Neftali Feliz made his second start of the season on April 16th. Over 5 IP, Feliz let in 2 ER while walking 2, and giving up 3 hits. He struck out 5, which means his K/9 rate is exactly 9.
Check this nice little writeup on Feliz over at Bleacher Report. Maybe Feliz is about to follow Holland to the 'pen.
