Harvey entered Wednesday's start with 146 innings split between the Majors and Triple-A, after throwing 135 2/3 in the Minors last season. General manager Sandy Alderson previously pegged Harvey's innings limit at 165-170 for his second professional season, though manager Terry Collins said Wednesday that the rookie may not necessarily make it that far.
"I've had a lot of conversations with Matt, and he feels great," Collins said. "One of the things about the Minor Leagues is they monitor your workload a lot. They really keep an eye on it. They don't stretch it out and that's just the way the game is. It's changed at the Minor League level a lot, too. These guys are kept under control of their work, how much they throw. So I think there's probably some innings left in Matt, and that's why he feels so good. But I also know pitching in the big leagues has brought some energy to him, too."
A conservative estimate would have Harvey making three more starts, counting Wednesday's effort in Philadelphia, before he reaches his limit. A more aggressive guess would have Harvey making four.
Either scenario would force the Mets to shut Harvey down sometime in mid-September, two or three weeks before the end of the season. It is all part of a plan to keep his arm in shape for next year, in which Harvey should approach 200 innings for the first time in his professional career.
"Does seven innings make a lot of difference? Maybe not," Collins said. "But next year, when we're sitting there saying, 'OK, we'd like to add 35 or 40 innings onto what he did last year,' all of the sudden that seven innings could make an impact."
Even after they shut down Harvey, the Mets may proceed with a six-man rotation. September callups Collin McHugh and Jenrry Mejia will both receive starts down the stretch, and R.A. Dickey should extend the rotation by continuing to start every fifth game.
