Travis d'Arnaud asked to play against the Pirates on Sunday despite catching 14 innings the night before, Mets manager Terry Collins said.

The results were mixed.

D'Arnaud went 2-for-3 with a double and his sixth home run in the Mets' 8-1 loss. The homer tied the score at 1 in the second inning.

But in the seventh, which began with the score tied, d'Arnaud's passed ball allowed pinch runner Sean Rodriguez to score. That gave the Pirates a 3-1 lead, and by the time the inning was over, the Mets trailed 5-1.

"He probably was exhausted from last night," Collins said. "He hit a homer, hit a double, I think it was pretty good."

And as for the defensive gaffe? "He missed it," Collins said. "Humans."

D'Arnaud said it was hard to recover from Saturday's long game but joked that the clubhouse espresso machines gave him the boost he needed.

It was his fourth career game with multiple extra-base hits and second this season. But d'Arnaud downplayed his personal success, focusing on the lopsided outcome and his passed ball.

"I should have caught that ball," he said. "That's 100 percent my fault. I just took my eye off it. I try to do whatever I can to help the team win every single day, and I was hoping to get a win today as well."

D'Arnaud has played only 31 games this season. He suffered a fractured right pinkie April 19 and did not return until June 10. Then he sprained his left elbow June 20 and did not return until July 31.

"Coming out there and hitting a home run like he did and getting that double, it's positive when he's back and he's playing," said Matt Harvey, who started for the Mets.

"He's going to get a new groove and start hitting balls hard like he normally does," Harvey said. "It's just a matter of him being in the lineup and playing every day. He's going to get back to his normal self, and it showed today."
