Alvarez went 2-for-4 with an RBI double and solo homer in Friday's 4-3 victory over the Rays.
His 433-foot solo shot in the third opened the scoring for the Orioles, and his run-scoring two-bagger in the fifth plated J.J. Hardy to close Baltimore's deficit to 3-2 at the time. The 29-year-old is swinging a hot bat in July, having sandwiched multi-hit efforts around the All-Star break and slashing .500/.875/1.375 over his first 16 at-bats of July with three doubles, Friday's homer and two RBI.
