Polanco (arm) served as the designated hitter in a minor-league game Tuesday, LaVelle E. Neal III of the Minneapolis Star Tribune reports.
Polanco has been battling arm fatigue, but he's been able to take at-bats in minor-league games each of the past two days. The shortstop also took part in some fielding drills Tuesday, which bodes well for his status for Thursday's season opener against the Indians. That said, the Twins will reevaluate Polanco on Thursday before determining his availability for the start of the season.
