Near the middle of Domonic Brown’s spectacular spring training, he commented one day about how his fastball approach had changed. He had lost some focus on hitting fastballs as he struggled to live up to his blue-chip prospect status. “Now I’m hunting the fastball,” Brown said Feb. 27. After his nine-homer spring training, Brown struggled to begin the season. He’s found his stride of late, even as pitchers start to learn Brown’s tendency to mash fastballs early in the count. “That’s just playing the chess match,” Brown said Thursday. “Baseball is a cat-and-mouse game. You just gotta keep making adjustments every day.” In his last six games, Brown hit .348 with two home runs, a triple and two doubles to go along with seven RBIs. The performance earned him National League Player of the Week honors. “It feels good, man,” Brown said Tuesday. With the award, Brown becomes the first Phillies position player to win the award since Raul Ibanez did it in July 2011. Brown attributes his power surge to a shortened swing, something he worked on this season. As he struggled through the minors, he could get away with a longer swing thanks to less-talented pitching. “Me being 6-5, longer arms, I gotta be short to the baseball,” Brown said. “Just going out, watching a lot of film and being around coaches, it’s a little bit of everything.”
