No details on an injury were given. O'Brien is a non-roster invite who is battling for a spot as a bench bat on the Opening Day roster for the Braves, but faced an uphill battle even before the placement on the IL. 

O'Brien has three homers in 18 at-bats this spring, though that's not really anything new for him; he has 16 homers in 176 spring at-bats for four different teams the last four years. Making contact against major league pitchers is a huge problem for him and he doesn't have any defensive value, so it's likely that he's destined to spend another year in Triple-A.

O'Brien tagged Rays' starter Yonny Chirinos for the solo shot leading off the second inning -- increasing the Braves' lead to 4-0 at the time. It was hit lone hit in two at-bats on the day. For the spring, O'Brien is now hitting .273 (3-for-11) with a homer and two RBI.

O'Brien has received 200 big-league plate appearances over parts of four seasons but hasn't done much with them, hitting .209/.275/.434 with a 36.5 percent strikeout rate. He'll likely be an organizational depth option for the Braves this season.
