The game was decided in the first inning. Oakland scored twice on Carlos Cortes' triple and held that margin through nine innings to defeat Texas 2-1 at Globe Life Field.
Cortes carried the Athletics offense with a 3-for-4 performance that included the game's decisive hit. The outfielder is batting .377 with four home runs and 13 RBIs this season. Tyler Soderstrom and Brent Rooker both scored on his center field triple in the opening frame.
Texas managed only one run against Oakland's bullpen game. Jung scored on Evan Carter's sacrifice bunt in the sixth inning, with Carter reaching first on a throwing error by pitcher Lopez. The Rangers could not generate another scoring threat.
Kumar Rocker took the loss for Texas despite a solid effort, allowing six hits and two runs over six innings with three strikeouts. His ERA stands at 3.38. Oakland used four pitchers, with Justin Sterner earning the win and Jack Perkins recording his second save.
The victory snapped Oakland's losing streak and moved both teams to 14-13. Texas remains atop the division despite the defeat.
