 ANAHEIM– It rained home runs at Angel Stadium on Tuesday night, but in the end, the Oakland Athletics fell 5-4 to the Halos – and back to last place.

 The game was tied at 2-2 after the fifth inning, but an error by A’s shortstop Marcus Semien allowed Angels third baseman Jefry Marte in the sixth inning to hit a homer on a fly ball to left and Mike Trout and Albert Pujols to scored, giving Anaheim a 5-2 lead.

 In the eight inning, A’s first baseman Yonder Alonso hit a homer on a line drive to right field and left fielder Khris Davis scored to put them within one of the Angels. But Oakland failed to score any more runs.

 “They got some home runs when they needed it, what ended up being the difference in the game,” A’s manager Bob Melvin said.

 Semien, who had not one, but two errors in the game, said Marte’s three-run homer made it all the worse.

“That would have been a solo home run instead, probably. I think we turn two if I catch it clearly, but of course it hurts,” Semien said. “I want to make every play I can. It just didn’t happen.”

 Oakland starting pitcher Sean Manaea didn’t let Semien take all the blame, saying the errors were “not really that big of a deal.”

 “I should have made better pitches to Marte,” Manaea said. “We try to go in and I just threw right down the middle – that was completely my fault. Marcus is going to get that ball next time. It’s one of the things that happens and just have to move on from that.”

 Prior to the decisive three-run homer, Manaea had a rhythm going, pitching changeups, fast balls and sometimes sliders.

 “Early in the game, he looked really good, like when we’ve seen him when he’s at his best,” Melvin said.

 In 5 2/3 innings, Manaea allowed six hits and five runs, four earned.

 The A’s took an early lead in the game when left fielder Khris Davis homered on a line drive to right center field in the second inning. It was his 27th home run of the season in the second inning, and he’s tied with Mike Napoli and Jedd Gyorko leading the Major League for most homers following the All-Star break at 8.

 “Seems like he’s more and more confident up there as the season goes along,” Melvin said of Davis.

 In the fifth inning, A’s left fielder Coco Crisp hit a homer on a line drive to right center field to put the A’s up 2-0.

 But Angels’ Jett Bandy hit a homer on a line drive to left field and Andrelton Simmons scored, tying the game at 2-2. It was downhill from there for the A’s.

 “Just got to get better the next day, that’s all you can do,” Semien said. “I still feel like I’m in a better spot when I’m out there. Just today was bad.”

With their fourth straight loss, the A’s, 47-59, sit in last place in the American League west. First pitch for the second in the three-game series at Angel Stadium is 7:05 p.m. Wednesday.
