Zack Wheeler departed Monday night’s game after just two innings.

It was the second time in as many starts Wheeler was lit up like a Christmas tree and was chased from the game alarmingly early.

In Wheeler’s last go around, Wheeler lasted just 1 2/3 innings against the Chicago Cubs, allowing eight runs.

This seemingly came out of nowhere, as before the last to go around’s, Wheeler hadn’t allowed more than three runs in a start since April 23.

“It’s really frustrating. These last two outings weren’t very fun,” Wheeler said. “I haven’t  [had] my off-speed all year and now it’s starting to catch up with me. Guys get reports and it’s starting to catch up to me.”

The first five batters of the game hit Wheeler and hit him hard. The offensive barrage was topped off in the first inning by a three-run homer off the bat of Cody Bellinger, which sunk the Mets into an early 4-0 hole.

Wheeler retired the next three batters of the inning, but in the second, former Met Justin Turner and Bellinger went back-to-back to give Dodgers ace Clayton Kershaw a commanding 7-0 lead.

“The velocity was there, he hit 96 a couple times today, so the velocity is good but I do see a different breaking ball from him,” manager Terry Collins said. “His breaking ball wasn’t as sharp.”

Collins added that Wheeler only threw one changeup in the first, which is a pitch the starters haven’t been utilizing fully.

“Tonight in the first inning, he threw one changeup,” Collins said. “We’ve discussed before with our power pitching, the change up is a great pitch for those guys and they are not using it.”

The cat with nine lives, Rafael Montero, came on to relieve Wheeler in the third and delivered his second straight strong appearance.

Montero allowed just one run in 3 2/3 innings and didn’t just save the bullpen, but gave the Mets a chance to get back in the game.

Kershaw didn’t bring his A-game on Monday, serving up four home runs to Mets hitters, a career high.

But unfortunately, when you allow seven runs in a game, you seldom come away with a victory.

For Montero, the pitcher who has left fans wanting to pull their hair out for years, is actually starting to look like the pitcher he was supposed to be.

Since rejoining the Mets on June 15, Montero has appeared in two games, allowing just one run on 6 2/3 innings. He also delivered a three inning relief appearance against the Cubs last week.

As for Wheeler, its cause for concern as to why the pitcher has struggled since starting his season so strong.

Wheeler missed two years after undergoing Tommy John Surgery prior to the 2015 season, but said he felt fine and doesn’t feel fatigued.

“My command of all my pitches,” Wheeler said was the problem in Monday night’s 10-6 loss to the Dodgers. “Being able to throw offspeed for strikes, so they are sitting on fastballs. It is something I need to fix pretty quick.”

His innings limit has been a talking point all season, but now that Wheeler is struggling, the Mets are going to have to figure out what they choose to do with the starting pitcher going forward.
