The introduction of the Houston Astros to the American League West and interleague home games against three of baseball’s most storied franchises — the Chicago Cubs, St. Louis Cardinals and Cincinnati Reds — highlight the 2013 A’s schedule, which was announced Wednesday.

The A’s and manager Bob Melvin will open their season for the fourth straight year against the Seattle Mariners at the Coliseum on April 1. Oakland wastes no time in getting to know the Astros, as it will hit the road for a three-game series starting April 5.

Due to the Astros making their AL West debut next season, the A’s will play only four games against the cross-Bay rival Giants — compared to six previously — in interleague play next season, visiting AT&T Park on May 27-28 and then hosting the Giants at the Coliseum on May 29-30.

Next season’s slate also features the Cubs’ first appearance in Oakland, as they visit the A’s for a three-game series July 2-4. Other interleague home games on tap include the 2011 World Series champion Cardinals for a three-game weekend series June 28-30 and the current NL Central Division-leading Reds in a two-game set June 25-26.
