Whoops, cheers and of course, alligators all took part in watching Justin Thomas swing into action on Friday at the RBC Heritage in Hilton Head.

Justin Thomas shot a 2-under 69 for a two-shot lead Friday at the RBC Heritage, his first 36-hole lead in more than four years.

At 10 under, Thomas commands a three-stroke lead over world No. 1 Scottie Scheffler and Arnold Palmer Invitational winner Russell Henley. Battling a bad back, former U.S. Open champion Wyndham Clark impressed in the early afternoon hours with a 65 of his own to stand four adrift.
