One obvious factor in the team’s season-best, seven-game winning streak is rookie Michael Harris.

Harris gave Atlanta the lead with a two-run triple in the fifth inning that spoiled Jared Koenig’s major league debut, and the surging Braves beat the skidding Oakland Athletics 13-2 on Wednesday night.

A sellout crowd of 42,075 gave Harris an ovation, and his clutch swing triggered an outburst of extra-base hits that included four homers.

Anderson pitched six solid innings and the Braves rallied from a 2-0 deficit for the second straight night to sweep the two-game series.

Harris has impressed with his big defensive plays in center field, and he showed his offensive potential with a triple and double on Wednesday night.

The 28-year-old Koenig led 2-1 through four innings after completing his long path to the majors that included spending the 2017-19 seasons in independent leagues. The 6-foot-5 left-hander didn’t get an out in the fifth.

Harris was safe on a headfirst slide into third base. With two outs, Austin Riley’s two-run homer off Domingo Acevedo extended the lead to 5-2.

Albies’ three-run shot, which barely cleared the left-field wall over the glove of a leaping Chad Pinder, and Duvall’s two-run drive were the big hits in a seven-run seventh.

Harris added a seventh-inning double, complete with another headfirst slide into second base. He scored on Riley’s single for a 7-2 lead.

Ramón Laureano doubled and scored on a wild pitch and Sean Murphy had a run-scoring single in Oakland’s two-run fourth.

Koenig became the 20th rookie to play for Oakland this season, one shy of the team record set in 2008. He is the 13th rookie pitcher for the A’s, which sets a team record.

The A’s optioned right-hander Domingo Tapia to Triple-A Las Vegas when Koenig was recalled from Las Vegas. Right-hander Gabe Klobosits was designated for assignment.
