Entering spring training, one of the more intriguing things to watch was going to be the Pittsburgh Pirates pitching staff. Even more so, the team and fans were going to get a look at top pitching prospect Mitch Keller. Keller ranks as MLB Pipeline’s number one overall prospect for the Pittsburgh Pirates. Also, he ranks as the number 19 overall prospect along with being the number four right-handed pitching prospect.
With all those high rankings, the expectation for Keller is very high. Keller reached Triple-A last season and had a rough start, but pitched very well during his final five starts or so.
