The Texas Rangers haven't won a series since late June and have a chance to end that dubious fact when they host the Oakland Athletics on Sunday in the finale of a three-game set. Texas has lost 28 of its past 34 games after falling to the Athletics on Saturday and last won a series when it took two of three from the Minnesota Twins from June 27-29. Oakland bounced back from Friday's series-opening loss by pounding four homers in Saturday's 5-1 win.John Jaso hit a two-run homer in the sixth to get the Athletics' power display going and Yoenis Cespedes, Josh Donaldson and Josh Reddick added solo shots as Oakland improved the best record in the majors to 64-39. "Home runs are part of our game," manager Bob Melvin told reporters afterward, "so you just have to stay with it at times when you go into some droughts a few innings in a row and know that one swing can get you going." The struggling Rangers possess the worst record (41-63) in the big leagues and also own the worst home mark at 19-31.
