Minor leaguer Garabez Rosa singled to drive in the tying run with two outs in the bottom of the ninth inning as the Orioles salvaged a 4-4 tie with the Atlanta Braves to remain unbeaten in their last six Grapefruit League games.
Rosa, who has made the most of playing in major league games this spring, is 9-for-17 with seven RBIs.
The Orioles are 5-0-1 in their last six games.
Two of the Orioles' four runs came on solo homers by third baseman Manny Machado and catcher Matt Wieters.
