Marlins Acquire Shaun Anderson, Designate Woo-Suk Go

The Marlins on Thursday acquired recently DFA’ed right-hander Shaun Anderson from the Rangers in exchange for cash, reports Craig Mish of SportsGrid (X link)*. In order to open a spot on the 40-man roster, Miami designated right-hander Woo-Suk Go for assignment.

Anderson, 29, appeared in only two games with Texas, logging 3 1/3 innings and yielding a pair of runs on six hits and a walk with three strikeouts. This marks the fifth MLB season in which he’s seen action at the game’s top level. Anderson has previously suited up for the Giants, Twins, Orioles, Padres and Blue Jays — in addition to a prior run in the Rangers’ minor league ranks. He’s pitched 139 big league innings but struggled to a 5.83 earned run average in that time. He’s intrigued several teams over the years thanks in large part to a high-spin slider that has the potential to be a true bat-missing offering, but the rest of his arsenal hasn’t helped him reach passable results.

Anderson split the 2023 season between the Phillies’ Triple-A club and the Korea Baseball Organization’s Kia Tigers, making 14 starts for the latter. During that brief KBO run, he notched a respectable 3.76 ERA with a 19% strikeout rate, 7.7% walk rate and 61.7% ground-ball rate (though ground-ball rates in the KBO always tend to be higher than in MLB, it should be noted). Anderson is in his final minor league option year, so he can be sent back and forth between Miami and Triple-A Jacksonville freely without needing to pass through waivers.

Go, 25, was one of the top relievers in the KBO in recent years and made his way to North American ball via the posting system this winter. The Padres signed him to a two-year, $4.5MM contract but almost immediately cut bait on him, sending him to the Marlins as a financial counterweight in the Luis Arraez trade earlier in the month. He’s pitched well in Triple-A since the trade, logging nine innings with a 3.00 ERA. However, he’s fanned only 8.3% of his opponents against a 5.6% walk rate.

During his outstanding run with the KBO’s LG Twins from 2019-23, Go posted a collective 2.39 ERA with 139 saves, a 30.2% strikeout rate, a 10% walk rate and a ground-ball rate north of 60%. He missed time in 2023 with a lower back injury but still pitched 44 innings of 3.68 ERA ball with a 31.1% strikeout rate, 11.6% walk rate and massive 65.8% grounder rate.

Scouting reports on Go had his fastball topping out at 98 mph in the KBO, but when he reported to spring training reports out of Padres camp suggested he was in the 92-94 mph range, topping out just shy of 95 mph. Though the Friars had envisioned him as a potential entrant into their late-inning mix, the decision to instead option him (to Double-A) and then include him in the Arraez trade suggests they quickly became less enamored of him once he joined the organization. That the Marlins are now jettisoning him from the 40-man roster suggests they’re similarly unenthused about the right-hander’s chances of contributing at the MLB level.

Because of that $4.5MM contract, Go seems like a lock to clear waivers if he makes it there. Miami will have five days to explore trade possibilities before placing him on waivers becomes a necessity. Waivers themselves would then be a 48-hour process. If Go clears, he’d likely accept an outright assignment to Jacksonville, allowing him to continue collecting his salary while endeavoring to pitch his way into the Marlins’ big league bullpen plans.

*MLBTR originally mistakenly indicated the Marlins had formally announced the trade for Anderson and DFA of Go. The team had not done so yet at the time. We regret the error.
