Matz and Lugo have been on the disabled list since the start of the season, Matz with left elbow inflammation and Lugo with right elbow inflammation. Alderson said both will return as starters, almost certainly pushing Robert Gsellman into the bullpen.
Matz and Lugo both pitched well in Minor League starts Sunday, with Matz especially good over five perfect innings for Triple-A Las Vegas. But in part because Matz only threw 73 pitches Sunday and in part because of a schedule that includes two off-days next week, the Mets decided to have him make another start for Las Vegas this week.
