Giants recall right-hander for MLB debut

The Giants announced that right-hander Sean Hjelle has been optioned to Triple-A Sacramento, with fellow righty Carson Seymour recalled as the corresponding move. Seymour was already on the 40-man roster but will be making his major league debut as soon as he gets into a game.

Seymour, 26, was a sixth-round pick of the Mets in 2021. He went to the Giants as part of the 2022 deadline deal which sent Darin Ruf to the Mets and J.D. Davis to the Giants. He has continued climbing the minor league ladder with solid results.

The righty spent 2023 at the Double-A level, primarily as a starter. He logged 112 2/3 innings over 23 starts and five relief appearances, allowing 3.99 earned runs per nine. He struck out 24.5% of batters faced, gave out walks at a 9.2% clip and got grounders on 49.5% of balls in play. He moved up to Triple-A last year with those numbers holding fairly steady. He logged 134 1/3 innings with a 22.1% strikeout rate, 10.1% walk rate and 53.5% ground ball rate.

In November of last year, the Giants added Seymour to their 40-man roster, not wanting him to get plucked away in the Rule 5 draft. He has largely continued to produce in the same manner as previous years. He has thrown 74 innings over 15 starts so far this year with a 3.89 ERA, 25.6% strikeout rate, 11.4% walk rate and 53.6% ground ball rate.

Baseball America currently lists Seymour as the #18 prospect in the Giants’ system, noting that his two-seamer is good at getting grounders while his slider is his best swing-and-miss pitch. BA has some concern about his inconsistent changeup, which leads them to think he may end up as a middle reliever. FanGraphs is a bit more bullish, having given him the #6 spot in the system coming into the year, believing his sinker is an effective enough weapon against lefties to soften platoon concerns, thus giving him a bit more chance to stick as a starter.

For now, Seymour is likely coming up to give the Giants a fresh bullpen arm. They are three games into a stretch of playing 16 in a row. Hjelle pitched in each of the first three contests and may not have been available for the next few days. Seymour will get his roster spot, putting him in position to face major league hitters for the first time.
