latest outing and his curveball was spot on. Castro is could potentially be a part of some package deals as the trade deadline comes closer, but he could be a primary option to pitch in the Giants bullpen this season.

Matt Frisbee has been a big victim of the long ball since getting promoted to Sacramento as the right-hander already allowed 15 big flies in just 44 innings of work after giving up three more big flies over the past two weeks. He has the swing and miss stuff rolling recently, with a 31.3% whiff rate in his last three starts. Frisbee now has 38 strikeouts in Triple-A.
