The Blue Jays transferred Sosa (wrist) from the 10-day injured list to the 60-day IL on Sunday.
Sosa will give up his spot on the 40-man roster to right-hander Jameson Taillon, whom the Blue Jays acquired in a trade with the Cubs. The 26-year-old infielder has been on the shelf since May 28 due to a right wrist contusion and was pulled off a rehab assignment in late June after experiencing a setback. He resumed taking live batting practice last week and should soon be ready to report back to an affiliate in the near future.
