"Unfortunately, that happens," Tigers manager Brad Ausmus said.
Though Ausmus called the loss "embarrassing," he chose his words carefully with Gose. The fourth-inning mistake was a lack of awareness, not a lack of effort. The catch itself was actually an effort, with Gose sprinting toward the out-of-town scoreboard in right-center field to run down Josh Donaldson's drive just in front of the warning track with Ryan Goins on second base.
From there, however, Gose pulled up on the track and held onto the ball, clearly thinking he had recorded the third out of the inning. Goins, who was already prepared to tag up from second base, took off on the catch. Jays third-base coach Luis Rivera alertly waved him home before he could slow down.
By the time Gose realized there were just two outs, Goins was speeding home, saddling starting pitcher Buck Farmer with another run and giving Toronto a 6-1 lead.
"Most Major Leaguers do it at one time or another," Ausmus said of forgetting the outs. "A lot of times, you don't notice it, because there's no one on base. It rarely leads to a run. I've seen it happen before.
"It's not something you want to see. There's really nothing you can say to him. He knows he screwed up."
Gose was not available for comment after the game. Rajai Davis, Gose's teammate in Toronto and now again in Detroit, said he planned on talking with him.
"I think he knows, just to be aware," Davis said. "We can talk about it later. He knows he messed up. Everybody knows he messed up. He's not the first one to do that. He won't be the last. ...
"It's tough to stay focused when innings get long. It's tough to stay focused, and that's a quality we all deal with. Sometimes we're all looking to stay sharp. Sometimes we have a lapse. You don't like it. You don't want it to happen to you. You don't want it to happen to your teammates. But it still happens."
Asked if he can remember that play happening to him, Davis said, "I suppose I like to be sure. I'm looking in, just to make sure. If they say there's three outs, I'll play for four. I'd rather be sure than not. But it's still a learning game. We hope we learn from these mistakes that we make."
Making such a mistake in front of his old home fans likely didn't help. Gose played parts of three seasons in Toronto before the Tigers acquired him last fall for second-base prospect Devon Travis.
Gose singled in the fifth inning and walked in the eighth. He slid in hard on Troy Tulowitzki at second base to break up a potential double play in the eighth, drawing some boos from Jays fans on his way back to the dugout.
