ARLINGTON, Texas (AP) — Trey Mancini had a tiebreaking RBI double in the eighth inning and the Baltimore Orioles scored off three Texas relievers in a 6-1 win. The bullpen faltered after Rangers rookie starter Dane Dunning threw six scoreless innings. Mancini’s double put the Orioles up 2-1 off loser Joely Rodriguez in his season debut. Freddy Galvis finished 4 for 4 for Baltimore, and Maikel Franco homered. Dunning has thrown 14 consecutive innings without giving up a run. Travis Lakins was the winning pitcher.
