Looking at the fixture list I reckon Ballance and Root will play at most 5 first class games for Yorkshire this season. Tbf they only played 6 and 4 games respectively last year. Bairstow and Lyth will be the worries imo for the Yorkshire hierachy. I guess they'll know soon enough whether they are heading for West Indies in April and May. Who knows what kind of team West Indies will put out for that tour given the IPL and the board/player disputes.
The Ireland England ODI on 8th May is looking pretty preposterous right now. Morgan and Bopara are allowed to play the whole IPL so they'll miss the game. Test tour in West Indies ends only a couple of days earlier (+ NZ test series starts soon after) so can't see anyone from that squad been included.
Likely be a lions squad to play Ireland. Roy, Hales, Lees, Vince, Taylor, Billings, Samit Patel, Wood, Rankin, Gurney, Jordan/Finn, Tredwell/Parry, Luke Wright, Topley/Dunn
