SAN DIEGO -- Light-hitting Franklin Barreto connected for a 424-foot, three-run home run, one of five long balls the Oakland Athletics hit in routing the San Diego Padres 12-4 on Wednesday.
The A's hit seven homers in sweeping the two-game series. Stephen Piscotty tied Tuesday night's game with a homer with two outs in the ninth off Brad Hand and Lowie hit a two-run shot with two outs in the 10th for a 4-2 victory.
Barreto and Phegley went back-to-back with their first homers of the season in the second inning off left-hander Joey Lucchesi (3-3), who had been on the disabled list for more than a month. Barreto, hitting .071 coming in and batting seventh, homered into Oakland's bullpen well beyond the fence in center field on a full-count pitch. Phegley homered off the Western Metal Supply Co. brick warehouse in the left field corner on a 1-1 pitch. Lucchesi hit Olson with a pitch opening the inning and then walked Piscotty ahead of Barreto's homer.
Robbie Erlin got the last out of the second before allowing consecutive homers to Canha and Olson in the third. It was Canha's ninth and Olson's 15th. Phegley added a sacrifice fly.
Lowrie connected off Phil Hughes in the eighth, his 11th.
Frankie Montas (4-1) benefited from the long balls as he threw 6 2-3 strong innings. He held the Padres to one run and five hits, struck out six and walked three. He allowed Cory Spangenberg's RBI single in the third.
Lucchesi went just 1 2/3 innings, allowing four runs and three hits.
Trailing 10-1, the Padres had infielder Cory Spangenberg pitch the ninth. He allowed two runs on two hits and two walks in his second appearance of the season.
San Diego's Christian Villanueva homered in the ninth, his 16th.
Padres: Placed RHP Bryan Mitchell on the 10-day disabled list with an impingement in his right elbow to make room for Lucchesi on the 25-man roster. Mitchell (0-3, 7.08 ERA) hasn't pitched since June 5. Mitchell has been disappointing since being acquired from the New York Yankees along with third baseman Chase Headley. The Padres wanted Mitchell so badly they were willing to take on Headley's $13 million salary, but the deal has backfired. Headley was released on May 19 and Mitchell was demoted from the rotation to the bullpen.
