NEW YORK (CBSNewYork) — You can’t stop Matt Harvey. You can only hope to contain him.

And so far, the New York Mets have had a hard time reining in the ultra-competitive pitcher.

Mets manager Terry Collins said that he wants to see Harvey ease up in his rehab from Tommy John surgery. Not throwing so hard would be a start. He and pitching coach Dan Warthen planned to speak with the 25-year-old about slowing things down on Wednesday, but Harvey was on the phone with a New York radio station instead.

“To be honest, one of the reasons why we have tried to back Matt off is because how he is mentally,” Collins said. “This guy is a bulldog. There is no such thing as low speed, low gear. He’s all-out forward.”

Collins appeared frustrated with Harvey’s latest throwing session on in Port St. Lucie.

“The phone call was made (Tuesday), where (Harvey said), ‘Look, I have to back this down a little bit.’ And yet today he went out and threw a 27-pitch bullpen,” Collins said. “I’m going to put my head through the wall.”

Mets general manager Sandy Alderson, concerned after Jeremy Hefner’s return from Tommy John surgery hit a major setback, said this week that Harvey might have to reassess his timetable, adding the pitcher might not pitch in any games until spring training.

Meanwhile, Harvey has made it clear — repeatedly — that he’d prefer to return before the end of the season.

“I threw a bullpen today and I didn’t miss a spot,” Harvey said during the radio interview Wednesday. “I felt like I was easily throwing into the low- to mid-90s, with pretty much no effort.”

“I know there’s a process,” he added, “but as a competitor I want to get out there as soon as possible.”
