In this post I am going to cover some prospects that are being grossly undervalued. I will not be going over some of the names I covered in my post about underrated prospects outside the top 100 in the preseason, so if you’d like to read that article you can click here.
Corbin Martin, RHP, Houston Astros
No. 4 Prospect According to Baseball America
Martin was taken in the second round by the Astros in the 2017 draft. He features not one but three plus pitches in his fastball, slider, and changeup, which has helped him post a 16.4% swinging strike rate at High-A and a 13.0% swinging strike rate at Double-A this season. The 22-year-old has also been inducing a lot of ground balls and infield fly balls since his pro debut, which should help him keep his home run rate down. There seem to be some questions concerning his command, but these concerns should lessen as he matures. With already superb peripherals and a great pitching coach in Brent Strom, Martin looks like he could be a deadly force at the major league level.
Erich Uelmen, RHP, Chicago Cubs
No. 27 According to Baseball America
With sidearm pitching mechanics, Uelmen has been able to induce a lot of ground balls. In fact, he averages nearly four ground balls per fly ball. That's insane, but that's not all he does well. He also owns a swinging strike rate of 15.5% at Single-A this season, which has helped him post an impressive 25.6% strikeout rate. His command is a little worrisome, but this 22-year-old looks like a quality buy-low option in dynasty leagues.
Kyle Wilcox, RHP, Seattle Mariners
Ranked Outside the Top 30 According to Baseball America
Wilcox was a little bit older than his competition at Single-A to start the season, but when you strikeout out nearly half the batters you face you have my attention. His batted ball profile and command are both worrisome, and his changeup still needs some work. With a 45.2% strikeout rate, however, Wilcox at least warrants our attention.
Nick Neidert, RHP, Miami Marlins
No. 5 According to Baseball America
Neidert lacks a quality fastball, but he makes up for it with excellent command and a quality slider and changeup. These factors have helped him post a spectacular 4.63 strikeout-to-walk ratio at Double-A this season. This ability to limit walks while also striking out hitters could help him make his way into the Marlins' rotation.
Travis MacGregor, RHP, Pittsburgh Pirates
Outside the Top 30 According to Baseball America
Do you like fantastic strikeout-to-walk rates? Then MacGregor is the guy for you!
In his 29 innings at Single-A this season, MacGregor is striking out 33.3% of batters while only walking 5.4%. This is due to improved velocity from the seasons prior and a Gallo-like swinging strike rate of 18.4%. If these trends continue we could be looking at the next breakout star.
Cionel Perez, LHP, Houston Astros
No. 13 According to Baseball America
After struggling to strikeout batters in his first professional season, Perez came back with something to prove, and boy did he ever. So far at Double-A this season he is striking out nearly 30.0% of batters he has faced. With a pretty impressive four-pitch arsenal and 14.7% swinging strike rate, there is no reason to believe that his early season success cannot continue.
