May BPIs in Oakland, Arizona, Tampa Bay and some early warning signs.

Gordon Beckham is one of several guys that you wouldn't expect to be on a list of the most skilled bats during May.

Behind his improved knuckle-curve and changeup, Alex Wood has posted the best skills of any SP not named Kershaw during the month of May.

Relievers with 10+ holds.

No batter has improved his aggregate skills more than Jacob Lamb so far in 2016. Here's a closer look at him and others who have experienced wide skill changes from last season.

Aaron Sanchez's transition back to a starting role has been a success, as shown by his big SP skills growth from 2015 to early 2016.

A run through some bullpens where the closer BPIs are not up to snuff.

The big early start of Michael Saunders has made him a post-hype target in some leagues, but his lack of underlying support says you should be looking to sell high now.

It may be easy to buy in to the quick early start of Jordan Zimmermann. But his lack of underlying skills points to some significant regression on the horizon.

Pens for the Reds, Rockies, Angels and Twins.

In spite of continued shaky plate control, the early power surge of Nick Castellanos cements his profile as a premium young power source.
