Brown left Thursday night's game against the Yankees in the third inning due to soreness in his left Achilles, and he revealed that the tendon had been bothering him for several weeks.
Brown said he began to feel soreness in the area when he started chasing after Yankees third baseman Chase Headley's second-inning home run at George M. Steinbrenner Field.
"I want to be in there, Spring Training or not," Brown told reporters on Thursday night. "I feel pretty good at the plate. I don't want to miss any time, but this is part of the game, also. I'm definitely frustrated for sure. It seemed like we were going in the right direction, it was getting a little bit better."
Brown is hitting .241 (7-for-29) this spring. The Phillies are hoping for a bounce-back campaign from the 27-year-old, who hit .235/.285/.349 with 10 home runs last year after a breakout, All-Star 2013 season in which he hit .272/.324/.494 with 27 homers.
