​Not much went right for the Mets on Sunday.Off the field they continued what’s shaping up to be a massive trade deadline sell-off, shipping Freddy Peralta out to the Tampa Bay Rays in a deal for three prospects.On the field their offensive struggles continued, as they went a combined 0-for-12 with runners in scoring position and left a total of 10 men on-base, suffering their 11th shutout loss to the season.One of the lone positives, though, was the performance from Robert Stock.The 36-year-old right-hander was spectacular making his first MLB start since 2021, mowing down the Marlins lineup across a career-high five innings of work.“Really impressive, his stuff is good,” interim manager Andy Green said.Stock retired the first six batters he faced before running into some trouble following two singles in the third, but he was able to set down Kyle Stowers on strikes to strand the pair.The righty followed that with a perfect fourth, but the Marlins were able to finally break the scoreless tie in the fifth, as young catcher Joe Mack smacked a solo homer to right.Stock retired the next two to end his strong big-league return with just the one run allowed on three hits while striking out four over five terrific frames.“It felt great,” he said. “Thinking about where I was a couple of months ago where I couldn’t even put my arm over my head to pitching today in Citi Field, it was as much of a dream come true as could be.”Stock, a career journeyman, spent the past four months progressing his way back in the minor league after being diagnosed with thoracic outlet syndrome in March.He impressed in his eight rehab appearances down there and was able to  carry that success over into his MLB return, putting him in the mix for a rotation spot with the selling Mets down the stretch.“He should take a lot of pride in the way he threw the baseball today,” Green said. “He earned the right to be in the conversation at this point in time, and we’ll definitely have that conversation.”
