NORTON -- Bruins forward Shawn Thornton, one of the more avid golfers on the hockey club, spent Friday on the course at TPC Boston following Keegan Bradley and his playing partners Hunter Mahan and Matt Kuchar in the first round of the Deutsche Bank Championship.

He served as the PGA Tour's official tweeter for that group and posted his observations on Twitter for @PGATOUR.

Here's a sampling of his tweet updates:

1:04 p.m. -- Happy to be out here at TPC Boston inside the ropes with Keegan. Amazed how fast these guys walk. Where's the fire, boys? ^ST

1:25 p.m. -- It's also crazy to hear the sound off their clubs. It's so different than anyone I play with. It's like a shotgun. ^ST

1:52 p.m. -- Observation: PLAYERS Champion Matt Kuchar is much taller than you think he is. ^ST

2:14 p.m. -- There are a ton of @NHLBruins fans out here. I'm getting "Go B's" every 10 seconds! ^ST

3:22 p.m. -- Awesome birdie by Keegan at 9. Cool to see him battle back to +1 after some hiccups. ^ST

3:39 p.m. -- Keegan is on a roll now. He just made his third straight birdie to get back to even. A hat trick joke would be too cheesy. ^ST

4:06 p.m. -- Incredible birdie by Keegan [at No. 12]. Pushed his tee shot right and had a blind second over a hill. I easily could have made 9 from there. ^ST
