Diaz went 2-for-4 with a solo home run and a walk in a 5-2 win against the Tigers on Thursday.
Diaz led off the bottom of the first with a 438-foot bomb to center off Detroit starter Tyler Alexander, singled in the third and walked in the sixth to reach base three times for the third time in September. Despite the three excellent games, Diaz has just five hits across his other 11 games this month and is batting .230 with three doubles and two home runs for September.
