MOST/LEAST IMPROVED

Fangraphs takes a stab at guessing which team will be the most improved in 2014. It also rates the teams likely to fall the most. It is based upon estimated WAR, and last season success/failure weighs heavily into the rankings.

The ten most-improved teams:

• Astros, +18 WAR
• Phillies, +12
• Mariners, +11
• Marlins, +8
• Yankees, +8
• Blue Jays, +8
• Padres, +8
• White Sox, +6
• Twins, +5
• Brewers, +4

The ten lease-improved teams:

• Red Sox, -16 WAR
• Tigers, -14
• Rays, -8
• Braves, -8
• Athletics, -8
• Reds, -7
• Rangers, -7
• Royals, -6
• Orioles, -6
• Pirates, -5

 The Astros are not going to win their division. What may happen is that the Red Sox come back down to Earth and struggle for a wild card spot in the AL East. The Tigers could be caught in the AL Central. The AL West will be interesting with the Mariners off season and the projected fade of the A's.

It also speculates that teams not mentioned will remain basically the same, like the Cardinals (division winners) and the Cubs (division bottom feeder).
