Starkville, MS (SportsNetwork.com) - Dak Prescott solidified himself as a true Heisman Trophy candidate and his 12th-ranked Mississippi State Bulldogs emerged as a contender in the powerful SEC on Saturday with a thorough 48-31 victory over No. 6 Texas A&M at Davis Wade Stadium.

Prescott completed 19-of-25 passes for 259 yards with two touchdowns and ran for 77 yards with three scores, while Josh Robinson added 107 yards and two touchdowns on the ground for the Bulldogs (5-0, 2-0 SEC).

Mississippi State extended its winning streak to eight games dating back to last year. The Bulldogs have won their first five games for the second time in three seasons, although the 2012 team was 7-0 before losing five of its last six.

This year's Bulldog squad appears to be for real, winning consecutive games against top-10 teams for the first time in school history. They were idle last week after winning at then-No. 8 LSU for the first time since 1991. Another test against a ranked foe awaits next week when Auburn visits Scott Field.

Texas A&M quarterback Kenny Hill struggled for most of the first half, then turned it on in the second half and finished with 365 yards passing. He threw four touchdown passes, but was also intercepted three times.

The Aggies (5-1, 2-1), who had a six-game winning streak stopped, were trying for their first 6-0 start since the 1994 team opened with seven victories en route to a 10-0-1 season.
