What It Means:

The center fielder hasn't played since last Wednesday due to tightness in his right hamstring. Sam Fuld is in center field Tuesday.

Burns, a 26-year-old rookie, has fared well in his first season in Oakland, although just 26 of his 138 hits have gone for extra bases. He's slashing .297/.336/.388 with 26 steals. We project him to post a .683 OPS with four more stolen bases the rest of the way, assuming the leg ailment doesn't force him to miss significantly more time.
