The Northern Irishman followed up his opening round of 69 to hole seven birdies and a bogey on his way to a 66, leaving him on nine-under-par overall.
The American trio of Bo van Pelt, Jim Furyk and Keegan Bradley ended the day on six-under, while a 69 gave Tiger Woods a score of five-under.
Overnight leader Nick Watney will go into Saturday on four-under with fellow countryman Rickie Fowler.
However, it was a bad day for McDowell's Ryder Cup teammate Ian Poulter, who is now 10 shots off the lead thanks to a 72.
