"I don't know what it is," Morrison said after the Marlins improved to 4-0 in games started by Harvey this season with a 3-0 win Thursday afternoon. "We do it to [Stephen] Strasburg, too, sometimes."

Mets manager Terry Collins offered a theory.
"They don't strike out," Collins said about Miami. "The teams with big swingers, the teams that have a lot of power, that are a little bit more aggressive, they swing and miss. These guys don't swing and miss much. They put the ball in play and hit the ball to all fields. So they're a little tougher for him."
Harvey took a scoreless effort into the sixth inning, so it was not a poor outing. But in that frame, Morrison had a two-out RBI single, Ed Lucas was hit by a pitch and Donovan Solano followed with a two-run single that chased Harvey.
"You could tell he was getting tired," Morrison said. "But his stuff was still there. Maybe he was missing location a little bit."
On the nine-pitch at-bat to Solano that ended with the two-run single, Harvey said: "I couldn't make a pitch to get him out. When I went in, it wasn't in enough or down. And then I threw him a slider and it was up, so he shot it to right field."
Collins suggested Harvey's pitches were not as sharp in the sixth, as his pitch count crossed 100, because Harvey expends so much energy early in games.
Collins would prefer more groundouts earlier in counts on 93 mph pitches than Harvey dialing it up repeatedly to 98 mph and getting strikeouts.
"You could see the balls start to come up against him," Collins said about the Solano at-bat in the sixth. "He threw him two or three sliders that didn't have much depth to them.
"That's what we're trying to get him to certainly understand: If he throws so hard and has to work so hard, if he gets some easy outs early in the game, he'll be much better off."
Still, Collins added: "He certainly deserves a better fate than what he's had. He's pitched great. We just don't score many runs."
Harvey's three shortest starts this season have come in Miami, and they are the only three outings in which he has failed to complete six innings.
"It's not like I take this team any different than any other team," Harvey said. "It's just been that team this year that happens to squeeze out some runs. I'm not going to change my approach or do anything differently."
