Caddies have some serious complaints

A rift between caddies for some of golf's greatest players and US PGA Tour officials, which has resulted in a lawsuit, appears to be growing.

Duane Bock, a caddie for US PGA player Kevin Kisner, says a tour official scolded him for wearing salmon-red shorts last weekend at Bay Hill during the Arnold Palmer Invitational.

Bock tweeted on Monday about his Facebook posting on Saturday following the third round of the tournament, with a photo of him in knee-length shorts and a message.
