The Red Sox announced that outfielder/designated hitter Masataka Yoshida has been reinstated from the injured list, with first baseman Garrett Cooper designated for assignment in a corresponding move. Chris Cotillo of MassLive was among those to relay the moves on X.

The Sox have been scrambling to fill their first base and designated hitter mix since late April, as both Yoshida and Triston Casas landed on the injured list around the same time. They acquired Cooper from the Cubs in a cash deal and also signed Dominic Smith.

Neither Smith nor Cooper have played especially well, but Cooper’s results were far worse. Smith has two home runs and has drawn a walk in 11.7% of his plate appearances, leading to a .221/.325/.327 batting line and 88 wRC+.

Cooper, meanwhile, was hitting .270/.341/.432 for the Cubs before the deal but produced a bleak line of .171/.227/.229 since coming to Boston. Now that Yoshida is back, Smith gets to stay while Cooper has understandably been nudged off the roster by that poor performance.

The Sox will now have a week to trade Cooper or pass him through waivers. Given his poor results, the interest is likely to be tepid. He’s played a bit of corner outfield but is primarily a first baseman, where the offensive expectations are generally higher than up-the-middle spots.

Cooper at least has some decent results in his past that could help him generate interest. He hit .274/.350/.444 for the Marlins over the 2019 to 2022 seasons, with that performance translating to a 117 wRC+. Staying in the lineup was an issue, as various injuries limited him to 331 games over that span of three full seasons and the shortened 2020 campaign.

He then slumped a bit in 2023, despite a career high 17 home runs, as he struck out in 28.9% of his plate appearances and slashed .251/.304/.419 for a 96 wRC+. He had to settle for a minor league deal with the Cubs and got onto their major league roster. As mentioned, he performed pretty well, but in a small sample of 12 games. Though his decent batting line with the Cubs was buoyed by a .391 batting average on balls in play and also masked a 31.7% strikeout rate. The Cubs decided to move on in a move that was somewhat surprising at the time but seems wise in retrospect, given how far Cooper’s results have fallen in the interim.
