Diaz entered Sunday's win over the White Sox on Sunday as a replacement for Ji-Man Choi (hamstring) and went 2-for-3 with a walk and a run.
Diaz reached safely multiple times for the second straight game, pushing his on-base percentage to an elite .361 in the process. The burly infielder is in the midst of a solid stretch of hitting, as he owns a .278/.333/.500 slash line with three doubles, three home runs and six RBI over his last 15 games.
