TORONTO – The Toronto Blue Jays will call up right-handed reliever Sam Dyson from double-A New Hampshire on Thursday, a source told sportsnet.ca, the corresponding move to the demotion of Canadian Scott Richmond to triple-A Las Vegas on Wednesday.

The 24-year-old from Tampa, a fourth-round pick in 2010, started his first professional season with class-A Dunedin, going 2-0 with a 4.08 earned-run average in six starts before being promoted to the Fisher Cats, where he posted a 0.75 ERA in 15 games out of the bullpen, allowing 19 hits and eight walks over 24 innings.

While his fastball sits in the mid-90s, much like Henderson Alvarez he doesn’t strike out many batters, collecting 16 over 28.2 frames with Dunedin and only eight in 24 innings with New Hampshire. But his cumulative groundout to air out ratio is 3.34, meaning opponents have a tough time squaring him up.

The Blue Jays didn’t immediately announce Dyson’s call up Wednesday, although manager John Farrell said the move would likely be for another reliever and that the team planned to remain with an eight-man bullpen.

“Who that reliever is that would come up is yet to be determined,” said Farrell. “We’re still looking for that guy we feel like we can go to in the seventh inning when we’re down a run or two to put up a zero.”

Dyson appears to be the next man to get that chance.

Meanwhile, a release from the Dominican Prospect League says the Blue Jays have signed international free agent shortstop Richard Urena.
