Alvarez went 1-for-5 with a solo homer in Friday's 3-2 extra-inning victory over Arizona.
The veteran slugger broke the ice on a dismal offensive performance up to that point by taking reliever Enrique Burgos deep with a 407-foot shot to right in the eighth, kickstarting the Orioles' comeback. Despite the homer Friday and some modest success making hard contact during the month, Alvarez is struggling overall in September, as evidenced by his .195 average over 41 at-bats.
