Scottsdale, Arizona —— After his eighth professional appearance on Monday night, San Francisco Giants left-handed pitching prospect Seth Corry is 0-1 with a 1.88 ERA over those eight games (five starts) for the rookie-level AZL Giants, with 14 strikeouts over 14.1 innings pitched against only five hits, but already 13 walks. I observed the 18-year-old Utah native in his August 7 start at home in Scottsdale Stadium against the AZL White Sox; below is Baseball Census‘ full Seth Corry scouting report, including video.

Seth Corry Scouting Report — Notes
A high school lefty from Utah who has thrown 14.1 professional innings in his career, 18-year-old Seth Corry didn’t have his best day on Monday when I saw him pitch in the Arizona League, struggling with command issues from the start of the game that prevented him from setting up and establishing his above-average curveball. The lefty offers a low-90s fastball with modest arm-side run and some sink when he’s on, but on Monday night Corry was off in release point consistency and left his fastball high and arm-side far too often, failing to work ahead consistently. It’s obvious he’s deceptive as he is effectively wild, though, and his fastball can miss bats with sneaky velocity and good late movement when it’s down in the zone. That just didn’t happen enough last night.
His changeup is interesting, and I think it could become significantly better than average down the road. Because the San Francisco Giants lefty failed to spot his fastball last night, he opted to use his changeup more than his curve, and at times the change showed very good tumble with deception thanks to consistent arm speed. It’ll take some time for him to really establish it in the zone with consistent depth, but he has good feel for it already and that’s a very good sign, especially for a pitcher from a cold-weather high school who played two sports in his prep days, limiting his time on a mound to build changeup feel. It’s a shame to have seen him on such an off night, though; Seth Corry has life on all of his stuff, and it’d have been fun to see just how good his curveball is in game action.
No player is defined by their best or worst games, and that ought to be the takeaway with Seth Corry after Monday. It was definitely the worst game of his professional career — a career that’s spanned all of eight games. It happens. Adjustments will come and he’s liable to find his release point again by his next start. (In his most recent start before Monday, on August 2, Corry twirled four scoreless innings with no hits, no walks, and four strikeouts.) There is one thing I really, really liked about Seth Corry last night though: as he started to struggle and lost control of his fastball, he slowed the game down and became deliberate on the mound. Most young pitchers have a tendency to stress out and speed up when facing adversity, trying to do too much and pressing too hard to change their luck. Corry opted to become more deliberate during his struggles: he took a breath, took a pause, and slowed the game down with the hopes of figuring out his release point and command issues. It didn’t happen, of course, but his pacing adjustments are a serious sign of maturity, and that alone makes me interested in seeing Seth Corry develop both in the short term (hopefully I’ll see him pitch again in the AZL later this week) and in the long run with the San Francisco Giants over the next several years.
