The Oakland Athletics have optioned starting pitcher Jesse Hahn to Triple-A Nashville, the club announced, allowing left-hander Felix Doubront to assume the role as the fifth starter to at least open the season. Most likely taking Doubront's place in the bullpen is right-hander Ryan Dull.
The A's starting rotation therefore will start the year as Sonny Gray, Rich Hill, Kendall Graveman, Chris Bassitt, and Doubront. In the bullpen are Sean Doolittle, Ryan Madson, John Axford, Liam Hendriks, Marc Rzepczynski, Fernando Rodriguez, and Dull.
