ESPN.com’s Buster Olney is reporting that A’s closer Andrew Bailey and outfielder Ryan Sweeney have been traded to the Red Sox for right fielder Josh Reddick and two minor leaguers, third baseman Miles Head and right-hander Raul Alcantara.

Bailey, 27, is eligible for arbitration for the first time after making only $465,000 this year, would be under the Red Sox control for the next three seasons.

The 2009 AL Rookie of the Year was raised in New Jersey and posted a 2.18 ERA, 25 saves and a 1.17 WHIP in 45 career appearances last season.

Sweeney, 26, is a left-handed hitter, like Reddick, but has more experience. He batted .265 with one homer, 25 RBI and a .687 OPS last season and is a .283 hitter over parts of six seasons with the White Sox and A’s.

Reddick, 24, batted .280 with seven homers and 28 RBIs in 87 games for Boston in 2011 and can play any outfield spot.

Bailey becomes the fourth pitcher traded by the A’s who already dealt starters Gio Gonzalez and Trevor Cahill, and reliever Craig Breslow.
