The first round of the 2026 CHAU-SHI Series – Mizuno Open, with a total purse of NT$3 million, was played today (June 3) at Bombax Golf Country Club in Tainan. Taiwan’s young talents Wang Hsi-an and Hsieh Ting-wei, along with Japan’s Yuya Tokumitsu, each carded 5-under-par 67s to share the first-round lead. Mizuno-sponsored player Hsieh Tung-hung posted a 4-under-par 68 to join Taiwan’s Lu Sun-yi, Shen Wei-cheng, Peng Hsiung, and Japan’s Keita Okada in a tie for fourth place. Chang Che-yu, Su Chin-hung, Ho Yu-cheng, Thailand’s Pattanan Bruminhent, and Japan’s Yuji Sekito all returned 3-under-par 69s to share ninth place. The second round will be played tomorrow (June 4), again with morning and afternoon waves and split-tee starts from the 1st and 10th tees. The first group in the morning wave will tee off at 6:30 a.m., while the first group in the afternoon wave will start at 11:20 a.m. Following the completion of the first two rounds, the top 50 players and ties will advance to the final two rounds. Players endured extreme heat today, with the temperature feeling as high as 37–38 degrees Celsius. Wang Hsi-an, who recently turned 28, combined strong iron play with excellent putting, making six birdies against one bogey. He birdied all four par-5 holes, the 5th, 9th, 13th, and 16th. The firm fairways, hardened by several rainless days, allowed the ball to roll significantly, including a 380-yard drive on the 13th hole. Supported by precise iron shots and accurate green-reading and pace control, Wang posted an impressive 67 and joined the leaders early in the day. Wang said that after turning professional five years ago, his game has steadily improved in recent seasons. He has now retained his Taiwan Tour card for three consecutive years. His proudest achievement came in May at the International Series Taiwan Glass Taifong Open on the Asian Tour, where he made his first Asian Tour cut and eventually finished tied for 42nd, earning the largest paycheck of his career. He described the result as the biggest breakthrough of his professional career, crediting a change in mentality. Working with his coach over the past three years, the first two focused on technical improvement, while this year has emphasized mental stability and overcoming the impatience that characterized his younger years. Hsieh Ting-wei, who won the opening event of the ThreeBond Challenge Tour at Bombax Golf Country Club in both 2025 and 2026, also posted a 67 to share the lead after recording one eagle, six birdies, and three bogeys with only 25 putts. Hsieh said his driving was solid today, but his short-iron play was below standard, particularly on approaches from 50 to 100 yards and some shots from 60 to 70 yards. Fortunately, his putting was excellent. He holed 10-foot birdie putts on both the 3rd and 8th holes, converted an 18-foot birdie putt on the 7th, drained a 27-foot eagle putt on the 9th, and added another birdie from 15 feet on the 16th hole. The 26-year-old Hsieh won the TPGA Rookie of the Year Award last season. This year he is focusing on both the Taiwan Tour and the Asian Development Tour (ADT). So far, he has finished tied for 18th at the CHAU-SHI Series Chang Wah Open, won the opening event of the ThreeBond Challenge Tour, and recorded tied 28th and tied 16th-place finishes in ADT events in Vietnam and Thailand, respectively. Following this tournament, he will travel to the Philippines in mid-June for his third ADT event of the season. Japan’s Yuya Tokumitsu, 26, who topped the 2026 Taiwan Tour Qualifying School in January, also carded a 67 after recording six birdies and one bogey while needing only 28 putts. Starting from the 10th hole in the morning wave, Tokumitsu birdied his opening hole and added birdies on the par-5 13th and 16th holes. After making the turn, he holed a 23-foot birdie putt on the par-3 2nd hole, one of the highlights of his round. He added further birdies on the par-5 5th and 9th holes. His only bogey came on the par-3 8th hole after a poor chip left him with a long six-meter putt. Overall, he credited both steady driving and iron play, along with a strong putting performance. Lu Sun-yi felt that his iron play was the weakest part of his game today, but excellent putting and chipping allowed him to post his first score in the 60s this season, a 68. He executed a 40-yard chip perfectly on the 1st hole and a 60-yard chip on the 7th, leaving short birdie putts. The highlight came on the 15th hole, where he chipped in directly. Mizuno-sponsored player Hsieh Tung-hung eagled both the 3rd and 9th holes but also made bogeys on the 4th and 6th. After the turn, he added three birdies and one bogey on the back nine to finish with matching 34s and a 68. He said the extreme heat made green-reading and distance control difficult, and he was very satisfied to post a score of 68. The tournament features 138 players from six countries and regions. In addition to the host nation, competitors come from Hong Kong, Japan, the Philippines, Thailand, and the United States. The field includes 125 professionals, comprising 90 Taiwanese professionals and 35 international players, with Japan contributing the largest overseas contingent of 25 players, followed by Thailand with seven. Thirteen Taiwanese amateurs are also competing for the championship trophy and the winner’s prize of NT$500,000. The runner-up will receive NT$250,000. This tournament is the third event of the 2026 CHAU-SHI Series and the fifth event on the Taiwan Tour schedule. It is also the only tournament to have been included every year since the CHAU-SHI Series was launched in 2021 under the title sponsorship of Wong Chau-shi, Honorary Chairman of Mercuries Group. The event is presented by Mizuno Taiwan, organized by The PGA of Taiwan (TPGA), and supported by Bombax Golf Country Club as principal sponsor and co-organizer. This year also marks the 120th anniversary of Mizuno, founded on April 1, 1906, and the 40th anniversary of Mizuno Taiwan, established in 1986. The CHAU-SHI Series was initiated by Mr. Wong Chau-shi, one of the founders of Mercuries Group and its Honorary Chairman. Beginning in 2021, when the number of Taiwan Tour events and total prize money declined significantly due to the pandemic, Mr. Wong personally title-sponsored six tournaments, contributing NT$2 million to each event for a total of NT$12 million. His support helped establish the foundation of the Taiwan Tour during that challenging year. This year marks the sixth consecutive season of the CHAU-SHI Series under the same sponsorship model. Each event receives NT$1.5 million in sponsorship funding, and eight tournaments are scheduled for 2026. The CHAU-SHI Series also features a special Order of Merit bonus. The season-long money leader will receive an additional NT$250,000 provided by HONLIN CONSTRUCTION CO., LTD. Chairman Lin Kuo-er and will also earn a place in the following year’s Mercuries Taiwan Masters. The championship course combines the Green Mountain and Green Water nines at Bombax Golf Country Club and measures 7,182 yards.
