It's a fair question to ask both Choo and shortstop Elvis Andrus, who was also working out at the high school as part of a minicamp for younger players.
Choo was on the disabled list four times last year because of a strained right calf muscle, strained left hamstring, lower back inflammation and a broken left forearm. He played in just 48 games.
Andrus never went on the DL and played in 147 games. But it was revealed after the season Andrus had been dealing with a sports hernia since mid-May, and he underwent surgery in October.
