Game of the day: Oakland at Los Angeles Angels, 10:05 p.m. The American League West continues to tighten, and all four teams’ mediocrity is creating what could turn out to be a compelling division race. Oakland (22-25) has lost five games in a row, but the A’s still find themselves only two games out of first place and 1.5 games behind Los Angeles (24-24) heading into this four-game series. Left-hander Josh Outman will start for Oakland in what will be his first major league appearance since he had Tommy John surgery in July 2009. Right-hander Jered Weaver (6-4) will start for Los Angeles, looking for his first win since April 25. Weaver has lost four straight starts after opening the year 6-0.

Other game to watch:

Boston at Cleveland, 7:05 p.m. The Red Sox (25-21) have won eight of their last nine games while the Indians (29-15) have the best record in the major leagues. Right-hander Clay Buchholz (4-3) will start for Boston, coming off seven scoreless innings in his last start Wednesday against Detroit. Buchholz took the no-decision in that game, but he won his previous three starts before that. Former Red Sox right-hander Justin Masterson (5-2) will start for Cleveland, looking for his first win since April 26 after he started the season 5-0. Masterson allowed just one run in eight innings during his last start Wednesday against the White Sox, but he took the loss in Chicago’s 1-0 win.
