BALTIMORE (AP) — Ryan Mountcastle and Austin Hays homered, rookie Zac Lowther pitched five sparkling innings to earn his first major league victory and the Baltimore Orioles beat the Texas Rangers 3-0. After going winless with a 9.61 ERA in his first six appearances, Lowther got into a rhythm against the light-hitting Rangers in this matchup of last-place teams. Lowther allowed three hits and notched a career-high seven strikeouts in his finest outing as a big leaguer. Tyler Wells worked the ninth to complete the five-hitter and earn his fourth save.
