Collins said he's "not sure it's fair" to ask Matz to warm up in a hurry as a reliever. "You're talking about a guy with injury issues," Collins said.
Matz will make another minor-league rehab start Monday, when he's expected to throw around 80 pitches, according to B-Mets reporter Lynn Worthy (Aug. 27, 5:10 pm).
Matz allowed one hit over six shutout innings during a rehab start for Double-A Binghamton on Wednesday night, striking out six with no walks in threw 56 pitches (41 strikes) while the last 16 batters he faced. He was making his third rehab start and was on a 60-pitch limit.
Matz, 24, was 2-0 with a 1.32 ERA in two big-league starts before going on the disabled list in early July due to a partial lat tear.
