Diaz went 2-for-5 with a double, a triple and three RBI in Tuesday's 7-6 extra-inning win over the Red Sox.
He got the Rockies on the board in the third inning by rattling a bases-loaded double off the Green Monster. Diaz hasn't homered in 15 games, a stretch in which he's slashing just .186/.238/.288, but he has four extra-base hits (three doubles and a triple) through 10 contests in June with six RBI, and he remains locked into the starting role behind the plate for Colorado.
