Mets designated RHP Walker Lockett for assignment.
The Mets needed to clear a spot on the roster for David Peterson’s return from the injured list, and Lockett was the odd-man out. It’s a really tough break for the right-hander, who picked up his first victory of the season on Friday -- working a pair of shutout innings with three strikeouts in relief of Michael Wacha in the first game of their doubleheader against the Yankees. He owns a 5.63 ERA and 1.50 WHIP on the season. Given how many teams are starved for pitching depth, he may attract interest on waivers.
