​As expected, the Atlanta Braves have activated rookie outfielder ​Ronald Acuña Jr. from the disabled list after missing the last month with a ​knee injury that occurred back in Boston while running through the first base bag.

But that was just the beginning of the roster moves Atlanta made this afternoon.

The Braves also placed right-handed starter Brandon McCarthy on the 10-day disabled list with right knee tendinitis, which has come out of nowhere (yes, it's the knee, not the ​shoulder he dislocated earlier this season).

To make room on the active roster, Atlanta optioned right-handed pitcher ​Wes Parsons back to Triple-A Gwinnett after a day with the ballclub. To take McCarthy's spot on the pitching staff, the Braves immediately recalled right-handed pitcher Matt Wisler.

​​Wisler was just called up earlier this week and then sent back down, but because of the injury to McCarthy, he can return within the 10 days a player usually has to wait before they can be recalled to the big leagues.

With McCarthy slated to start on Saturday in St. Louis, expect Wisler to get the start.

The 20-year-old phenom Acuña, though, is a welcomed sight to an offense that has been up and down in recent weeks. Before landing on the shelf, the kid was hitting .265/.326/.453 with five home runs and 13 RBI.
