What looked like a certain out turned into a run-scoring hit in Oakland on Thursday.

Red Sox outfielders Jackie Bradley Jr. and Mookie Betts converged on Stephen Piscotty's fly ball to the right-center-field gap in the fourth, but instead of going for an inning-ending out, it landed in between the Gold Glovers.

Bradley looked at Betts, who also looked at Bradley, and then both realized before it was too late that the ball was going to drop.

With that, Piscotty's fly ball went for a ground-rule, two-run double, and the A's had a 6-3 lead. Oakland would go on to win, 7-3.

“It’s on me,” said Bradley. “It’s a play that has got to be made. I’m the leader out there. The play has to be made. It’s a catchable ball. I’ve got to take control.”

Betts also took accountability.

“Oh, one of us should have caught it,” Betts said. “Just one of those things, right dead in the middle. One of us should have talked for sure. I mean, I think for any outfield, that ball is catchable. It’s just one of those things, it happened. There’s nothing you can do about it. Just know going forward that somebody needs to say something.”

Red Sox manager Alex Cora didn’t point fingers at either outfielder, but he noted communication needs to improve.

“The whole game, it was an issue,” Cora said. “I pay attention to details. I love paying attention to details, and that’s something I took pride in last year. And right now, we’re not paying attention to details.

“So, that’s on us. That’s on me. That’s on the staff. I know they have made mistakes. But at the same time, I think it gets to a point that we have to keep teaching the game and putting them in spots that they’re going to take advantage of certain situations.”
