Golic outraged over Thompson penalty call (2:07)

The golf world was atwitter over the four-stroke penalty assessed to Lexi Thompson as she was comfortably in the lead at the LPGA's first major, the ANA Inspiration in Rancho Mirage, California.

Thompson, who won the event in 2014, was cruising along with a two-shot lead and six holes to play when she was informed of the penalty by an LPGA official. A television viewer alerted officials that, on Saturday, Thompson had marked her ball and then put it back in an improper place before a 1-foot putt on the 17th green in the third round.

The LPGA didn't decide on a penalty until Sunday. Thompson was penalized two strokes for an incorrect ball placement and two strokes for an incorrect scorecard.

Golfers from Tiger Woods to Brittany Lincicome and even tennis hall-of-famer Chris Evert took to Twitter with their reactions.
