Looking at bullpen skill sets in OAK, MIA, DET, CLE and SEA.

Fact/Fluke Spotlight returns, and shines its beams on the hot start of Mike Moustakas.

Toolsy LA rookie Joc Pederson posted the best power skills (250 PX) and highest walk rate (23% bb%) of any hitter in MLB during April—indicators that suggest his hot April was no fluke.

Corey Kluber has followed up his 2014 Cy Young season with a 4.62 ERA through five starts. Any cause for concern? Plus Jason Kipnis, Dustin Pedroia, Clay Buchholz, and Marcus Semien.

Underneath Clay Buchholz's ugly surface stats in April were some top-tier base skills that make him a premium early-season buy-low target.

A major free agent hits the market. And some baseball players.

Miguel Cabrera's HR total tumbled last season, and the injuries are starting to pile up—has he entered decline at age 32? Also, Boxberger, Shoemaker, Castro, Weeks.

Aroldis Chapman continues to pile up the strikeouts, while leaving little doubt that he's the most dominant closer in the game. Plus Ryan Vogelsong, Jerome Williams, Ian Desmond, and Jayson Werth.

Can Craig Kimbrel post his fourth consecutive sub-2.00 ERA season? Plus Angel Pagan, Tony Watson, Eric Young Jr., and Wily Peralta.

Mike Trout looks to improve on his impressive start by striking out less. Also Sabathia, Avila, Herrera, and Smoak.
