Matt Harvey has left his start against Miami after seven innings with tightness in his lower back.
The New York Mets sensation singled in the seventh Saturday and appeared to run somewhat gingerly to second base on an inning-ending groundout. He warmed up for the eighth, but then there was a mass meeting on the mound that included a trainer, manager Terry Collins and the entire Mets infield.
Harvey finally gave up the ball - reluctantly, it appeared - and walked to the dugout. Brandon Lyon was given all the time he needed to warm up.
It was the eighth no-decision in the last nine starts for Harvey, who remains 5-0. He gave up one run and six hits, striking out six and walking none.
