The first New England score of the quarter broke a 7-7 tie less than a minute into the period when Shane Vereen ran it in from one yard out to quickly put the Patriots up 14-7.
The Patriots then extended their lead with 6:31 remaining when Tom Brady connected with Rob Gronkowski on a seven-yard touchdown pass. This made it 21-7 and called for a nifty celebration from the New England tight end.
Finally, with time winding down in the half, Stevan Ridley went one yard to cap the scoring and put the Patriots up 28-7 at the break.
With 30 minutes of football still left to be played, it will take a sizable comeback from St. Louis to get back into the game. Quarterback Sam Bradford was 14-for-16 passing in the first half for 146 yards, one touchdown and zero interceptions.
The Patriots are in control for now, however, thanks to Brady's two touchdown passes and five total receptions from Gronkowski for 106 yards. On the ground, the combined efforts of Vereen and Ridley lead the way for the Patriots. New England is also 5-for-6 on third downs.
