The Toronto Blue Jays have called up right-handed pitcher Ramon Ortiz from the Triple-A Buffalo Bisons.
In a related move, the team designated outfielder Casper Wells for assignment.
The 39-year-old has allowed two runs in five innings in one start with the Bisons so far in 2013. He has posted an 86-84 career record with a 4.93 ERA in 296 games over 11 seasons with the Anaheim Angels, Cincinnati Reds, Washington Nationals, Minnesota Twins, Colorado Rockies, Los Angeles Dodgers and Chicago Cubs.
Wells was claimed from the Seattle Mariners on April 10. He did not appear in any games with the Blue Jays.
