Trevor Simsby of the United States moves up this week's World Amateur Golf Ranking thanks to victory in the Pac-12 Preview tournament at Pumpkin Ridge Golf Club in North Plains, Oregon.
The University of Washington player began the final round in fifth place, but closed with a 6-under-par 66 to take the title by a shot over Jon Rahm Rodriguez of Arizona State. Previous rounds of 69 and 70 gave Simsby a 54-hole total of 205, 11-under-par.
Simsby's victory made up for the absence of world number one Chris Williams, who could not play due to representing the United States in the World Amateur Team Championship in Turkey. Simsby's bogey free final round earned him his first collegiate title. He jumps 45 places on this week's ranking inside the top 100 to 86th. Rodriguez moves two spots to 34th.
England's Gregory Eason was a runaway winner of the Jack Nicklaus Invitational at Muirfield Village in Dublin, Ohio. The University of Central Florida player was the only player to break par over the 36 holes, returning consecutive 2-under-par 70s to finish on 140, 4-under-par. He defeated Purdue's Adam Schenk and AJ McInerney of UNLV by six shots.
Eason leaps 71 places this week to 123rd. Schenk moves to 457th from 754th, while McInerney is the world's 145th best player.
Gavin Hall overcame an 11-shot deficit to win the Ping Invitational over the Karsten Creek Course in Stillwater, Oklahoma. He posted a final round 70, 2-under-par, to earn a playoff against Cameron Champ. Hall won the title at the second playoff hole when he holed a four-foot par putt. It is the second AJGA win of Hall's career.
Hall jumps 904 places this week to become the world's 1423 ranked player. Champ improves 270 spots to 751st.
Isabelle Lendl appears to have made the right choice by not following father Ivan into tennis. The University of Florida player showed she has her father's winning mentality with victory in the Ruth's Chris Tar Heel tournament in Chapel Hill, North Carolina.
Lendl returned a closing 3-under-par 69 to take the title by three shots over England's Hayley Davis, a student at Baylor University. Previous rounds of 70 and 71 gave Lendl a 54-hole total of 210, 6-under-par.
The win is Lendl's second in successive tournaments, following victory in the Dale McNamara Invitational last month. Lendl is in her final year of college golf, and has three wins.
The victory moves Lendl 95 places on this week's World Amateur Golf Ranking. She moves to world number 312. Davis improves her status 25 spots to 91st.
Swaziland's Nobile Lamina continued her impressive run in amateur golf by winning the Ackerman Championship in South Africa. Dlamini took the title by four shots over South Africa's Kim Williams. Rounds of 74, 71 and 77 in testing conditions at Clovelly Golf Club in Cape Town gave Dlamini a 54-hole total of 222, 6-over-par.
Dlamini moves two spots on this week's ranking to fourth. Williams is the world's number 21 player.
South Africa's Paula Reto won the Mercedes-Benz Intercollegiate in Knoxville, Tennessee. The Purdue University player pipped Laura Wearn of Furman University by a shot after finishing on a 5-under-par total of 211. Reto moves three places this week to 16th, while Wearn moves to 178th, an improvement of 13 spots.
