For years, players have handed out signed swag - including hats, balls, shirts, etc. - to the thousands of fans lining the hole. In Saturday's round last year? Harrington kicked footballs into the crowd.
"Hadn't been planned at all," Harrington said. "I think I was asked on the Friday evening if I would do it, and, you know, I had no problem. I'm smart enough not to throw it."
Paddy's punts at 16 weren't the only positives he took away from TPC last year. He recorded his lowest finish of the year (T-9) and holds the event in high regard.
"I loved (playing here last year). Really did. ... This (tournament) is unique and there is nothing like it in golf."
Fans can expect more of the same - both with his golf and his antics at the 16th - this go-round.
"Footballs again," Harrington said. "We have actually the replica ball from the Super Bowl final. It's a pretty nice ball if you can catch it. ... Do everything the same (this year as last). Just try to putt a little better, chip a little better."
