After a forgettable stint in the Dominican winter league—he went 2 for 29 for Escogido before heading home early because he "just played bad"—Brown spent the rest of his off-season bulking up (adding 10 pounds of muscle) and tweaking his swing (his new stroke is more compact). The prize prospect, a five-tool talent who hit .210 in 35 games with Philly last season, hopes the winter work helps him lock down the rightfield job vacated by free agent Jayson Werth. The Phillies, though, may start the season with Brown, 23, in a platoon. "He played in the minors for a short period of time," says manager Charlie Manuel. "He's still definitely learning how to play baseball."
