Shortstop Bobby Crosby took some grounders in Fenway Park Saturday, taking another step toward returning to the A's lineup. Crosby later took part in agility drills with strength and conditioning coach Clarence Cockrell. "He did very well," trainer Larry Davis told the Contra Costa Times. "It was a limited workout, but there was no soreness and pain." It appears Crosby could return to the lineup possibly Tuesday or Wednesday.
