2011: Struggled in an injury-plagued season on the PGA TOUR with only five made cuts in 19 starts.

Withdrew from the Greenbrier Classic in July after the first round and did not play again until October in Las Vegas.

Best finish was a 53rd-place showing at the Sony Open in Hawaii. 2010: Earned his third win of the year with a two-stroke victory over Josh Teater at the inaugural Christmas In October Classic. Shared the 36-hole lead and held a three-shot advantage heading into the final round at the Nicklaus GC at LionsGate. Was in a head-to-head battle with Teater during the final round when Teater suffered a double bogey at No. 15 to give Sim a two-shot edge. Played bogey-free on the weekend to take the win and become the ninth player in Tour history to earn a "battlefield promotion" to the PGA TOUR. First-place check of $112,500 pushed his season total to $527,079 and broke the Tour's single-season money record of $495,009 held by Troy Matteson in 2005. Money-record total was earned in just 12 starts, giving him an average of $43,923 in each start.

Earned his second career win, at the inaugural Stonebrae Classic, thanks to a final-round, 7-under 64. He held a one-stroke lead over Matt Every after 54 holes at TPC San Francisco Bay. Closed the front nine Sunday with four consecutive birdies to increase his lead to four shots at the turn. Added a birdie and an eagle on the back nine and went on to win by six shots over Cameron Percy and John Kimbell. First-place check of $108,000 vaulted him to No. 1 on the money list.

Picked up his second win of the year with a playoff victory over Fabian Gomez at the BMW Charity Pro-Am. Parred the first extra hole to beat Gomez and even his career playoff record to 2-2. Fired a career-best 62 in the third round and grabbed a three-stroke lead heading into the final round. His 2-under 69 was enough to force a playoff with Gomez. Also teamed with singer Javier Colon to win the celebrity/amateur portion of the tournament. The team finished at 47-under par and won by three strokes.

Finished solo third at the Moonah Classic, where he shared the 36-hole lead with Miguel Carballo.

Followed with a T4 at the HSBC New Zealand PGA Championship the next week.

Earned his fourth top-10 in six starts with a runner-up finish at the Athens Regional Foundation Classic. Tied the Jennings Mill CC record with a 9-under 63 in the fourth round to finish at 14-under par, completing his round more than an hour in front of the final pairings. Forced into a playoff when Patrick Sheehan birdied the last hole of regulation. Sheehan then birdied the first hole of the extra session from 22 feet to earn the win.

Finished T10 at the Melwood Prince George's County Open. After playing 36 holes Sunday at Melwood due to a weather delay earlier in the week, he successfully qualified for the U.S. Open the following day at a 36-hole sectional in nearby Rockville, MD. Went on to make the cut at the U.S. Open, where he was paired with Tiger Woods in final round on his way to a T18 finish.
