The Arizona Diamondbacks, fresh off a three-game sweep of the Los Angeles Dodgers, are now in prime position to host the National League Wild Card game, and they are $1.90 favourites to continue that form over their NL West division rivals, the Colorado Rockies ($1.92), in the first of three weekend games at Coors Field.
Taijuan Walker will start on the mound for the Diamondbacks having won his last start against Madison Bumgarner and the San Francisco Giants at home on August 27. However, that was his first win as a starting pitcher since June 22, which came on the road against the Colorado Rockies.
