OAKLAND -- Manager Mike Scioscia could only shake his head after watching the Angels endure their most lopsided loss in franchise history, a 21-3 thrashing at the hands of the A's on Thursday afternoon at the Coliseum.
"Turn the page," Scioscia said. "We were out of this one early, and it kept getting worse."
Stephen Piscotty's three-run home run off right-hander Matthew Shoemaker capped a five-run third inning for the A's, who continued to widen the gap by scoring seven runs in the fourth and six in the sixth against the Angels' bullpen.
After the deficit ballooned to 16, the Angels sent catcher Francisco Arcia to the mound in the bottom of the seventh for his second pitching appearance of the season. Arcia yielded back-to-back home runs to Nick Martini and Chad Pinder that extended Oakland's lead to 21-2, but he came back to post a scoreless eighth and then launched a solo shot off Chris Hatcher in the ninth, becoming the first player to catch, pitch and homer in an MLB game.
"I just try to stay positive and just play hard all game," Arcia said. "I feel good about it."
The 21 runs tied the franchise record for most runs allowed by the Angels in a game, an ignominious mark that also occurred on Sept. 30, 2000, against Seattle.
After rallying to win Tuesday's opener, the Angels were outscored by the A's, 31-3, in the final two games of the series. Each member of Oakland's starting lineup finished with at least one hit and one run scored on Thursday.
Michael Trout launched his 36th home run of the season and Jose Fernandez delivered an RBI double to account for the Angels' other two runs of the afternoon.
Shoemaker lasted only 2 2/3 innings for the Angels and departed after yielding five runs on five hits. The 31-year-old right-hander opened his outing with two scoreless innings before unraveling in the third.
Josh Phegley and Martini led off the inning with back-to-back singles, setting up Matt Chapman's two-run double to left field. Jed Lowrie then singled to put runners on the corners, but Shoemaker came back to strike out Khris Davis and Matt Olson to bring up Piscotty with two outs.
Shoemaker couldn't avoid more damage, however, as he misplaced a 1-1 slider that Piscotty crushed to left-center field for a three-run shot that gave the A's a 5-1 lead. With his pitch count at 63, Shoemaker was subsequently lifted in favor of Jim Johnson.
"It was pretty atrocious, to be honest," Shoemaker said. "I can deal with them putting a few singles together. That's going to happen. The frustrating part -- kind of similar to last time against the Mariners -- was I battled to two outs and then made a bad pitch. If I get that guy out there, I can live with giving up a couple runs."
Shoemaker has now allowed 11 runs over 17 1/3 innings (5.71 ERA) in four starts since returning from a right forearm injury that sidelined him for five months. While Shoemaker's health issues appear to be behind him, he's still in the process of recapturing his form after missing a significant chunk of the season.
"He's trying to get back his game at the Major League level because he missed most of the season, so there's going to be some rough spots here or there," Scioscia said. "He's at times pitching very well, and at times, he's missing his spots, getting behind and making mistakes. But the stuff is there, no doubt. Maybe the command isn't as consistent as we know it can be with Matt."
The Angels will head to Houston and kick off their final road series of the season against the Astros on Friday at 5:10 p.m. PT. Left-hander Andrew Heaney (9-9, 3.97 ERA) will oppose right-hander Gerrit Cole (14-5, 2.88 ERA in the series opener. Heaney did not factor into the decision in his last start on Saturday after giving up two runs over five innings against the Mariners. He is 3-1 with a 1.95 ERA in six career starts against the Astros.
