This spring has undoubtedly belonged to Domonic Brown. Brown is hitting .400 with three home runs, including a 2-for-4 day at the plate in Thursday’s 10-6 loss to the Twins. Brown looks more confident at the dish, something Phillies manager Charlie Manuel and many others have noticed. He finally appears to be the feared hitter he was supposed to be when he debuted in 2010. But Brown’s maturation has been more than just a tweak in his approach at the plate. His reputation as an outfielder had been average at best. Yet, there was Brown on Thursday, darting across left field to track down a hard-hit ball, turning what should’ve been a double into a single. “He ran like he was wanting to get it,” Manuel said, with the emphasis on “get.” Brown also made a deft shoestring catch. Brown blamed some of last year’s defensive woes on a knee he hurt while sliding for a ball in the minors. “It probably would have done some good just to sit out a little bit longer, but I wanted to play and wanted to be out there,” Brown said. “I don’t really think Charlie and those guys knew how badly I was hurting.” Brown’s spring has him head and shoulders above anybody else vying for a starting spot in the Phillies’ 2013 outfield. Darin Ruf’s struggles haven’t hurt, either. After Phillies general manager Ruben Amaro Jr. dumped Shane Victorino and Hunter Pence at the trade deadline last season, Brown was called up, and the second half of the season was largely considered an audition.
