Diaz went 1-for-3 with a grand slam and a sacrifice fly during Friday's 7-6 loss to Tampa Bay.

The catcher also recorded a season-high five RBI, shattering his previous record of two, which he accomplished multiple times. Over his last seven games, the 35-year-old is slashing .316/.364/.632 with one homer and seven RBI over 21 plate appearances.
