Swanson went 1-for-2 with a solo home run in Wednesday's Grapefruit League game against the Rays.
The shortstop turned on a Shane McClanahan pitch in the second inning and drove it completely out of CoolToday Park. Swanson delivered a career-high 27 homers and 88 RBI last season, and the 28-year-old will be counted on to supply similar or better numbers for Atlanta in 2022 as the club looks to repeat as World Series champions.
