...here we go with my top 10 lefty/right duos (considering only one pair per organization):
1. David Price/Wade Davis, Rays
Yes, Tampa Bay's pitching is going to get even better.
2. Derek Holland/Neftali Feliz, Rangers
Just 17 months ago, Holland was in junior college and Feliz was a Brave.
3. Brett Anderson/Trevor Cahill, Athletics
Both were lights out in Double-A and Olympians at age 20.
4. Brian Matusz/Chris Tillman, Orioles
Matusz was the best pitcher in the 2008 draft; Tillman was part of the Erik Bedard heist.
5. Madison Bumgarner/Tim Alderson, Giants
The 2007 first-round picks each won full-season ERA titles as 19-year-olds.
6. Cole Rohrbough/Tommy Hanson, Braves
They're two examples of how well Atlanta mastered the draft-and-follow process.
7. Ross Detwiler/Jordan Zimmermann, Nationals
They're the two best arm from Washington's pitching-heavy 2007 draft crop.
8. Sean West/Ryan Tucker, Marlins
West has rebounded from labrum surgery; Tucker could be Florida's future closer.
9. Franklin Morales/Jhoulys Chacin, Rockies
Both had stunning years, though Morales was as disappointing as Chacin was surprising.
10. Casey Crosby/Rick Porcello, Tigers
Crosby is rebounding from Tommy John surgery, while Porcello won the FSL ERA title.
