McGirt, having made his ninth straight cut dating back to last year, finished with a pair of birdies for a final-round 3-under-par 69 that left him at 13-under-par 275 for the tournament, good for a tie for 30th and a $31,857 check.
McGirt started strong Sunday, birdieing Nos. 2 and 3 on the PGA West course, and then holed out from off the green on the par 5 No. 6 for an eagle to go 4 under for the day. But his drive on the next hole found the water, and he made four bogeys and a single birdie during a seven-hole stretch before birdieing the last two holes.
For the week, McGirt finished second in putts per round, but just 67th in greens hit in regulation, a flip from the Sony Open when his ball striking was strong, but he struggled on the greens.
McGirt has now earned $100,883 for the season, good for 33rd on the PGA Tour. His scoring average of 69.46 is 24th best on the tour.
McGirt will play in the Farmers Insurance Open that begins Thursday and the AT&T Pebble Beach National Pro-Am that begins Feb. 9. It was unclear when this was written whether he was eligible to compete in the Waste Management Phoenix Open that begins Feb. 2
