Rickie Fowler and Henrik Stenson will lead the field competing at the 2018 Houston Open from 26 March to 1 April at the Golf Club of Houston.
Fowler is making his fifth consecutive start at the Houston Open.
Fowler and Stenson add to the top 25 world ranked players in the Houston Open field that includes Phil Mickelson and Rafael Cabrera Bello.
In 2017, Fowler opened the tournament with an eight-under 64 for a one-stroke lead on day one, staying in contention with Sung Kang the first three days of the Houston Open. Fowler closed out the Houston Open with a T3 and 27 birdies for the week, which marked his most birdies in a single event.
Major championship winner Stenson is making his seventh appearance at the Houston Open. It was in 2016 that Stenson finished runner-up at the Houston Open, one stroke behind winner Jim Herman, which was his third top-three finish in Houston.
Masters-bound Shubhankar Sharma accepted a sponsor exemption and is among the latest international commitments.
Sharma joins a growing international field of 37 players from 19 countries.
The 21-year-old from India made headlines with his first PGA Tour start in the 2018 World Golf Championships-Mexico Championship with a two-shot lead going into the final round, paired with Phil Mickelson in the final group, and finishing T9. Sharma is a two-time victor on the European Tour, recently winning the 2018 Joburg Open and 2018 Maybank Championship, which moved him into the world top 100.
Sharma is one of four international players committed to the Houston Open going to the Masters the following week.
He joins Cabrera Bello (Spain), Jhonattan Vegas (Venezuela) and Yuta Ikeda (Japan). In addition to defending champion Russell Henley, 2014 Houston Open champion Matt Jones of Australia, Englishman Lee Westwood and major championship winner Padraig Harrington of Ireland are in the field.
The Houston Open has historically attracted a stellar international field since its inception in 1946. Bobby Locke of South Africa was the first international Houston Open champion in 1947.
