Rangers rough up A’s rookie early, take Game 1 of DH

Rougned Odor belted right-hander Daulton Jefferies’ 20th major-league pitch for a three-run homer and Ronald Guzman added a two-run shot two batters later Saturday afternoon as the Texas Rangers scored five first-inning runs and made them hold up for a 5-2 victory over the visiting Oakland Athletics in the first game of a doubleheader.The first-place A’s (28-16) were scheduled to send right-hander Chris Bassitt to the mound in the nightcap to oppose Kolby Allard of the last-place Rangers (16-29).The win was just Texas’ second in eight head-to-heads with Oakland this season.The 25-year-old Jefferies walked two of the first four men he faced before Odor took him deep to right field for his fifth homer of the season and a 3-0 lead.After Elvis Andrus followed with an infield single, Guzman then crushed his third homer of the season to right, making it 5-0.Jefferies (0-1) pitched a scoreless second inning, allowing one hit, before getting pulled. He was charged with five runs on five hits in his two innings, with two walks and one strikeout.After going down 1-2-3 in the first inning against Rangers opener Nick Goody, the A’s chipped away at the Texas bullpen, scoring once in the third on a Jonah Heim single, then once in the sixth on an RBI double by Matt Olson.But Oakland mustered just four total hits off Rangers relievers Wes Benjamin (1-0), Jonathan Hernandez and closer Rafael Montero, with the latter working a 1-2-3 seventh for his eighth save.
