Oakland split a 4 game series with the Tigers over the weekend, while the Angels lost 2 of 3 in Texas including last night's 13-6 loss on Sunday Night Baseball. The A's are now 18-17 on the season and 9-7 on the road, while the Angels are just 15-20 on the year and 9-8 at home. Tonight we have the same pitching match up we saw on April 17th in a 5-3 Oakland win. Tyson Ross is just 1-3 on the season with a 7.71 ERA, 1.83 WHIP, and .336 opponents batting average, but those numbers are inflated due to two poor outings @TB and @Balt. Ross started the season off with two quality outings and allowed just 3 earned runs against in 5.2 innings of work against the Blue Jays in his last time out. In his start vs the Angels he went 6 innings allowing 7 hits and 2 earned runs. The Angels counter with Dan Haren who is 1-3 on the season with a 4.19 ERA, 1.33 WHIP, and .287 opponents batting average. In his last star Haren went just 3.2 innings vs the Twins allowing 8 hits and 5 earned runs. He has had three very quality starts this season, but hasn't been consistent throughout the first month and a half of the season. The Angels are just 1-6 in Haren's 7 starts this season. Note that the A's are 2-3 in Ross's starts. Also note that the Angels are 4-10 in their last 14 vs a team with a winning record and 1-5 in their last 6 vs AL West opponents. Los Angeles is also just 1-7 in Haren's last 8 starts dating back to last season, and 1-6 in his last 7 starts as a home favorite of -151 to -200. The A's are 4-1 in their last 5 games as a road underdog and already took 3 of 4 in Los Angeles this season. Take note that the Angels are 0-4 in Haren's last 4 starts vs the Athletics. With the Angels coming off a 6 game road trip including last night's emotional lost in the Sunday Night'er it is going to be a good spot for the A's who are fresh off a 6 game home stand. The A's have already won this same pitching match up earlier in the season, and they are in a good spot to pull it off again.
