FIVE TRENDING UPWARD
Blue Jays
2014 wins: 83
Offseason wins acquired: +9.7
The Blue Jays have had one of the loudest offseasons in all of baseball thus far. They landed Josh Donaldson (7.4 WAR) in a trade with the A's, and they added Russell Martin (5.5) through free agency. They also pulled off a trade with the Mariners Wednesday night, adding a win by shipping J.A. Happ (1.4) to Seattle for Michael Saunders (2.4).
But the Blue Jays' sky-high WAR among the players they've added is almost certainly set to drop a bit. Assuming they traded for Saunders because they are conceding that Melky Cabrera and Colby Rasmus will be headed elsewhere, their WAR will decline by four when the outfield pair officially depart. Toronto may also lose closer Casey Janssen, and for as much as they've added in terms of offense, it was the pitching staff -- with an ERA of 4.00 -- that was their biggest downfall last year.
