ST. PETERSBURG, Fla. - Terry Collins used his day off Thursday to visit the Mets' minor-league complex in Port St. Lucie. While there, he got a look at the progress of Long Island lefty Steven Matz, who is recovering from a partially torn muscle in his left side.

"Matz was great, too," Collins said after answering a question about David Wright's rehab. "He'll be on a mound next week. Watched him long toss. It was impressive."

Matz has been out since July 6 after bursting on the scene with a pair of winning starts. Collins said Matz was throwing "free and easy" and could be a factor for the Mets in September. "He's a ways away yet," Collins said. "His arm's coming back."

As for Wright and his troublesome back, Collins said there was no update. Wright is going through a five-day intensive workout program that the team hopes will allow him to start playing rehab games on Monday.

"No news is good news," Collins said. "I watched him [Thursday]. Another good day for him. Took a good batting practice. I think [Saturday] is his last day and he's going to have Sunday off and get in a game on Monday . . . Right now, we're hoping that Monday he gets in a game."

Regarding Rafael Montero (shoulder), whom Collins saw throw two innings in a Gulf Coast League game, the manager said: "He's not ready yet."
