Also among the home highlights: two visits each from the New York Yankees (April 20-22, July 5-7) and Boston Red Sox (July 19-21, Sept. 10-12), the annual series against the cross-bay rival San Francisco Giants (May 21-23), and a six-game stretch of Interleague Play against the National League Central's Cincinnati Reds (June 21-23) and Pittsburgh Pirates (June 24-27).
The road portion of the schedule starts after the conclusion of a four-game set against the Mariners to open the season (April 5-8), taking Oakland to Anaheim for a three-game weekend series against the Angels (April 9-11) before a trip up to Seattle for three games (April 12-14).
After that comes a 10-game homestand featuring four against the Baltimore Orioles, the Yankees' first visit and a three-game set against the Cleveland Indians.
The road-trip highlight for Oakland: an Interleague trip that starts just across the Bay Bridge for three games at the Giants' AT&T Park (June 11-13), continues on to Wrigley Field for a three-game series against the Chicago Cubs (June 15-17), followed by three games with the Cardinals at Busch Stadium (June 18-20).
The A's don't get their first look at the Texas Rangers, the surprise team of the American League West in 2009, until Texas comes to Oakland-Alameda County Coliseum on May 3-5.
The last homestand of the year also features the Rangers (Sept. 23-26), setting up a season-ending road trip to Anaheim (Sept. 27-29) and, fittingly, Seattle (Sept. 30-Oct. 3).
