In a dominating performance, Christian Walker's two home runs and Zac Gallen's strong five innings propelled the Arizona Diamondbacks to a 6-0 victory over the Texas Rangers.
The win puts Arizona just a half-game behind San Diego for the top NL wild-card spot, while Texas faces an uphill battle for the AL wild card.
Both teams are looking to secure their playoff positions as the regular season nears its end.
