SINGAPORE - Breaststroke specialist Lionel Khoo rewrote his 200m national mark on Thursday (March 1), after he clocked 2min 15.24sec in the B final at the TYR Pro Swim Series in Atlanta, Georgia.
He finished third in the race, behind Chinese swimmer Liu Yunsong (2:13.33) and Argentinian Gabriel Osvaldo (2:15.19).
Khoo had clocked 2:17.95 in the heats earlier in the day.
The A Final was won by Andrew Wilson (2:08.95), who touched the wall ahead of Will Licon (2:09.47) and Josh Prenot (2:10.43). All three are Americans.
Khoo, 22, also held the previous national mark of 2:15.27, set in March last year at the China Life Insurance Singapore National Age-Group Championships.
Khoo holds the 100m and 200m national breaststroke records for short and long course, and the 50m breaststroke national record for short course.
In January, he left Singapore to study and train at the University of South Carolina, joining senior national swimmers such as Joseph Schooling (University of Texas at Austin), Quah Zheng Wen (UC Berkeley) and Quah Jing Wen (Texas A&M) in the United States.
Khoo is pencilled in to race in Saturday's 100m breaststroke event at the meet in Georgia, which is the second stop of six in the series.
