The call ultimately didn’t cost the Red Sox, who went on to beat the Mariners 3-2 in 10 innings on a walk-off double by Rafael Devers, but Boston could have potentially won earlier had it not been for a controversial interference call that ended the bottom of the seventh.

With the score tied 2-2, one out and men at the corners in the bottom of the seventh, Devers stepped to the plate with a chance to put Boston ahead. Devers wound up popping out to the right side of the infield, but as the play unfolded the runner at first, Tyler O’Neill, made contact with Mariners first baseman Justin Turner.

The ball wound up being caught by the second baseman, but O’Neill was called for interference anyway, which resulted in an inning-ending double play.

Following the game, Red Sox manager Alex Cora said he’s still seeking clarity from the league on what exactly happened.

“The runner has to give the fielder a chance to catch the ball, first of all (Turner) didn’t catch the ball, the ball was at second base, but we’ll see. I’ll probably explain it on Friday because I want the league to take a look at the play and how it developed and go from there,” Cora said. “I was telling (umpire Andy Fletcher), if we want Tyler to avoid the fielder how do we accomplish that? Because he’s going back to the bag, he’s looking at the ball, JT, I don’t know if the intention was going straight into the runner or if he was actually going for the fly ball.

“If he goes to the grass and they drop the ball he’s going to be out, if he goes to second they drop the ball he’s going to be out. It’s hard to become invisible,” Cora continued. “But we’ll wait, they’ll explain it and we’ll try to explain it to our players.”

Cora went on to explain that the infield fly rule was in effect for the play, which impacted the situation as well, but O’Neill expressed confusion over the ruling and what he should have done differently.

“I went through my secondary and took one step back and had Turner under my elbow bodying me around a little bit. I was a little surprised by the ruling, not too sure what happened there honestly,” O’Neill said. “I don’t know what else I could do honestly, I took a step back towards the bag, I wasn’t making an effort to get in anyone’s way, I didn’t think there was anyone going to be in the way to begin with so it definitely felt like there was some intent there.

“That’s tough luck but it wasn’t even Turner’s ball, he didn’t end up catching it, so I don’t know,” O’Neill continued. “Andy Fletcher the umpire said it’s a new rule from MLB so I’m not too sure how that works. MLB is able to just flip the switch on us and switch some rules up, so it’s up to us to keep up to date with those, but I don’t know.”

The call would have been much tougher to swallow had the Red Sox gone on to lose the game, but instead the club will enjoy an upbeat flight to Texas for the start of this weekend’s road trip, by which point it shouldn’t matter too much what kind of explanation they wind up getting from the league office.
