Victorino (back) arrived at training camp Wednesday, one week before he was scheduled to report, ESPN Boston reports.Victorino is coming off back surgery and understands the situation he's facing. There's a log-jam in Boston's outfield and he'll need to win the starting right field job. His main competition at this point is Mookie Betts, a converted infielder who started just eight games in right field last season, but is the team's best choice to lead off. Victorino says he's been working out, taking live batting practice and running without any setbacks.
