Carson Seymour

Organization Prospect Rankings

• 
  Ranked San Francisco Giants #21 prospect in 2024
  BA Grade: 40/High
  
  Track Record: Seymour was originally selected by the Mets in the sixth round of the 2021 draft. He was traded in 2022 with lefty Nick Zwack as part of a four-player package that brought outfielder Darin Ruf to the Mets. Seymour split his 2022 season between the Class A levels, then spent all of 2023 at Double-A Richmond. His 114 strikeouts were the third-most in the system.
  
  Scouting Report: Early in the year, Seymour made too many mistakes in the middle of the plate. To correct the issue, he and the Giants worked on refining the way he mixed his four- and two-seam fastballs, which each sit around 94 mph and have peaked at 97. As a result, scouts say, Seymour’s slider became more effective. The pitch is thrown between 88-92 mph and shows tight gyro shape with short, sharp break. He threw a curveball during the season but now exclusively uses the slider. Seymour’s changeup is a clear fourth pitch in his mix and was thrown just 2% of the time in 2023. It’s a well below-average offering that will need to take serious steps forward if Seymour is to remain a rotation option. He works from the stretch only and has a short arm action in the back.
  
  The Future: Seymour will move to Triple-A in 2023, where he will be tested by the confines of the automatic ball-strike system. He looks like a reliever who leans heavily on his fastball-slider combination.

• 
  Ranked San Francisco Giants #12 prospect in 2023
  BA Grade/Risk: 50/High
  
  Track Record: Seymour began his college career at Dartmouth and transferred to Kansas State, which forced him to sit out the 2019 season. The redshirt year plus the lost pandemic season added up to a severely stunted college career, which ended with just 84.2 innings in three seasons. The Mets drafted Seymour in the sixth round in 2021 and traded him to the Giants a year later as part of the four-player package that sent Darin Ruf to New York.
  
  Scouting Report: Seymour is a big, 6-foot-6 righthander with twitchy athleticism and the potential for a four-pitch mix. He gets a great deal of his outs with his high-octane fastball and a short, sharp, cutter-slider hybrid. His fastball sits in the mid 90s and peaks at 97 while his slider hovers in the upper 80s and scrapes 91. His fastball is not especially effective at getting whiffs or chases, but his slider is an above-average swing-and-miss pitch. Seymour also has a true downer curveball in the low 80s that gives him an excellent weapon against lefthanded hitters. He has a seldom-used changeup, but the Giants have considered switching it to a split-fingered fastball that better fits his massive hands. Seymour has some reliever risk because of a long arm action and below-average command, but he limits his walks and season and throws strikes at a solid clip.
  
  The Future: Seymour will get his first upper-level test in 2023 at Double-A Richmond. If he can improve his command, he could be a No. 4 starter.

Draft Prospects

• Ranked #292 prospect in 2021 draft
  The 6-foot-6, 260-pound righty has impressive stuff, but hasn’t spent a lot of time on the mound in his collegiate career between stops at Dartmouth, the Cape Cod League, the Northwoods League and Kansas State. Seymour has a fastball that has been up to 99 mph, he’s flashed a plus slider at 90, and he has a good changeup but he hasn’t often been able to get to his secondaries. The fastball has generic life and doesn’t play to the velocity and he doesn’t have a ton of control so he’s always behind in counts without an opportunity to spin his breaking ball or use his changeup. Some believe he might be better off throwing sinkers rather than his four-seamer, but he’s a big guy with good stuff who should get a chance. There are questions about his ability to start but there aren’t many pitchers who throw as hard with the slider he has. Seymour is inexperienced and hasn’t had success getting outs, but the stuff is worth a look.
• Ranked #160 prospect in 2020 draft
  If the season had played out through June, it’s possible Seymour would have pitched his way into the second round or even higher—or he could have pitched his way out of serious draft consideration. There aren’t many starting pitchers in the draft that can sit in the mid-90s and touch 97-99 mph, and Seymour’s fastball is lively and gets plenty of swings and misses. Seymour also has a slider and a curveball, with the slider being a true plus swing-and-miss two-plane pitch and the downer high-70s curve also flashing above-average potential. But there is no track record to speak of with Seymour So far, he’s just scratching the surface of what he may become, and there are times the game speeds up on him. He pitched ineffectively and infrequently as a reliever as a freshman at Dartmouth before transferring to Kansas State. After redshirting in 2019, he posted a 5.06 ERA with 15 walks in 26.2 innings in the Cape Cod League last summer. Even this spring, he struggled with consistency, getting knocked out in the fifth inning of games against UT Rio Grande Valley and Texas A&M Corpus Christi. Seymour is a big-bodied pitcher (6-foot-5, 250 pounds) who has gotten into better shape. As a draft-eligible sophomore with first-round potential, Seymour may opt to return to school, but a team willing to take a risk could potentially land a pitcher whose best days are still far ahead of him.

• April, 2022 Scouting Report
  BA Grade: 45/Extreme
  
  Midseason Update: A sixth-round pick last year out of Kansas State, Seymour leans on a power groundball repertoire to get outs. The athletic, 6-foot-6 righty throws hard but doesn&#39t miss as many bats as expected, suggesting a potential future bullpen role. The 23-year-old reached High-A this summer on the strength of a 94 mph sinker, complemented by a mid-90s four-seamer, cutter, curveball and changeup.
