Matz has 'very positive' throwing session

No timetable for left-hander's return, but Mets expect him back this season

Matz has 'very positive' throwing session

MIAMI -- Mets rookie Steven Matz took his first tangible step toward a return from the disabled list on Monday, playing catch at the team's rehab facility in Port St. Lucie, Fla. Matz had not thrown since landing on the disabled list July 10 with a partial tear of his left lat muscle.

"Very positive," was how manager Terry Collins described the throwing session. "No problems. I saw him the other day and he felt great, couldn't wait to get back out and play catch, which he did today. So that's a good step."

Matz to miss at least 3 weeks

Matz, 24, went 2-0 with a 1.32 ERA over his first two big league starts. But he began feeling lat discomfort after the first of them, and an MRI following the second outing revealed his partial tear. The Mets still have no timetable for Matz's return, but expect him to rejoin their rotation later this season.
