Bobby Crosby hopes his second comeback of the season is as successful as his first. The Oakland Athletics activated the reigning AL rookie of the year from the 15-day disabled list Monday and rewrote the lineup with him at shortstop and batting seventh for the opener of a three-game series against the Minnesota Twins. Crosby, recovering from a fractured left ankle that forced him into a second stint on the DL this year, fielded groundballs, ran the bases and took batting practice in the cage before the A's decided he was ready to go -- or as ready as he's going to be for the stretch run. "My feeling is why not get him back in there, kind of like last time," manager Ken Macha said. "The sooner we get him back on the field and get him some at-bats, the sooner he'll get going."
