(CNN) -- Tiger Woods was penalized two strokes Saturday after a rules committee deemed he violated one of golf's ball-drop rules during Friday's play, an official with the Masters Tournament said.
Woods, a four-time tournament champion, hit a shot on the 15th hole that ricocheted off the flagstick into a pond. Woods took a drop then bogeyed the hole.
"After being prompted by a television viewer, the Rules Committee reviewed a video of the shot while he was playing the 18th hole," Fred Ridley, the Augusta National Golf Club's competition committee chairman, said in a written statement.
At that time the committee determined Woods hadn't broken any rules, but later met with Woods after he described where he stood to drop the ball.
Woods is now 1-under par, five strokes behind leader Jason Day.
The committee didn't disqualify Woods for signing an improper scorecard because it made its "initial determination prior to the finish of the player's round."
