Los Angeles @ Oakland preview

Last Meeting ( Jul 15, 2011 ) LA Angels 3, Oakland 5

THE STORY: Saturday offers a rarity in Major League Baseball - a scheduled doubleheader. How rare? Well, the last time it was done was eight summers ago. On Saturday, the Oakland Athletics will host the American League West-rival Los Angeles Angels in the first regularly scheduled doubleheader since 2003. Both teams had to agree to the twinbill prior to the league releasing the schedule. Oakland snapped a four-game losing skid with a 5-3 triumph in the opener of a four-game set on Friday. For its part, Los Angeles saw its four-game winning streak come to an end and fell for just the fourth time in 18 games.

PITCHING MATCHUP: Game 1: Angels RH Jered Weaver (11-4, 1.86 ERA) vs. Athletics RH Trevor Cahill (8-7, 3.12 ERA).

Weaver has been downright dominant in building a five-game winning streak. The 28-year-old All-Star hurler has yielded just four runs in his last five starts - collecting two complete games in the process. Although Weaver is just 4-6 in his career against the Athletics, he has pitched well against them this season. Weaver tossed a complete-game shutout on April 25 and recorded a no-decision after yielding just one run in seven innings on May 23.

Cahill has dropped two in a row and seven of his last nine decisions. The 23-year-old hurler yielded two runs on five hits in 7 2/3 innings in his last start - which resulted in a 2-0 loss to the Texas Rangers on Sunday. Cahill is 4-2 in his career against the Angels.

ABOUT THE ANGELS (50-43): Los Angeles placed outfielder Peter Bourjos on the 15-day disabled list with a hamstring injury. With Bourjos sidelined, prospect Mike Trout collected his first career RBI with a run-scoring single in the sixth inning on Friday. Erick Aybar had two hits - including an RBI single - to extend his hitting streak to seven games. Aybar is 6-for-20 in his career against Cahill and 0-for-3 versus Harden. After going 0-for-4 on Friday, Torii Hunter is just 3-for-23 in his last eight games at Oakland. Hunter is just 4-for-17 against Cahill and 2-for-11 versus Harden.

ABOUT THE ATHLETICS (40-53): With little opportunity for playing time, Oakland optioned left fielder Chris Carter to the minors. Josh Willingham, who was shuffled to third in the lineup, belted a 446-foot, two-run homer on Friday. He is now 9-for-20 with a pair of homers since returning from the disabled list. Hideki Matsui, who is now batting cleanup, snapped an 0-for-18 skid with an RBI single in the eighth inning on Friday. He is still searching for his 500th professional home run - combining his totals in North America and Japan. Matsui, who hasn't homered since June 16, is 4-for-16 in his career versus Weaver and 2-for-12 with two homers against Santana. Reliever Joey Devine left Friday's game with an injury to his right side. Given Saturday's doubleheader, the team is more than likely to make a move to bolster its relief corps.

FINAL PITCH: Although Oakland has struggled against its division rivals, it has won six of its last eight against Los Angeles. All told, the Athletics are 14-16 versus the American League West this season.
