Garrett went 1-for-2 with a grand slam in Tuesday's 10-5 loss to the Diamondbacks.
Though Garrett had been making most of his appearances as a pinch hitter lately, he received the start in left field Tuesday and gave the Nationals a 4-1 lead with a first-inning grand slam off Tommy Henry. The long ball was Garrett's second of the season, but his first since April 8. He has struggled to earn a steady role in Washington's outfield when the group is at full health but has benefitted from injuries to Corey Dickerson, and more recently, Victor Robles (back).
