J.D. Martinez, who signed a one-year deal to be the Mets’ designated hitter just a week before Opening Day, is dealing with lower back tightness and received an injection for it today. For now, he’ll miss three-to-five days.
The Mets had already said that Martinez was dealing with general soreness and would need a couple of days off to start this week, but this update isn’t ideal. The Mets’ lineup has generally been struggling, though both the lineup and current regular designated hitter DJ Stewart had a big night last night in an 8-7 win over the Braves.
