OAKLAND, Calif. -- Khris Davis hit a go-ahead homer leading off the seventh after his tying solo shot in the fourth, and the Oakland Athletics beat the Texas Rangers 3-1 on Friday night.
Kendall Graveman (4-4) struck out six and didn't walk a batter in seven innings, improving to 3-0 at home in his fifth start back from a stint on the disabled list. He allowed one run and nine hits.
Davis notched his 15th career multihomer game and fourth this season with Nos. 35 and 36 of the year, then Matt Chapman added an RBI single insurance run in the seventh.
Adrian Beltre hit an RBI single in the first before Davis' one-out drive in the fourth tied it.
Blake Treinen -- Oakland's second reliever following a scoreless inning by Chris Hatcher -- finished the 2-hour, 26-minute game for his sixth save since coming to the A's in a July 16 trade with the Nationals.
Right-hander Nick Martinez (3-5), called up from Triple-A Round Rock to make the start, struck out seven with two walks in seven innings and allowed three runs and four hits.
This marked the AL West clubs' first meeting since the Rangers swept a three-game series at home from May 12-14 and the initial meeting of 10 remaining games between the teams. That includes two of the season's final three series and a four-game set to conclude the year.
