Baldelli, who has been showing up at Tropicana Field for home games, went 1-for-5 as the team's designated hitter.
Baldelli, 26, is on the 60-day disabled list with a mitochondrial disorder, an abnormality that has kept him in a constant state of fatigue. The Rays have not set a timetable for Baldelli's return, but earlier in the week he expressed hope for a return this season in some capacity.
Baldelli has not played in a Major League game since last May. He has a .282 career average in four Major League seasons with 48 home runs and 221 RBIs; he hit .204 with five home runs and 12 RBIs in 35 games in 2007.
