Woodruff started 4 games this year on 19 appearances, he was a reliever at the mlb level most of the year. At what point are you trying to claim he abandoned his changeup as he was shifted to relief? What's far more likely is you are just making stuff up. Just like his fastball having no movement is made up, most of us watch these game...if you try to make stuff up to drive your point home, others will catch it and call you on it. I've seen Woodruff throw plenty of changeups in September and the post season, I've also seen him throw a fastball generally with arm-side movement...as in not straight. The only thing I've noted that wasn't simply made up, is that he had a bit of a bump in fastball velocity out of the bullpen. Fangraphs had him at 94.7 in 2017(when he only started) and 95.8 in 2018 which he was mostly a reliever. You could probably say he's 94-96 as a starter and 95-98 as a reliever. Those couple ticks matter, but his ability to locate was far more important though than that extra 1-2 ticks. I don't understand why it just can't be accepted that some posters like Woodruff more than they like Peralta. I'm one of them. I really like Peralta, but I think he has more flame-out potential, mostly because he is small. Woodruff, on the other hand, is pretty much the body type you see when you look up "workhorse starting pitcher" in the encyclopedia. Now, that doesn't mean that he will make it and Freddy won't. All it means is that I personally like Woodruff's upside better, and if they were going to trade one, I'd prefer it be Peralta.
