Jay Diamond over at Locksmith Sports Picks has got the Royal's ace Zack Greinke outdueling the Cardinal's newly-acquired Jeff Suppan.

Jay gives no shortage of reasons, but here are a two that may encourage you to side with him:

1. Depsite not living up to his 2009 AL Cy Young award-winning performance this season, Greinke's peripherals are still strong -- with 83 K’s and 18 walks in 96 innings and a WHIP of 1.20 -- and his last two outtings against top-10 offenses were stellar -- 17 batters struck out with zero walks and only 11 hits in 16 innings.
2. The Royals own the MLB's best batting average (.280).  This doesn't forbode well for Suppan, who, before leaving the Brewers, had a BAA of .372 and WHIP near 2.0.

Pick: Royals
