SF Giants Prospects Weekly Rundown: Double-A

Notable Performers

Michael Plassmeyer: 1 G, 1 GS, 0.2 IP, 6 H, 4 R (4 ER), 1 BB, 2 K, 54.00 ERA
Matt Frisbee: 1 G, 1 GS, 5 IP, 5 H, 3 R (3 ER), 1 HBP, 1 BB, 3 K, 5.40 ERA
Luis Amaya: 2 G, 4 IP, 3 H, 1 R (1 ER), 0 BB, 5 K, 2.25 ERA
Joey Marciano: 2 G, 3 IP, 1 H, 0 R, 0 BB, 1 K, 0.00 ERA

With Sean Hjelle promoted to Richmond and Caleb Kilian traded to the Cubs, there is a big void that exists at the top of the rotation for the Flying Squirrels that coaches hope Michael Plassmeyer can fill up. In his last three starts, however, Plassmeyer has been rocked for an 8.31 ERA in 13 innings of work. He struck out 18 hitters and only walked four but the big issue is the loud contact that he gave up with 21 hits and five home runs within the stretch. The left-hander now has a 4.73 ERA but is vastly split in his home-road splits with a 6.00 ERA on the road but a 2.06 ERA at home.

The Giants are also hopeful that returnee Matt Frisbee could fill up the void. His three starts since coming back are not particularly positive, however, with a 4.96 ERA. There is nothing particularly problematic with Frisbee’s peripherals as he is still throwing strikes at an above-average rate at 67%. The problem is the vast increase in terms of the loud contact that he gave up, particularly home runs.

A couple of left-handers were effective this week. Both Luis Amaya and Joey Marciano were lights out this week after struggling a bit the previous week. Amaya is on a roll in his last six outings with a 2.31 ERA in 11.2 innings pitched with a 16:3 strikeout to walk ratio. Marciano, on the other hand, has slightly fallen off the rails after a superb start to his 2021 season with a 4.91 ERA in his last 21 appearances and was a heavy victim of the BABIP gods with a .348 rate. Both Amaya and Marciano could see time in Sacramento next season.
