National League Central rivals, specifically the I-90 enemies, have recently made additions to improve the top of their rotations.
The Crew made a six-player deal that brought former AL Cy Young Zack Greinke into a rotation that already had right-handers Shaun Marcum and Yovani Gallardo, in addition to left-hander Randy Wolf. Each of these members have enjoyed recent success at the major league level and will be able to work deep enough into games to help keep the bullpen rested.
The Cubbies brought in Matt Garza in an eight-player deal that sent four of the Cubs' top prospects to Tampa Bay. Garza joins Carlos Zambrano, Ryan Dempster and others in another rotation that needs to lead their team.
The two trades involved plenty of guys changing uniforms and therefore will be scrutinized for years to come as each player progresses with their new team. The fact that the Brewers and Cubs made deals for ace pitchers, within weeks of each other adds more intrigue to the transaction. Each team had to unload a good portion of their farm system, and that begs the question of whether or not each team got what they paid for.
