It was just last weekend that the Oakland Athletics and Los Angeles Angels got together to battle for first place in the American League West. After falling just short of getting the top spot back at home last weekend, the Athletics will try again on the road when they visit the Angels for the start of a four-game series on Thursday. Oakland enters the series one game back in the division, just as it was after taking two of three last weekend.The Angels managed to hang onto their slim advantage by taking two of three from the Miami Marlins, including a 6-1 triumph on Wednesday that included Mike Trout's 30th home run. The Athletics turned the same trick in a three-game series at Houston and have won four of their last six. The Los Angeles bullpen had a tough time in Oakland, squandering a lead in Friday's 5-3 loss before letting the go-ahead run score on Joe Smith's wild pitch in the eighth inning on Saturday.TV: 10:05 p.m. ET, MLB Network, CSN California (Oakland), FSN West (Los Angeles)PITCHING MATCHUP: Athletics RH Sonny Gray (13-7, 3.00 ERA) vs. Angels LH C.J.
