Nationals' Tanner Roark: Set to open season in rotation

Roark is one of the top internal candidates to fill the two openings in the Nats' rotation in 2016, Bill Ladson of MLB.com reports.

Roark and Joe Ross would replace Jordan Zimmermann and Doug Fister in the rotation as things stand, although GM Mike Rizzo could still bring in another starter through trade or free agency, and a big spring from a prospect like Lucas Giolito could create a job battle. Roark had a 2.85 ERA and 15 wins in 31 starts in 2014, so the Nats are comfortable with him taking a regular turn.
