ARLINGTON -- One rough inning can change everything.

It happened to Noah Syndergaard on Monday when a close ballgame turned south fast and it happened again to reliever Ryan Tepera on Tuesday at Globe Life Field in what would be a seven-run rally for the Rangers.

“Let’s say it’s one I’m going to forget,” Tepera said following the 10-5 loss. “It just kind of spiraled out of control.”

For a moment, it looked like Mike Trout would be the hero when he launched a solo home run in the seventh inning to give the Angels the lead. Trout had been on a roll and he was a triple shy of hitting for the cycle. But when the Rangers came up in the eighth, the game spiraled out of control.

It marked the second straight game that the Angels allowed six-plus runs in an inning. Trailing 4-3, the Rangers plated seven in the eighth to hand the Angels their first series loss since late April.

Five of those runs came off of Tepera. Two were charged on the mound and the other three scored after he was pulled from the game.

“I just did not want to stay with him any longer,” Angels manager Joe Maddon said. “It’s just a really awkward, unfortunate inning.”

The first run of that inning came home on an RBI infield single from Rangers outfielder Adolis García. Second baseman Luis Rengifo managed to snag the ball, but the throw ended up glancing off first baseman Matt Duffy's glove and hitting him near his right eye as García crashed into Duffy.

It was all downhill from there. Duffy exited the game with a cut under his eye that was beginning to swell by the time he made it to the clubhouse. He said he was fine after the game.

After Reid Detmers (making his first start since his no-hitter on May 10) allowed a first-inning homer to Corey Seager, the Angels took a 3-1 lead in the third thanks to a solo homer from Taylor Ward and a two-run shot from Anthony Rendon. But Detmers was unable to hold the lead as he gave up a two-run dinger to Kole Calhoun in the fourth inning. After that homer, Maddon decided his starter's night was over.

“He just wasn’t sharp. He wasn’t sharp at all. Probably [the] fastball was his best pitch tonight. He wasn’t landing the curve as well, or the change-up,” Maddon said. "It’s one of those things I say to myself, I tell [pitching coach Matt Wise], ‘It’s just not gonna work,’ and you’ve got to move it along.”

The Angels will look to avoid being swept for the first time this season in Wednesday's series finale.
