Mets Activate Michael Conforto, Select Corey Oswalt

The Mets announced a series of roster moves before this evening’s game against the Braves. As expected, outfielder Michael Conforto has been activated from the injured list. He is in tonight’s lineup, hitting third while playing right field. Right-handers Tylor Megill (previously reported) and Corey Oswalt have been officially selected to the roster. (Andy Martino of SNY reported that Oswalt would be promoted before the official announcement).

Righties Yennsy Díaz and Sean Reid-Foley were optioned to Triple-A Syracuse, while catcher Tomás Nido has been placed on the 10-day injured list, retroactive to June 22, due to a right wrist contusion. To clear 40-man roster space for Megill and Oswalt, pitchers Joey Lucchesi and Robert Gsellman were transferred from the 10-day to the 60-day injured list.

Conforto has been out since May 17 with a hamstring strain. He’ll return to the lineup for the first time in more than a month, looking to improve upon his early-season output. Conforto, who hit .261/.365/.478 between 2018-20, started this season a bit slowly by his standards. Across 135 plate appearances, the left-handed hitter managed a .230/.356/.336 line that’s been only slightly better than league average, a drop-off from his high-end production in prior years. The next few months will be pivotal for Conforto, who is scheduled to reach free agency at the end of the season.

Oswalt becomes the latest addition to a pitching staff that has been hit hard by injuries. The 27-year-old appeared for the Mets in each season from 2018-20, working to a composite 6.19 ERA/4.83 SIERA across 84 1/3 innings. He served as something of a flexible swing option, starting 13 of his 23 MLB appearances.

New York passed Oswalt through outright waivers in February, and he’s spent the 2021 season with Syracuse. He’s made six appearances, none of which has eclipsed 3 1/3 innings, working mostly as a multi-inning reliever. Given that he hasn’t really been stretched out this year, Oswalt seems more likely to serve as long relief depth than as a true starter, although it’s possible he could work as an opener or tandem starter of some sort. Megill, on the other hand, has worked as a more traditional starter in the minors and is ticketed to start tonight’s game against Atlanta.

Gsellman went on the IL with a lat strain earlier this week, and he never seemed especially likely to return anytime soon. General manager Zack Scott told reporters (including Tim Britton of the Athletic) that Gsellman won’t even begin a throwing program for at least six weeks. That likely ruled him out until late August at the earliest, so there’s little reason for the Mets not to transfer the righty to the 60-day IL with the need for 40-man roster space. Lucchesi, meanwhile, will undergo Tommy John surgery tomorrow and miss the rest of the year (and most or all of 2022).

Nido has tallied 91 plate appearances this season, hitting at a passable .238/.297/.393 clip. A recent MRI on his injured wrist didn’t reveal any structural damage, manager Luis Rojas told reporters (including Anthony DiComo of MLB.com) this afternoon. Nevertheless, it seems he’ll need a few days to recuperate. Patrick Mazeika is on hand to back up starter James McCann in the interim.
