The A's signed Hideki Matsui and traded for Josh Willingham and David DeJesus in the hopes of bolstering production from the outfield and at DH. The moves could push Ryan Sweeney into a fourth-outfielder role, which would be a mistake. Since becoming a regular in 2008, Sweeney has been one of the 20 best defensive players in baseball, saving 20 runs with his glove. He's an adequate hitter, batting .286/.341/.386 in his career, a line that is acceptable given his great defense. Matsui has played just 317 innings in the outfield over the past three seasons, while Willingham's below-average glove costs his team a few runs—the gap between him and Sweeney is about 2½ wins per year. It's not clear that playing Willingham (.265/.367/.475 in his career) over Sweeney will produce enough runs offensively to make up for the loss defensively, especially given the extensive foul ground at Oakland--Alameda County Coliseum. A DH platoon of Matsui and Willingham, with Sweeney and DeJesus flanking centerfielder Coco Crisp in the outfield, is the team's best alignment when everyone is healthy.
