Harvey, a rookie, starts for the Mets on Tuesday and will likely get one other start according to a plan put in place by general manager Sandy Alderson and manager Terry Collins.
The Mets' top Draft choice in 2010, Harvey has thrown 152 1/3 innings this season, including 110 innings at Triple-A Buffalo.
The New York brass, like the management in Washington, is taking a cautious approach to its prized pupil.
"You look at what's best for the player, which is what we will always do," Collins said. "Two more starts, possibly three depending on what he does in the next two starts. If he has a bad night, there might be a third one in there somewhere."
The 23-year-old Harvey is 3-3 with a 2.76 ERA in seven starts. He has allowed two earned runs or fewer in six of those starts.
Harvey has accepted the innings limit, although he says he feels no fatigue. Still, he realizes that he must do what is best for his future. Plus, he has the utmost trust in the New York front office.
"Those aren't my calls, whatever they decide is fine," Harvey said. "I'm going to prepare mentally and physically for the rest of the season. If they ever decide to bring me back, I'd like to be ready for it."
Harvey was a combined 13-5 last season at Class A and Double-A and had a 7-5 mark at Buffalo before being recalled. Collins, among others, is pleasantly surprised by Harvey's performances to date.
"I see much better stuff up here than the reports I got from the Minor Leagues," Collins said. "As he continues to pitch at the Major League level, he's going to get better. He's just driven like that."
Harvey, who went to the University of North Carolina, has struck out 49 batters and walked 17.
"If I can go out and command from the first pitch and keep going after the guy, then I'm doing my job," Harvey said.
