In 1983, not even one year after becoming a professional, Duke won the Cleveland Open in
North Olmsted, Ohio, and became the youngest player ever to win a PBA Tour title, at 18 years and 345 days. On that day, Duke started from the No. 5 seed and worked his way up the stepladder, defeating the other four bowlers to take the championship, including a victory over the legendary
Earl Anthony in Duke's first-ever televised match. Duke would not win his second title until
1991, but his career took off from there. He won two titles in the
1993 season, including his first major at the
ABC Masters (now known as the USBC Masters). Norm completed perhaps his best season in
1994, winning five titles including his second career major, at the
Tournament of Champions, and also winning PBA Player of the Year honors. He was also the winner of the PBA Player of the Year award in
2000, capturing three titles that year, including his third career major by winning the
PBA World Championship. Duke became a member of the
USBC Hall of Fame in 2002, and was inducted into the PBA Hall of Fame in January 2009.
Parker Bohn III has since also joined the $3 million club. Duke's career earnings have now topped $3.8 million (as of 2022). Duke made multiple TV Finals appearances every season from 1990 through 2015. (He made only one TV finals appearance in 2016.) He has won at least two titles in a season nine times, including a career-best five titles in 1994. The diminutive Duke (he stands 1.65 meters, or 5-foot-5) is known for his exceptional versatility. He is generally thought of as a
stroker, either throwing the ball relatively straight or playing a hook shot from the extreme outside of the lane. But he has also shown the ability (especially earlier in his career) to swing the ball out toward the gutter and bring it back like a
cranker when necessary. This gives him the advantage of being able to score well on most of the PBA's multiple oil patterns.
2007–08 season The
2007-08 season started slowly for Duke, as he battled illness on top of a series of injuries through the first half. Standing 51st in points and with his Tour exemption in jeopardy, he put together a furious finish by winning two majors in the final five weeks of the season. On February 24, 2008, he won his second career PBA World Championship to lock up a 2008-09 exemption. Then on March 30, he won the
U.S. Open and joined
Mike Aulby and
Billy Hardwick as the only bowlers to ever complete the coveted PBA "Grand Slam," in which a PBA bowler wins the U.S. Open, World Championship, Tournament of Champions, and USBC Masters at least once in a career. He is also one of only nine bowlers in history to complete the PBA career Triple Crown, in which a player wins the PBA's "original" three majors (U.S. Open, Tournament of Champions, and World Championship).
2008–09 season Duke began the
2008-09 season by, again, winning the PBA World Championship. Continuing on his success from the previous season's sweep of the final two majors, he accomplished something never before done by any professional bowler: win three consecutive major tournaments. The streak ended when he failed to make the TV finals for the 2009 Tournament of Champions. On April 5, 2009, Duke narrowly missed an opportunity to become just the fifth bowler to repeat as champion at the U.S. Open. He qualified as the #1 seed, but was upset in the final by
Mike Scroggins, 191–173. Duke eventually did win a second U.S. Open on February 27, 2011.
Later career Duke's 37th title on the PBA Tour came in 2012 at the
Dick Weber PBA Playoffs. He joined the PBA50 Tour (formerly PBA Senior Tour) in 2014, while continuing to compete in selected events on the standard PBA Tour. His 38th title on the standard PBA Tour came in the 2015
Mark Roth-
Marshall Holman PBA Doubles Championship, where he partnered with
Wes Malott for the win. He captured his 39th PBA title on February 24, 2019 at the PBA Indianapolis Open, defeating
Jason Belmonte in the title match. A month shy of his 55th birthday, Duke became the third oldest player to win a standard PBA Tour event, behind
John Handegard (57) and
Buzz Fazio (winner of two titles at age 56). One week later, he won his 40th PBA Tour title at the PBA Jonesboro Open, becoming the third player in history to win 40 PBA Tour titles (after
Walter Ray Williams Jr. and
Earl Anthony). It was also the first time in Duke's career that he had ever won PBA titles in back-to-back weeks. A testament to Duke's versatility, both victories were on mixed lane conditions, with the left lane and right lane featuring different lengths and layouts of oil. On April 2, 2022, the 58-year old Duke claimed the top seed (out of 420 competitors) at the
USBC Masters. Seeking to become the oldest player to win a PBA Tour title and oldest to win a major, he was defeated in the April 3 final by
Anthony Simonsen, 219–216. Prior to the finals, Duke announced that unless he qualified for the upcoming
PBA Tour Playoffs (he needed a win to qualify), he would be retiring from full-time competition on the PBA Tour. He will still bowl in
PBA Regional Tour and PBA50 Tour events. Duke made his final televised PBA Tour appearance at the 2022 PBA League Elias Cup Finals in
Portland, Maine on July 10. He reprised his role as the player/manager for the Dallas Strikers, bowling lead-off for the team. The Strikers made it to the final match against the Portland Lumberjacks. After Duke's doubles partner
Wes Malott clinched the tournament for Portland with a spare in the 10th frame of the final game, he yielded his fill shot to Duke. Poetically, Duke closed out his full-time PBA Tour career with a strike. Duke's departure from the PBA Tour was met with much emotion from bowlers and fans alike, so much so that the hashtag
#ThankYouNorm began trending throughout the community shortly before he made his final TV appearance. Despite starting the 21st century at age 36, Duke ranked #3 on the PBA's 2025 "Best 25 PBA Players of the Last 25 Seasons" list. The ranking was based on a points system that took into account standard titles, major titles, top-five finishes and Player of the Year awards. ==PBA50 Tour==
