Jake Mailhot from FanGraphs looks at Bailey Ober's pitch mix and thinks he has potential to continue to improve. Specifically, he shared some charts on Ober's slider before and after he made some changes to it in mid-August. He's always had good extension, but he also has a low release point.

Nice. Thanks. I am hopeful. 

That is a nice article, thanks for sharing!  I am probably lower on Ober than most but was happy to see him do well last year and we need him to be just a little bit better this year.  Looks like he has the pitches to do it, just has to execute them in a good order to keep hitters off balance.

Since the team (and fans) are depending so much on pitching prospect development, it is good to see favorable articles from outside the Twins organization and twins daily.
