 Biographical Information
Jô Matumoto was a pitcher with the Toronto Blue Jays chain.
After years in Japan's industrial leagues, Matumoto became a member of the Brazilian national team in 2001. In the 2002 Intercontinental Cup, the southpaw was 0-1 with a 6.30 ERA, walking 8 in 10 innings pitched. He had previously played in the 1995 Intercontinental Cup, going 1 for 10 as a backup 1B and allowing 7 walks and four runs in four innings.
In the 2005 Baseball World Cup, he went 1-1 with a 3.44 ERA and 18 strikeouts in 18 1/3 IP, walking 9, allowing 16 hits and committing three balks. That year, he was MVP of the South American Games.
In the qualifier for the 2008 Olympics, Matumoto was 1-2 with a 4.70 ERA for Brazil. He was hit hard by Canada (6 runs in 7 innings), lost a 2-1 decision to Mexico and got the win (Brazil's only victory in five contests).
The Toronto Blue Jays signed Matumoto as a non-roster invitee for 2007. He made his spring training debut on March 4 in rough form, walking four of six Tampa Bay Devil Rays batters faced and allowing a hit. It was reportedly the first time ever a Brazilian had pitched in any MLB spring training or regular season game.
Jô was assigned to the New Hampshire Fisher Cats and debuted on April 9 against the Connecticut Defenders, striking out three in two scoreless innings of work. He went 3-4 with a save and a 3.54 ERA in 45 games, allowing 74 hits and fanning 77 in 86 1/3 innings but walking 43. In 2008, he pitched 21 games for both New Hampshire (2-1, 3.77) and the Syracuse Chiefs (0-0, 3.55).
Matumoto struggled in the 2008 Americas Baseball Cup, allowing 15 baserunners and 6 runs in 7 innings. He took the loss against the Puerto Rican national team. He also played the field briefly, going 1 for 3.
