DiMarco undergoes surgery on left shoulder

It's been almost two years since the United States team's Presidents Cup hopes rested on the shoulders of Chris DiMarco. On Wednesday, one of those shoulders needed some repairing.

DiMarco underwent arthroscopic surgery on his left shoulder in Orlando, part of a non-invasive procedure to clean up a bone spur around the acromioclavicular joint. His recovery period is expected to be about four to six weeks.

"I am glad I was able to take time off to have this surgery so that when I resume playing I can do so pain free," DiMarco said via a statement released by IMG Golf. "I can't wait to get back out and swing without pain."

In 17 events this year, DiMarco has finished in the top-25 six times and earned more than $950,000.
