American golfer Grayson Murray may hire a new caddy in stunning Playboy model Lindsey Pelas. But in order for the blonde to do that, the 23-year-old Murray must win the Shell Houston Open on March 30. Murray, who requested Pelas for the job on Twitter, revealed it would give him extra motivation if Pelas could be his caddy. “Hey @LindseyPelas if I win next week in Houston will you be my caddy in the par 3 tournament at The Masters?” Pelas didn’t hesitate in her response. “Obviously,” she replied.
