Grandal went 1-for-2 with a solo home run and two walks in Tuesday's win versus the Pirates.
The catcher has been red hot since he returned from the injured list Friday, crushing four home runs and driving in 11 runs over four games. He has now launched 18 long balls this season, but Grandal has struggled to a .210 batting average, which would represent a career low for the 32-year-old.
