CASTLE ROCK — It might have been Gabe Landeskog’s first time participating in a pro-am golf tournament, but he didn’t miss a chance to show off his best Tiger Woods impersonation. Landeskog sunk putts to finish off the front and back nines Wednesday at Castle Pines Golf Club. Both times he pulled off a muted Woods-style fist pump to a smattering of cheers from the crowd. “My putter was hot today,” Landeskog said.
