Robbie Grossman has been activated by the Twins, who also added pitcher Michael Tonkin to the team.

Grossman was reinstated from the 10-day disabled list and Tonkin’s contract was selected from Class AAA Rochester.

In other moves, the team put reliever J.T. Chargois on the 60-day disabled list, and removed pitcher Deitrich Enns from the 10-day DL and assigned him to Class AA Chattanooga.

Lefthanded starter Adalberto Mejia had his rehab assignment transferred from Rochester to Chattanooga. He has missed 25 games because of a left arm strain, and pitched in two games for Rochester, which did not make the International League playoffs.

Grossman, who had a fractured thumb, played two games in Rochester and was 1-for-7 with two walks. He is hitting .243 with seven home runs and a .363 on-base percentage for the Twins.

Tonkin pitched in nine games for the Twins earlier this season, then made 31 appearances in Rochester, where he had a 1.73 ERA in 41.2 innings.

Chargois suffered an elbow injury early in the season, and his transfer to the 60-day DL creates room for Tonkin on the 40-man roster.

Enns (left shoulder) and Mejia join the Lookouts for the Southern League playoffs.
