David DeJesus' brief, disappointing stay in Oakland is officially over. The free-agent outfielder has joined the Chicago Cubs, agreeing to a two-year contract with a club option for 2014, the Cubs announced Wednesday.

DeJesus, who'll turn 32 later this month, had the worst offensive year of his nine-year career with the A's in 2011. DeJesus had career lows with a .240 batting average and a .698 OPS (on-base plus slugging) in his only season with Oakland, which acquired him in a trade with Kansas City for pitcher Vin Mazzaro and a minor-leaguer last offseason.

The A's, who offered the Type B free agent DeJesus arbitration last week, will receive a supplemental pick in 2012.

Oakland's regular 2011 outfield of DeJesus, Josh Willingham and Coco Crisp were all free agents after the season. While the A's reportedly have some interest in retaining Crisp, Willingham, a Type A free agent who will net Oakland two draft choices, is expected to sign elsewhere.

Oakland currently has just four outfielders on its 40-man roster, with Ryan Sweeney the only one who has seen any significant time in the majors. Other A's outfielders on their roster include Michael Taylor, Jai Miller and Jermaine Mitchell.

Chicago will pay DeJesus at least $10 million to be their regular right fielder. DeJesus reportedly will make $4.25 million in each of his first two years, with the Cubs option for 2014 worth $6.5 million with a $1.5 million buyout.

DeJesus becomes the first player acquired by new Cubs president Theo Epstein, the former Boston Red Sox general manager who has long coveted DeJesus.

In 1,007 major league games, nearly all with Kansas City, DeJesus has posted a batting average of .284 with 207 doubles, 50 triples, 71 home runs, 436 RBIs and a .356 on-base percentage.
