Orioles executive vice president Dan Duquette said Tuesday that even with their big contracts, Wei-Yin Chen and Tsuyoshi Wada could begin the season in the minors. Roch Kubatko of MASNSports.com was told by a team official last week that Chen and Wada "contractually figure" to be in the rotation, but it's clear that Duquette is willing to be flexible. As of now, Chen, Wada, Jason Hammel, Zach Britton and Jake Arrieta look like the favorites for the rotation, though Tommy Hunter, Brian Matusz, Dana Eveland and Chris Tillman are among the potential alternatives. None look like palatable options in standard mixed leagues.
