The Toronto Blue Jays have recalled right-handed pitcher Bobby Korecky from triple-A Buffalo and optioned outfielder Kevin Pillar to the Bisons.
Korecky has appeared in one game for the Blue Jays this season, working 1 1/3 scoreless innings against the Kansas City Royals on May 30.
He is 3-1 with six saves and a 0.26 earned-run average in 25 games at Buffalo.
Pillar is batting .243 in 24 games with Toronto with no home runs and two runs batted in.
He singled home the winning run in the ninth inning of Monday's 5-4 victory over the Minnesota Twins.
Pillar, who bats right, has been used mainly in centre field along with Anthony Gose while incumbent centre-fielder Colby Rasmus recovers from a sore right hamstring.
Blue Jays manager John Gibbons says he didn't expect to use Pillar in the next several days as the Blue Jays continue a stretch of six straight games against right-handed starters.
