Justin Verlander thinks his rough outing Monday against the Mets will serve as a positive in the future.

Verlander said he taxed himself in a bullpen session a few days ago and didn't feel right before facing the Mets at Joker Marchant Stadium.

Verlander gave up four hits -- including two home runs -- and two walks in 4 1/3 innings. He also hit two batters, and he allowed five earned runs in an 11-0 loss.

"I worked really hard in my last bullpen (session), kind of the first time this year that I really grinded in my bullpen and got after it," Verlander said. "I kind of felt that ran over into this start. Just didn't feel fresh. That's an adjustment, too.

"In season, there's going to be times where I want to go in the bullpen and work on stuff and kind of tax myself. I need to be able to respond. I think it's a good thing that I was able to do that this time and get my body accustomed to it. Hopefully next time I do it and I feel great."

Verlander gave up a leadoff home run to Jordany Valdespin.

Verlander was called for a balk that scored another run in the second before giving up a home run to Brandon Hicks on a fastball.

Verlander was one pitch over a 60-pitch limit when he left in the fifth, after hitting Valdespin in the groin. Valdespin had squared around to attempt a bunt and dropped facedown in obvious pain.
