NEW YORK -- Jacob deGrom and Matt Harvey will go through this together in their own ways, working on their issues and trying to return to the form that took the New York Mets to the World Series a little more than half a year ago.

Harvey noted in a video interview shown on the scoreboard before the game that deGrom is his best friend on the team; the two are linked by their on-field activities and high-caliber performance. Their numbers might be a little different (deGrom’s ERA is nearly three runs better than Harvey’s), but their current struggles seem to be a new common bond.

The Mets' 2015 postseason run is having after effects, even as the team rallied to beat the Milwaukee Brewers for the second straight day, this time on David Wright’s team-record eighth career walk-off hit.

DeGrom fought through five innings, pairing what matched his shortest outing of the season with a season-high four runs allowed. He also walked three for the second straight game. He never had such a streak in 2015.

The Mets rallied from 4-1 down to win thanks to Wright, as well as four innings of good relief work from Hansel Robles, Addison Reed and Jeurys Familia, and Yoenis Cespedes’ game-tying homer. That saved deGrom from taking an L along with his struggles.

“I’m working on some things,” deGrom said. “I feel like I’m getting better. It’s a work in progress.”

That’s not what you usually hear from deGrom on an afternoon such as this, in which he was pitching against a Brewers lineup missing its best hitter, Ryan Braun. DeGrom entered the day with a 1.03 ERA in 10 day-game starts at Citi Field, but this was a game in which even a sub-.200-hitting No. 8 hitter, Ramon Flores, made good contact against him, hitting his first career homer and driving in three runs.

DeGrom is allowing hard-hit balls in 20 percent of at-bats against him. That’s about double his rate from last season. He has gone from ranking among the 10 best pitchers in that stat to ranking among the 15 worst. His ERA looks good at 3.07, but his xFIP (which predicts future ERA based on strikeouts, walks and fly balls allowed) still stands at 3.97.

DeGrom cited fastball command and a mechanical flaw causing him to rush to the plate as the source of his issues. He did average 94.5 miles per hour with his fastball in the first inning, numbers in line with 2015, though that dropped to 93.2 over the next four. For the season, his average fastball velocity is down about two mph from last season, as noted in the chart on the right.

“Some days you have bad days, some days you have good days,” deGrom said. “It’s part of the game.”

But there’s still a ways to go.

“One hundred pitches is not Jacob deGrom, not even close,” Mets manager Terry Collins said. “What makes this guy successful is strikes down in the zone. Today, he had a lot of balls up in the zone. He was a little bit out of whack and we’ve got to get that corrected. This guy is too good a pitcher to throw that many pitches. We’re trying to work those guys who pitched all those innings last year and get them back in sync.”

There is confidence from those around baseball that deGrom is the most well-suited of the Mets' big four starters to pitch without premium fastball velocity. Baseball Tonight analyst Dallas Braden agreed.

“If that [losing two mph off his fastball) happened to me, I’d have been bagging groceries a long time ago,” Braden said. “He seems to be the most polished of the group, so I think he has a great chance to learn to ‘pitch.’ It may just be a matter of him getting comfortable with the idea of pitching to contact with his heater.”

Harvey got rocked for nine runs his last time out against the Washington Nationals, whom he’ll face again on Tuesday. Harvey didn’t talk to the media either before or after the game but did throw a 25-minute live session on the mound, pitching to reserve infielder Matt Reynolds and first-base coach Tom Goodwin. Harvey's fastball velocity has been down as well; at 94 mph for the season compared to 96 mph in 2015. His stellar slider, against which opponents hit .151 last season, has yielded a .385 opponents’ batting average in 2016.

“He looked very good,” Collins said. “We didn’t have a radar gun out, but we had Trackman (a system that logs things such as release point and pitch movement) working. His velocity was better. His arm angle, which he’s been working on with Dan [Warthen], was better. He’s confident and feels good about what happened today.”

The bigger question is -- will those good feelings last into the next time out? Not just for Harvey, but for deGrom as well.
