Royals Option Rookie Starter

The Kansas City Royals are sending him back down to the minors again.

The club has optioned starter Max Castillo to Triple-A Omaha. 

With the return of Zack Greinke to the rotation, there was just not a spot on the roster for Castillo anymore. He last pitched in a start on Sunday against the Detroit Tigers, allowing two earned runs, five hits, one walk and five strikeouts over 4.2 innings. 
Castillo has posted a strong 2.97 ERA, 0.99 WHIP, and 28 strikeouts over 30 innings pitched in his major league debut this season. In 11 games, he's made four starts. 

In the minors this season, the twenty-three-year-old has registered a 3.43 ERA, 1.19 WHIP, and 40 strikeouts over 39 innings. He's appeared in nine games, starting six of them.
