JUPITER, Fla. — Matt Harvey bleeds just like the rest of us.

After dominating the Tigers in his return to competition last week, the Mets ace was mortal against the Marlins on Wednesday, allowing two runs on six hits with one walk and two strikeouts over 2²/₃ innings.

Harvey’s fastball hovered around 95 mph, and he was removed after 49 pitches, following a strikeout of Michael Morse in the third inning.

“My body was a little sluggish, but other than that everything was fine,” Harvey said on a day the Mets lost 7-4 to the Marlins at Roger Dean Stadium. “I’m still getting in the swing of going out there multiple times and multiple innings, so getting the body in shape is definitely most important now.”

Harvey’s next outing is scheduled for Monday in Fort Myers against the Red Sox. The plan is to have the right-hander throw at least 60 pitches and go four innings.

There were no concerns on the Mets’ part about Harvey’s sluggishness Wednesday. Five days earlier, in his return after missing last season rehabbing from Tommy John surgery, Harvey pitched two perfect innings and topped out at 99 mph on the radar gun.

“I thought he was up in the zone a little bit more today, probably the adrenaline from the first game wore off a little bit,” pitching coach Dan Warthen said. “But outside of that I thought he threw the ball extremely well.”

Harvey also downplayed his “sluggish” feeling saying it probably should have been expected at this point in the spring.

“I think with being a little tired, a little sluggish, it got me out of my mechanics a little bit,” Harvey said. “But other than that everything felt great and I was happy that I was able to increase the pitch count and get up near 50 pitches.”

Harvey threw three sliders and two or three curveballs, according to Warthen, and used his changeup more than in his previous appearance.

Giancarlo Stanton’s inclusion in the Marlins’ lineup made for two anticipated showdowns. Harvey won the first battle, getting Stanton on a broken-bat line drive to third base. But in the third inning, Stanton unleashed a RBI double to deep left-center.

“It’s spring training, obviously you are working on stuff, but you get a guy in the box like [Stanton] and you’ve got to be a little bit careful not to leave the ball over the plate,” Harvey said. “But I felt that I gave him some good pitches and we had a good battle and he just got the best of me in the second at-bat.”

Harvey struggled an inning earlier, allowing three straight hits, including an RBI single to Ichiro Suzuki that pulled the Marlins within 2-1. Jarrod Saltalamacchia then walked to load the bases, but Harvey got Derek Dietrich to line into a double play.

Harvey faced just three batters in the first inning. Christian Yelich singled against him, but was picked off.

“[Harvey] looked all right,” manager Terry Collins said. “[Warthen] asked him to do a couple of things today and one of them was to throw more changeups, and he moved the ball around. I thought it was a good outing for him to come in and just get back in the swing of things in getting ready for the season and not worrying about trying to make a huge impact.”
