The Toronto Blue Jays have promoted right-handed pitcher Sam Dyson to the big leagues.

The Blue Jays announced Thursday that the club selected Dyson's contract from the AA New Hampshire Fisher Cats. The Jays also optioned Canadian right-hander Scott Richmond to AAA Las Vegas to make room for Dyson.

Dyson, 24, started the 2012 season with class-A Dunedin, where he was 2-0 in six starts with a 4.08 earned-run average. Since joining New Hampshire the six-foot-two, 205-pounder has posted a 0.75 ERA in 15 relief appearances with three saves.

The Tampa, Fla., native has a combined record of 2-0 with three saves and a 2.56 ERA with 13 walks and 24 strikeouts in 52 2/3 innings.

Dyson was selected by the Blue Jays in the fourth round of the 2010 first-year player draft out of the University of Carolina. He then missed the 2011 season recovering from Tommy John surgery on his right elbow.
