Aguilar went 3-for-5 with a double and a three-run home run in Saturday's Grapefruit League game against the Cardinals.
Getting the start as the designated hitter and batting fifth, Aguilar crushed a Steven Matz offering to straightaway center field in the first inning to kick off a big day at the plate. The 31-year-old slugger racked up 22 homers and 93 RBI over 131 games last season with a .788 OPS, and he figures to be a dependable middle-of-the-order presence for Miami while splitting his time between first base and DH.
