"It's a great ballclub and I know my family is happy," Wells said. "I'm from upstate New York, so they will be able to see a lot of games."
Wells owned a .237 career average in 194 at-bats entering Friday's series opener against Kansas City. He has played parts of the last five seasons for the Tigers and Mariners.
"He has always had success hitting left-handed pitching," Blue Jays manager John Gibbons said. "He can play all three outfield positions and is a good baserunner. He's just a good baseball player."
