Nick Masset is a former professional baseball player who played as a relief pitcher in Major League Baseball (MLB) for several teams. He was born on May 17, 1982, in St. Petersburg, Florida, and attended Pinellas Park High School. He was drafted by the Texas Rangers in the eighth round of the 2000 MLB draft.

Masset made his MLB debut on April 4, 2006, for the Texas Rangers. He played for the Rangers until 2008, when he was traded to the Cincinnati Reds. Masset played for the Reds from 2009 to 2013, during which he had his best seasons. In 2010, he had a 3.40 earned run average (ERA) and 79 strikeouts in 76 innings pitched. In 2011, he had a 3.71 ERA and 62 strikeouts in 56 innings pitched.

Masset's career was hampered by injuries, particularly to his shoulder. He missed the entire 2012 season due to a shoulder injury and underwent surgery. He returned to the Reds in 2013 but struggled with his performance, posting a 4.18 ERA and 46 strikeouts in 42 innings pitched.

After the 2013 season, Masset became a free agent and signed with the Colorado Rockies. He played for the Rockies in 2014 and had a 5.80 ERA and 36 strikeouts in 40.1 innings pitched. He became a free agent again after the season and signed with the Miami Marlins for the 2015 season. He struggled with injuries and performance, posting a 4.71 ERA and 23 strikeouts in 21 innings pitched.

Masset's career in MLB ended after the 2015 season. He finished his career with a 4.06 ERA and 394 strikeouts in 427 innings pitched. He played for five different teams during his career: the Texas Rangers, Cincinnati Reds, Colorado Rockies, Miami Marlins, and Atlanta Braves (although he did not appear in a game for the Braves).

In addition to his MLB career, Masset also played in the minor leagues for several years. He played for the Rangers' minor league affiliates from 2000 to 2005, the Reds' minor league affiliates in 2008 and 2013, and the Marlins' minor league affiliates in 2015.

Overall, Masset had a solid career as a relief pitcher in MLB, but injuries prevented him from reaching his full potential. Despite this, he was able to play for several teams and contribute to their success during his time in the league.
