My quibble with this is that they should give the 3d start to either the Fister Fury or the Mouse that Roarked and give JZ the home opener. That's not just based on the "honor" concept, but also on the early April schedule.
Looking ahead, there's a series at ATL on the 4/11 -13. Gio will likely go on 4/2 (@ Mets), 4/8 (Marlins), and 4/13 (@ ATL). Whoever goes on 4/4 pitches again on 4/10 and misses the 2d Braves series. The starters on the April 5th and 6th will go twice against the Braves, going on the 11th and 12th. One of those will be Strasburg. Going Roark, Fister, Strasburg for 4/4 - 4/6 would line up Fister, Strasburg, Gio for the second Barves series. Starting SP 5 on 4/3 keeps him out of the two Barves series, would give Fister Fury and Stras two starts v. ATL, and JZ and Gio one each.
