Diaz went 2-for-4 with a walk and a two-run home run in Wednesday's 9-4 win over the Twins.
He took Louie Varland deep in the fourth inning, capping an eight-run eruption for the Rays offense. It's Diaz's 13th homer of the season, and third in his last six games as he catches fire for the home stretch. Over 28 contests since the beginning of August, the 33-year-old is slashing .294/.362/.461 with 12 RBI and 12 runs.
