BOSTON -- Rangers manager Bruce Bochy has often mentioned how small the margin of error is for a team when you’re struggling to put runs on the board.

The Rangers have definitely been struggling to put runs on the board. And with a banged up rotation, compounded by a banged up bullpen, the margin for error is incredibly thin. José Ureña made his third straight start on Tuesday night against the Red Sox at Fenway Park. For the third straight outing, he was tagged with the loss.

In Texas’ 9-4 loss on Tuesday night, Ureña battled through four innings of one-run ball before that margin of error got to him, as he allowed five runs in the fifth to extend Boston’s lead. A three-run homer from Connor Wong was the final dagger.

“We'll start out with bad luck,” Bochy said. “You have to look at how the ground balls got through, the blooper, then that set up that three-run homer. [Ureña] got [Rafael] Devers out. That was a big out. We had to give him some leeway with this bullpen situation. I liked the matchup there, but he just backed up a slider that left the ballpark and put it out of reach.”

But regardless of what Ureña did over that time, the Rangers’ offense didn’t give him much wiggle room either. Texas did not have a baserunner through the first 5 1/3 innings against Kutter Crawford, who was remarkably efficient during that time.

“Part of this game is getting calls and not getting bloopers falling in, which they had and we didn’t,” Bochy said. “They didn't hit it hard all the time, but the balls had eyes and that's been a tough part of this little streak we're in, I think. But it's no excuse. You still have to make contact, have to throw out good at-bats and for the first five innings tonight, we just couldn't throw out the quality at-bats and get some runners on.”

But then a Carson Kelly single opened the floodgates. Texas battled back, sending every batter to the plate in the sixth inning, and putting up four runs before a controversial strike three call on rookie Wyatt Langford halted the rally prematurely.

That ultimately led to Bochy’s 86th career ejection and his fifth this season after he quickly made his way to argue with home plate umpire Erich Bacchus between innings.

“We had the bases [loaded] and we created the situation that we were hoping for that could give us a chance to tie the game or take the lead,” Bochy said. “The pitch on Langford, this kid's gotten the bad end of those calls too many times. It's just gotten old. It's hard to tell from our dugout, but I know he was frustrated. That's why I went out there. I'm just tired of him getting the bad end of those calls. It's a big call. The bases were loaded, and it would have put a little more pressure on the pitcher, and the call went their way.”

Like Bochy said, Langford has been on the wrong end of a number of calls like that this season.

Among 285 players who entered Tuesday having seen at least 300 out-of-zone pitches that they didn't swing at, Langford had a called strike on 7.8% of them, the 28th-highest rate.

“I thought it was off [the plate],” Langford said. “Looking back, it was. And [catcher Connor Wong], I kind of thought he caught it pretty bad, too, so that kind of made the point even moreso. It's always frustrating, because there's nothing to do about it after the fact, even if it's wrong. I mean, it was close, I get it, but it sucks. Again, it’s frustrating.”

As for the offense’s continued struggles, the Rangers can’t seem to pinpoint the issue.

Texas recorded six hits and drew three walks on Tuesday, but stranded five runners on base, including the three from Langford’s bases-loaded strikeout. This is the second time in the last week that the Rangers have been no-hit through at least five innings.

“I guess you could call it pressing,” Langford said. “It's just tough. We can't seem to get it figured out on the offensive side. We’re just spotty every now and then. We'll come alive, then we'll stop. It’s definitely frustrating. So we’ll do what we can to figure that out.”
