Bob Seymour

The Rays announced that first baseman Bob Seymour has been released to pursue an opportunity in Asia. No details were provided about which team or country he is heading to. He was already off the 40-man roster, as he was designated for assignment last week.

Seymour, 27, has spent his entire professional career with the Rays thus far. A 13th-round pick from the 2021 draft, he crushed homers throughout his minor league career but also struck out quite a bit. In 2024, he launched 28 long balls in 123 games, split between Double-A and Triple-A. He slashed .281/.351/.523 for a 139 wRC+ but was also punched out in 30.6% of his plate appearances. In 2025, he hit 30 homers in just 105 Triple-A games. He had a .263/.327/.553 line and 122 wRC+ while striking out at a 25.7% pace.

He got called up in mid-August and spent about the final six weeks of the season in the big leagues. He stepped to the plate 83 times but struck out in 32 of those, a 38.6% pace, leading to a rough .205/.253/.282 line.

Despite the obvious power, Seymour has never really ranked as a notable prospect. He only plays first base and doesn’t have wheels, which means he has to hit to provide value. Given how often he strikes out, it was going to be hard for him to be a viable big league bat.

He still has a full slate of options. Even if he were claimed off waivers after being designated for assignment this week, he was likely destined for another year of riding the bus in Triple-A. Instead, he’ll head overseas somewhere, presumably for a bigger paycheck and a better opportunity. If he finds success wherever he is going, perhaps he will return to North America someday.

The Rays are planning to call up first base prospect Bob Seymour from Triple-A Durham prior to Friday’s game, according to Marc Topkin of the Tampa Bay Times.  Since Seymour isn’t on the 40-man roster, Tampa Bay will have to make at least one corresponding move to create space on both the 40-man and 26-man rosters.

The 26-year-old Seymour will be making his MLB debut whenever he appears in his first game.  A 13th-round pick for the Rays in the 2021 draft, Seymour has been productive at every level of the minor league ladder, including big numbers in Durham in each of the last two seasons.  Seymour has hit .263/.327/.553 with 30 home runs over 443 PA at Triple-A this year, and his 30 homers lead the International League.  Just this past Tuesday, Seymour highlighted his huge year with a three-homer game against Triple-A Nashville.

As evidenced by his 89 homers over 1736 career PA (and 410 games) in the minor leagues, there’s a lot of pop in Seymour’s bat.  There was also a lot of swing-and-miss, though Seymour has significantly reduced his strikeout rate from 34.9% in 2024 (in 218 PA with Durham) to 25.7% over his 443 PA this season.  He also enjoyed some inflated BABIPs in past seasons, yet a more neutral .292 BABIP in 2025 indicates that the first baseman isn’t just relying on a lot of good fortune.

Despite all this power, neither MLB.com or Baseball America list Seymour among the top 30 prospects in Tampa’s farm system.  It seems as though Seymour is viewed in limited terms as a first base-only player who has only big power and hard-contact skills as calling cards, yet evaluators may doubt that those abilities can translate into production against Major League pitching.

Still, it’s hard to argue that Seymour’s big 2025 campaign hasn’t earned him at least a look in the Show.  Seymour is a left-handed hitter who could replace Jonathan Aranda in the lineup to some extent, playing mostly as a designated hitter since Yandy Diaz is locked in at first base.  Aranda is one of five Rays position players on the injured list, so with Tampa Bay a little thin on the bench, there are worse ideas than calling up a 30-homer slugger.
