Nelson is coming off over a year of no pitching, and has been building up and working toward taking the ball every five days ever since he starting throwing pen sessions last fall. He's also been a starter his whole career. The idea that working out of the pen is less taxing on an arm I believe is a fallacy. Getting up and warming quickly, often several times a week, can be extremely taxing on arms and, in Nelson's case, core joints. The last thing I'd want to do is put him in the pen with the expectation that he make several 3-4 appearances a week in a fireman role. And if you'r going to pitch him sparingly out of the pen to protect his arm, he may as well not even be on the team. If this team has proven anything in its 5 games so far, its that all their relievers are going to be used often. Ok but maybe it’s gonna take a while for him to strengthen the arm, to build up to 90-100 pitches. Could take longer than the month some think till ready. It could be months with another setback. Jimmy didn’t sound too concerned so maybe your right. When is he supposed to start throwing again? They had him built up to 60 with a week to go in Arizona. They haven't given any indication that he won't be starting the season in the San Antonio rotation, and their season starts Thursday. It would be nice to know what their timeline is, but it's possible they may not know for sure. I imagine it's all going to depend on how he looks and, more importantly, how he recovers between starts. How bad will the residual soreness be? If he makes his first start this weekend and is on a 60-75 pitch limit, there's no reason why he wouldn't be able to continue building with an eye on making his 2019 Brewers debut by the end of April. It wouldn't surprise me if they'd want to avoid pitching him in cold-weather games, as those can be tougher to get joints loose and break up that scar tissue in his shoulder. I don't think they would have announced him as a member of the Missions if they weren't planning on him getting work from the get-go though.
