Matz (lat) was placed on the 15-day DL on Friday, retroactive to July 6. The Mets held a press conference Friday, during which Matz said that he believes his injury is "just a minor thing." However, the official diagnosis is a partially torn left lat muscle, and the team is reportedly looking at three weeks as an absolute best-case scenario for his return. Matz was treated with a platelet-rich plasma injection after the tear was discovered.
