Colorado @ Oakland preview

Last Meeting ( Jun 30, 2015 ) Colorado 2, Oakland 1

The Colorado Rockies try for their first series victory on the road since May when they visit the Oakland Athletics on Wednesday in the rubber match of their three-game series involving last-place teams. Colorado snapped a 14-game road losing streak in American League ballparks and won for the first time in eight interleague games this season with a 2-1 victory Tuesday while avoiding Oakland ace Sonny Gray, who was a late scratch because of flu-like symptoms.

The Rockies (34-43), who have lost three straight road series since sweeping three games from Philadelphia from May 29-31, are 17-21 on the road after finishing 21-60 away from home last season. Colorado players own the two longest hitting streaks in the majors as reigning National League Player of the Week Nolan Arenado has hit in 17 straight and Troy Tulowitzki 's run sits at 14 after also extending his career high by reaching base in 29 consecutive contests. The Athletics (35-44) are a major league-worst 6-20 in one-run games and 10-31 in contests decided by two runs or fewer. Oakland's Jesse Hahn has done his best work in day games this season and opposes Chad Bettis, who has won his past two starts.
