Born in the United States of America, Mathew Thomas Belisle is a professional baseball player who plays as a pitcher. Belisle began his career in high school and his strong performances for the McCallum High School ensured that he got drafted straight out of high school in the second round of the 1998 MLB Amateur Draft by the Atlanta Braves.
Belisle began playing for the Atlanta organization in the Rookie leagues, with the Danville Braves. By the following year, he gained promotion to the A-League to play with the Macon Braves. At Macon, Belisle had a 2.38 ERA in 15 starts and that got him into the Advanced A-League to play for the Myrtle Beach Pelicans, in 2001, where he started 12 games at an ERA of 3.43. In 2002, he was promoted to the AA-League and he spent the that, and the next, year playing with the Greenville Braves.
In August of 2003, Belisle was traded out to the Cincinnati Reds in exchange for Kent Mercker, As soon as Belisle landed at the Reds, he was assigned to the AAA-League to play with the Louisville Bats. In September, he was called up to play for the Cincinnati Reds and on his debut, pitched 2 innings while giving away a home run and a walk. He ended the season with 6 more games although as a relief pitcher and had a 1-1 record with a 5.20 ERA. That was to be his last piece of action in the MLB for a year as he spent 2004 with the Louisville Bats.
He ended 2004 with a 5.26 ERA and 9-11 win-loss record in 28 starts for the Bats. In 2005, he was recalled to the Cincinnati Reds and this time, he spent the whole year pitching out of the bullpen.
