The A's will make the announcement on Friday, the Chronicle reported.
Conversations between Garciaparra, who had been contemplating retirement, and the A's have been percolating for a couple of weeks.
Garciaparra, 35, batted .264 in 55 games for the Dodgers last season, as he battled injuries. Oakland's interest in him is presumably to help them balance their lineup: The right-handed hitting Garciaparra hammered lefties last season, going 19-for-56, with four homers and a 1.067 OPS.
Seems to me like Billy Beane realises it isn't going to take much to win this division this year, so he's picking up everyone left off the scrap heap.
