FORT WORTH, Texas -- Pat Perez withdrew during Thursday's first round of the Crowne Plaza Invitational at Colonial with a shoulder strain.
Perez, who started his round off the 10th tee, had played seven holes and was 2 over when he withdrew after making a par at the par-3 16th.
"He said he hurt his neck last week at the (HP Byron Nelson Championship) and he was in pain," said playing partner Brendon de Jonge. "You could see from the start. He tried to play through, but you could see he was hurting."
Perez was making his ninth career start at Colonial. He also had to withdraw in this event 10 years ago after the first round.
