Should probably update a previous post now that Mortensen and Hammel are gone.
stats: ERA - H/K IP - WHIP - GO/AO
#1 DeLaRosa; 3.51 - .81/.88 - 1.19 - 1.02 (Will not return to May/June, so the starting rotation would be the five below)
#2 J. Chacin; 3.62 - .87/.77 - 1.31 - 2.14
#3 J. Nicasio; 4.14 - 1.02/.81 - 1.27 - 1.40
#4 Pomeranz; 5.40 - 1.04/.71 - 1.31 - 1.17
#5 J. Guthrie; 4.33 - 1.02/.63 - 1.34 - 0.93
#6 Moscoso; 3.38 - 0.80/.58 - 1.09 - 0.38
#7 Outman; 3.70 - 1.06/.60 - 1.46 - 0.73
#8 A. White; 7.01 - 1.21/.71 - 1.69 - 1.18
#9 Chatwood; 4.75 - 1.17/.52 - 1.67 - 1.34
I'd guess Guthrie is already penciled into the #3 spot in the rotation, though I have him as the 4th-best. He's not a front-line starter, but a veteran innings-eater that's almost guaranteed to pitch into th 6th and give rest to a bullpen that could be taxed if the 1-2 SP'ers struggle.
I'd guess Moscoso is likewise penciled into the #5 spot and is the 5th-best. His H/IP and WHIP could easily rise .30 and his ERA +1.00 as he pitches lower in the zone to reduce his astronomically high flyball rate. But like Guthrie, Moscoso is good at working innings to prepare the 'pen for the top of the rotation.
I'd guess Pomeranz will determine who pitches in the #1-2-4 spots. None of his stuff worked last year, but if he got that figured out, he could be our opening day ace. If he's still struggling/developing, than he probably falls to the #4 spot. I'm not expecting big strides from Chacin or Nicasio this spring and think last year is a good example of their pitching abilities.
So, despite the year-old stat ranking above, I'd list out opening day rotation as ----
#1 Chacin
#2 Pomeranz (L)
#3 Guthrie
#4 Nicasio
#5 Moscoso
