Mets Designate Connor Grey For Assignment

The Mets have designated righty Connor Grey for assignment, per a team announcement. His spot on the roster will go to journeyman infielder Deven Marrero, whose previously reported selection from Triple-A has now been made official. New York also recalled right-hander Adonis Medina as the second of their two September call-ups.

Grey, 28, hasn’t pitched in the Majors to this point in his career but was added to the Mets’ 40-man roster last month amid a series of roster moves to get some fresh arms in the ’pen. Grey has made 21 starts and a relief appearance in Triple-A Syracuse but struggled to a 5.52 ERA with lackluster strikeout and walk ratios (17.9% and 9.5%, respectively).

Originally a 20th-round pick by the D-backs in 2016, Grey posted solid numbers up through the Double-A level but has yielded an ERA north of 6.00 in parts of three Triple-A seasons. He’ll be placed on outright waivers or released within the week.

Medina, 25, will give the Mets an extra arm in the bullpen. The former Phillies top prospect has appeared in 13 games with the Mets this season and tallied 23 1/3 innings while pitching to a 4.63 ERA. He’s logged a below-average 16.5% strikeout rate but also walked only 4.9% of his opponents in that small sample. Medina has a 3.71 ERA in 26 1/3 innings with Syracuse, though he’s walked a much more problematic 12.1% of his opponents there.
