Biscuits outfielder Henry Wrigley has been promoted to Triple-A Durham and Charlotte's Ty Morrison has been sent to Montgomery.
Morrison had a .281 average with 14 RBIs and 15 runs scored in 32 games for the Stone Crabs. He was also 11-of-13 on steals. The 21-year-old was a fourth-round pick in the 2008 draft.
Wrigley, who was hitting .270 with seven home runs and a league-high 27 RBIs in 32 games this season for Montgomery, will be making his Triple-A debut. He's in his seventh year in the Tampa Bay organization and was in his third with the Biscuits.
The Stone Crabs have two outfielders on the disabled list. Kevin Kiermaier hasn't played since April 17 and Brett Nommensen has been out all season.
