Marcus Semien hit a tiebreaking homer on the first pitch of the ninth inning and the surging Oakland Athletics went on to their third straight victory, 9-4 over the Texas Rangers on Monday night.
The Athletics (12-11) have won seven of eight, and have a winning record for the first time since they won their season opener before a three-game losing streak.
Semien's third homer of the season, off Kevin Jepsen (0-3), snapped a 3-all tie and ignited a six-run outburst. Matt Chapman had an RBI triple with two outs, then after a pitching change scored on a single by Mark Canha before Jake Smolinski hit a two-run triple.
Ryan Buchter (1-0), the fourth of five Oakland pitchers, retired the only two batters he faced -- the last out of the eighth and the first out in the ninth.
The Rangers, who are 3-11 at home this season, tied the game in the fourth when Jurickson Profar drew a two-out walk from Trevor Cahill and Robinson Chirinos followed with his third homer of the season.
Khris Davis had a two-run double in the third to put Oakland up 2-0, giving him 21 RBIs this season. Chad Pinder's RBI single an inning later made it 3-1.
Rookie second baseman Isiah Kiner-Falefa, the Rangers' No. 9 hitter, doubled in the third for their first hit and scored on a wild pitch.
Both starting pitchers allowed three runs over five innings. Rangers lefty Matt Moore, who was pulled after giving up a leadoff single in the sixth, struck out two and walked two. Cahill, who threw seven scoreless innings in his only other start this season for the A's, had six strikeouts, two walks and the wild pitch that allowed a run.
Rangers: RHP Doug Fister (right hip strain) felt good a day after throwing a bullpen and is set to come off the disabled list to start the series finale Wednesday.
Rangers lefty Cole Hamels (1-3), trying to avoid four losses by the end of April for the first time in his career, has lost four consecutive home starts -- including both this season. Right-hander Andrew Triggs, with a 1.02 ERA in four career appearances against Texas, starts for the A's in the middle game of the three-game series.
