The Blue Jays have been red-hot since acquiring Troy Tulowitzki and David Price, moving into the top five for the first time all season.
The National League reigns supreme this week with the Cardinals, Dodgers and Pirates sitting atop our rankings.
The Royals improve their chances at another World Series appearance by adding a true No. 1 to their rotation, while the Reds stock their farm system with young, successful arms.
The Pirates only need Aramis Ramirez to match Josh Harrison's disappointing slash line at third base to make this trade a success.
The Astros were smart to jump on Scott Kazmir, who bolsters their rotation without coming at the cost of someone like Cole Hamels or Johnny Cueto.
