Cubs' Caleb Kilian: Sent down to Iowa

The Cubs optioned Kilian to Triple-A Iowa on Saturday, Jared Wyllys of AllCHGO.com reports.

Kilian gave up eight hits and a walk over 3.2 innings during spring training. The 27-year-old righty owns a career 9.22 ERA and 2.01 WHIP across 27.1 MLB frames, and his 40-man spot could be in jeopardy soon.
