No, it's not Brett Lawrie. To make room for Darren Oliver the Blue Jays have designated Mark Teahen for assignment. The Blue Jays will trade or release Teahen after the prescribed waiting period, which is ten days I think.
Teahen's status change is not a surprise, there is no spot for him on the 2012 squad. I assume AA has been trying to deal him with no success. The Jays might still deal him to the team that will absorb the most of his salary but don't expect anything back unless the Jays eat all of his contract. Teahen has value to some teams but not as his current salary of $5.5 million.
Consider this your new Blue Jay thread for this week or until there is more news.
