It marks the third consecutive first game win for Alabama in WCWS appearances (2011 and 2012 previously). The Crimson Tide got the win over defending national champion Oklahoma in the day one feature match of the past two WCWS winners.
Coach Patrick Murphy's Crimson Tide improved to 51-11, while the Sooners fell to 50-12.
The important first day win keeps Bama in the winner's bracket. Three Southeastern Conference teams were among the four winners on day one with Florida and Kentucky also winning. Also winning was Oregon.
Alabama returns to action Friday at 8:30 p.m. CDT against Kentucky. It will mark the first time the two teams have faced each other this season. The game will be televised on ESPN2.
Senior All-American Jaclyn Traina picked up the win for Alabama in the pitching circle, pushing her record to 24-3 on the season, while Kelsey Stevens took the loss for Oklahoma, falling to 37-9.
After trading runs in the first two innings, Oklahoma went up 2-1 in the top of the fourth inning. From there, Alabama used homeruns in the bottom of the fourth and fifth innings to grab a 6-2 lead. It was the Tide's fourth multi-homer game of the 2014 NCAA tourney.
In the bottom of the fourth freshman Peyton Grantham homered to left center field, driving in senior Kaila Hunt and senior Molly Fichtner. In the next inning junior Jadyn Spencer sent one over the left-field wall, bringing in sophomore Kallie Case.
Grantham now has three hits since the start of the NCAA tourney, two of which have been home runs.
