Due to the gruesome ankle injury Buster Posey (C, SF) suffered in May 2011, we've had an extra-long wait to determine the proper context for his impressive 2010 Rookie of the Year campaign. Through the first four months of 2012, it sure looks legit.

We find batters whose PX since May 28 have been far higher (like Jason Kubel, pictured) or lower than before that date.

The signing of Rafael Soriano (RHP, NYY) prior to the 2011 season was not a popular move given the depth in the Yankees bullpen at the time. Soriano's struggles during last season did nothing to silence his critics.

This former first round pick is finally showing signs of tapping into his upside, due in part to a refined pitch mix.

Celebrating the 2012 Olympiad with another collection of potential free agents and a shameless tie-in.

There are many reasons why the Washington Nationals pitching staff leads the NL in ERA, WHIP batting average against. And Jordan Zimmermann (RHP, WAS) is among them. With a 2.35 ERA and 1.09 WHIP, the 26-year-old continues to build on last year's breakout season.

With a power surge in the second half of 2011, Billy Butler (DH, KC) was on many breakout lists going into this season. Sure enough, with over two months left, he’s close to matching his career high in HRs.

Nothing changes teams fortunes more than deadline deals involving closers. Who might move?

It might be difficult to remember that just four months ago, Ryan Braun's (OF, MIL) 2012 season was a great unknown. Though he had a history of stable and elite skills, his performance level was stained (legitimately or not) by a PED allegation. How would this roto-god respond on the field?

Five batters, including Robinson Cano (pictured) are whacking more line drives than other players but getting fewer hits.

Many pitchers continue to try, but the only thing capable of shutting Dustin Pedroia (2B, BOS) down apparently is injury. Pedroia remains one of the AL's top second basemen, but his struggle with a thumb injury this season has cut into his production significantly...
