Brian Wacker of PGATour.com reports that the two actually did it on purpose.
"Jonas Blixt, who is also sponsored by Puma and is paired with Fowler, showed up at Liberty National in the same outfit -- one he actually borrowed from Fowler.
The two had been talking about going all-orange if they ever played together on a Sunday. When Blixt found out they would be, he tried to get Puma to ship him the same outfit, only it wouldn't arrive by their 1 p.m. ET tee time.
"You can't plan for being paired in the final round," said Fowler, who had an extra pair of orange pants and an orange shirt that he left in Blixt's locker."
I'm not totally sure why one person would want to dress like this, much less two, much less two guys playing together but hey, I guess it's good for Puma.
And better for those of us watching on TV who won't see much of their rounds as both golfers are well back of the leaders.
