A's give Anderson $12.5 million, 4-year deal

Left-hander Brett Anderson and the Oakland Athletics have agreed to a $12.5 million, four-year contract that could be worth $31 million over six seasons.

Anderson receives a $1 million signing bonus, payable in equal installments on Aug. 5, Nov. 1, March 1 and Nov. 1, 2011. He gets $500,000 this year, $1 million next year, $3 million in 2012 and $5.5 million in 2013, and Oakland has options for $8 million in 2014 and $12 million in 2015.

If either option is declined, he would get a $1.5 million buyout. Oakland must decide within 10 days of the end of the season whether to exercise the following year's option.

Anderson's deal replaces a one-year contract reached in February that called for salaries of $410,000 in the majors and $240,000 in the minors.

A 2008 U.S. Olympian, Anderson went 11-11 with a 4.06 ERA in his rookie season for the A's last year. He threw 175 1-3 innings and struck out 150 batters to just 45 walks. He is 1-0 in two starts this season.
