Durazo, who bounced around Triple-A with three organizations last season, made the announcement on a Mexican radio station after hitting three home runs for Hermasillo of the Mexican Winter League, the Web site reported. The A's confirmed the development by text message, according to the report.
The A's obtained Durazo in a three-team trade in 2002, and in 2004 he set the club mark for batting average by a designated hitter at .324. He was let go after spending most of 2005 sidelined with an elbow injury. He's likely to get a look at first base in camp.
He hit a combined .286 in Triple-A last season for the top minor-league clubs of the Rangers, Yankees and Twins.
