For all Michael Te Pei Chang has accomplished, what most tennis fans will remember is the 1989 French Open.

Crippled by cramps, the 17-year-old still found a way to outlast — and outwit — Ivan Lendl in the fourth round. He beat Stefan Edberg in the final to become the youngest Grand Slam champion in history and the first American to win at Roland Garros since 1955.

A month before the 1989 U.S. Open, Chang became the youngest ever to climb into the world’s top five, and the first player of Asian descent to crack the top 10.

Thirty years later, he is on Maui to play in this weekend’s Hawaii Champions Cup at Royal Lahaina Resort. It’s the second year the Invesco — formerly PowerShares — Series is stopping in Hawaii.

In the Champions event last year at Mauna Lani, Tommy Haas beat John McEnroe in the final.

Haas is back, and the youngest in the field at 41. He opens against U.S. Davis Cup captain Mardy Fish, who replaced McEnroe on Monday. McEnroe, who turned 60 in February, has a back injury.

Australian Mark Philippoussis, 42, who won the year-long series in 2016, takes on Chang, who was born in Hoboken, N.J. He now lives in Orange County, Calif., with wife Amber — whose mother went to Punahou — and three kids, ages 8, 6 and 3.

His world revolves around them. Just ask Kei Nishikori, now in his sixth year working with Chang. When Nishikori asked Chang to coach him about six years ago, the Changs had a long conversation about the travel — 25 weeks a year — it would involve.

“We talked about it, that it might be a great opportunity to be part of a young Asian player’s career … ,” Chang said by phone. “I felt it was something that could be special and told her I know you don’t want me away from family, so if I do it, we do it together. Amber and the kids come with me to a lot of events so we’re not apart too long at a time.

“I told Kei I’d love to be able to work with you, but there’s one requirement and if you say no I probably won’t be able to work with you. My family is young and I want to be around when they’re growing up. As long as you are fine with my family I’m good to go. He got along really well with the kids, which is something I appreciate very much, as a coach but more so as a father.”

Beyond family and coaching, he still focuses on his 20-year-old Chang Family Foundation and his faith, a facet of his life that burned bright at that remarkable French Open in 1989.

Years later, Chang, who became a Christian in 1988, spoke of his lone major victory as “being a tournament that I always felt in my heart the Lord wanted me to win” because he was Chinese.

The Tiananmen Square protest in China, where hundreds died, was happening simultaneously. Chang was inspired by the protesters’ courage and believed God helped him win to “put a smile on peoples’ faces, just for a moment.”

He would ultimately win 34 titles and rise as high as No. 2 in the world, before retiring.

“My major goal when I was on tour obviously was to become the best player I could be,” he says. “At the same time, I realize my tennis talent had been given to me, it was a platform. Even today, as a coach, it’s still a platform. I was able to utilize my talent to impact lives and make a difference, make a difference for Christ. I’m a Christian, so it’s very important to me. Sometimes it’s easy to lose sight of that.

“In retrospect, I look back at something as simple as a smile or signing an autograph or picture — how far it actually goes as far as impacting a person’s life. I wish I had understood that a little better. On tour I was so absorbed by what I was trying to do and you forget the position you have. It’s now a whole different ballgame, being a father and trying to instill those important qualities in your own children.”

When he retired, he took time to speak to kids, churches and organizations. He went to seminary for a few months “to get biblically stronger.” He got married in 2008 and started playing on the Champions tour seriously and in Legends events at Grand Slams.

“I’m there already with Kei, that’s a lot of fun,” he says. “It’s great to be able to be back out playing in front of crowds, out there still playing good tennis. It’s not like in the heyday. It’s a little more fun, more interaction with the crowd, not quite so cut-throat.”

Expect that mellow atmosphere on Maui. “I don’t think any player would not want to go to Maui or any part of Hawaii to play,” says Chang, who visits annually. “It’s a great place to go and have a lot of fun.”

The event will feature two one-set semifinal matches Sunday beginning at 2 p.m., with the championship to follow. Saturday, there is a Kids Charity Clinic at 2 p.m., followed by Play with the Pros sessions and a 6 p.m. VIP Player Party. For tickets, call (866) 999-9735.
