Phil Mickelson caused a minor commotion with his pants and his putter.
The Deutsche Bank Championship began with players on opposite ends of the world ranking — Luke Donald at No. 1, Troy Matteson at No. 207 — having their lowest opening round of the year.
Matteson, facing elimination from the FedEx Cup playoffs, overcame a bogey on the first hole for a 6-under 65 and the outright lead after the first round. Donald had a 66 and was among those one shot behind.
Through it all, Mickelson brought attention to himself for two items that looked out of place.
The day after he wore a Red Sox jersey while throwing out the first pitch before the Yankees' 4-2 win at Fenway, Mickelson wore pinstripes at TPC Boston.
"Lost a wager with a friend and had to wear these today," Mickelson said. "What can you say?"
Stranger still was the sight of Mickelson sticking the grip of a long putter into his gut.
Mickelson still missed his share of putts in a round of 70, but he sounded as though he was willing to stick with the belly putter — at least for the rest of the week.
