The biggest catalyst for each team:

Blue Jays: Sure, newcomers Troy Tulowitzki and David Price have done their parts, but Josh Donaldson has been even more productive. In this 10-game span, Donaldson is hitting .324/.444/.784 with 5 homers and 10 RBI, cementing his status as an AL MVP candidate.

Cubs: Manager Joe Maddon's decision to insert rookie Kyle Schwarber's bat into the lineup stole the headlines (Schwarber has 2 homers, 2 doubles and 8 RBI in his past 8 games). But right fielder Jorge Soler is hitting .323 with a .417 on-base percentage and 8 RBI in his past 9 games and just had a 10-game hitting streak snapped Wednesday.

Mets: As first baseman Lucas Duda cooled, center fielder Curtis Granderson caught fire. In his past 10 games, Granderson has 3 homers, 10 RBI, 7 runs scored and a .513 slugging percentage. Remember, incoming slugger Yoenis Cespedes didn't hit his first homer for New York until Wednesday.
