After being shutout by the New York Yankees on consecutive days, Billy Beane is looking to his struggling offense a boost. Should the A's look to the minors for help, Matt Watson and Shawn Garrett are hitting for average at Sacramento, while Jack Cust and Dan Johnson have some power and 19 RBIs each. "We need to get the offense going,'' assistant GM David Forst said flatly. The A's 108 runs are the fewest in the league.
