I think barring a huge rash of SP injuries, Burnes won't be in Milwaukee until he clears the June Super 2 cutoff as well - there are going to be other rotation options the Brewers can mess around with and give opportunities (Guerra, Miley) while biding their time. With Burnes being a college draftee, I'm a bit less concerned about service time clocks since his arm already has the added mileage of 3 years of college pitching on it. With college pitchers who display solid command and above average stuff, I prefer the strategy of pushing them through the minors until they struggle, and if they don't struggle they should be pitching in the majors. However, their innings workload still needs to be gradually increased, as I feel like they've grown accustomed to logging 100-150 IP for several years between college and minors, but need a couple MLB seasons to jump up over 175IP. Too often a talented college pitcher hits the big leagues fast and immediately is going close to 200+ innings - particularly for teams in the hunt for a playoff spot - only to have a setback the following season due to an arm injury. Pitchers and injuries are so fickle, if you have a potential #2 or better starting pitcher logging innings at AAA, as soon as that Super 2 cutoff passes you get him in the MLB rotation - forecasting what a pitcher is 6 years from now is impossible. A mid June callup would essentially be 2 years of minor league development for Burnes, and frankly if he's healthy I wouldn't much care what his #'s in CO Springs are - he's probably ready to pitch in the majors. Depending on how the first two months of this season unfold, I think there's a solid chance the starting rotation could have a bunch of different names in it by August. Aside from Burnes and Nelson, it wouldn't surprise me for Peralta to get a shot - and if the wheels fall off the mlb season I strongly feel like the Brewers need to use the 2nd half of this year to get Hader stretched out and starting at the MLB level, too. Rotation options of Nelson, Hader, Burnes, Woodruff, and Peralta to go along with Anderson, Davies, and Chacin is enticing.
