The Mets have reinstated first baseman Pete Alonso, outfielder Kevin Pillar and reliever Seth Lugo from the injured list, Tim Healey of Newsday was among those to report. In other moves, the Mets designated outfielder Cameron Maybin and right-hander Sam McWilliams for assignment; selected outfielder Mason Williams; and optioned outfielder Khalil Lee, catcher Patrick Mazeika and reliever Sean Reid-Foley.

The returns of Alonso, Pillar and Lugo (all previously reported) will add some reinforcements to a New York team that has been ravaged by injuries this year. Despite their health issues, though, the Mets have started a solid 25-20 en route to a 3 1/2-game lead in the National League East.

Thanks in part to their injuries, the Mets acquired Maybin from the Cubs on May 18. The Mets bought extremely low on Maybin, whom they picked up for a dollar, but they got little bang for their buck. The 34-year-old totaled 33 plate appearances, collected one hit (a single) and struck out 12 times before they designated him.

McWilliams, meanwhile, signed a major league contract with the Mets last offseason despite having never pitched in the bigs. He also hasn’t reached the majors this season, instead throwing 8 1/3 innings of 10-earned run ball at the Triple-A level. The 25-year-old owns an ugly 8.60 ERA with 53 strikeouts against 25 walks in 52 1/3 Triple-A frames.
