Michael first joined the PBA in 1994, competing as a Regional pro. He was named the PBA West Region Player of the Year in 1997, and has won 21 PBA Regional titles to date. He bowled in selected PBA Tour events in the 1996 and 1997 seasons, before becoming a full-time bowler on tour in the 1998 season. In the 2002-03 U.S. Open, he finished runner-up to Walter Ray Williams, Jr.
Early in the 2007–08 PBA season, he won the Lake County Indiana Classic in Merrillville, Indiana. In doing so, he won his first tournament in 200 attempts and qualified for the Tournament of Champions. Later that season, he became the second bowler in history to win his first PBA title and the Tournament of Champions major in the same season, joining Joe Joseph who accomplished the feat in 1962. In the Tournament of Champions, as the number 1 seed, he completed a stunning comeback by defeating Chris Barnes in the final by one pin, after trailing by 53 pins in the sixth frame. A finger injury cut his season short as he was forced to miss the final seven events of the year, but he did manage to bowl in the Motel 6 "Roll to Riches" event in April 2008.
Injuries again curtailed his 2008–09 season, as he was only able to compete in seven events. But he returned to start the 2009–10 season and made the TV finals for the PBA Viper Championship at the World Series of Bowling. He won his third PBA title at the Mark Roth Classic in Allen Park, Michigan on January 26, 2013.
Haugen won his fourth PBA title on November 2, 2014 in the Scorpion Championship at the World Series of Bowling in Las Vegas, Nevada. His fifth title was earned at the 2016 PBA Xtra Frame Gene Carter's Pro Shop Classic in Middletown, DE.
Through the end of the 2016 season, he had rolled 31 perfect 300 games in PBA events. He has accumulated over $725,000 in career PBA Tour earnings.
While still competing in selected events on the regular PBA Tour, Haugen also joined the PBA50 Tour (formerly PBA Senior Tour) in the 2017 season. He won his first PBA50 Tour title in a major tournament: the Suncoast PBA Senior U.S. Open held on June 16, 2017 in Las Vegas, NV.

He made good on his promise during his post-tournament interview, and Truong accepted.
