Perdomo will be a very deep sleeper going into the 2018 season, but don’t be surprised if he becomes a breakout star with the rebuilding Padres. In 2017 he was second out of all qualified pitchers with a 61.8 ground ball rate, and was one of only two pitchers to have a ground ball rate above 60%. This should help limit home runs, which is key when I do my rankings.
Now one of Perdomo’s problems is the fact he gets no run support from his team. The Padres are arguably the worst team in baseball, and it doesn’t help him add W’s to his resume. Another big problem for him last year was the fact that batters only made soft contact against him 18.1% of the time. This was the 21st worst out of all qualified pitchers last season. Probably the worst thing about Perdomo’s game is his lack of strikeouts. With a 8.8% swinging strike rate, I don’t see much changing come 2018. He may be able to get his K/9 over 7 as he still has time to improve his game at the young age of 24.
It seems like Perdomo has had a lot of bad luck the past couple of seasons. his career .333 BABIP shows me that opposing batters seem to have had a lot of luck. He will probably not be a top 30 starting pitcher option in 2018 due to his lack of strikeouts and wins, but he could be an unseen sleeper who could help your ERA.
