Pirates' Miguel Yajure: Sent down after spot start

Yajure was optioned to Triple-A Indianapolis on Tuesday, Justice delos Santos of MLB.com reports.

He walked a tight rope in his spot start Monday against the Nationals, tossing four scoreless innings while allowing four hits and three walks and recording zero strikeouts. Yajure obviously has some work still to do in the minors, particularly figuring out how to miss more bats (4:9 K:BB in 14.1 MLB innings), if he is going to make it as a big-league starter.
