Hector Perez, RHP
Age: 22
After signing as an 18-year-old, Perez has quickly made up for lost time. He recently had been promoted to Double-A Corpus Christi after minor improvements in his delivery helped him show improved control in his final month with high Class A Buies Creek. Perez always has a mid- to upper-90s fastball that can blow some hitters away, but it’s less effective when he has bouts of wildness. His control wavers from below-average to average. Perez throws an extremely hard, 88-90 mph slider with modest depth and he’s improved his splitter that serves as his changeup. At the least, he should be an effective power reliever for the Blue Jays. But if he can continue to improve his secondary pitches and his control, he has the makings of a potential mid-rotation starter.
David Paulino, RHP
Age: 24
Paulino has long been one of the most talented pitchers in the Astros' farm system, but he also has been one of the most frustrating. Between injuries and a suspension, the 6-foot-7 Paulino has thrown just 273.1 innings in eight pro seasons and he’s never thrown more than 90 innings in a season. Paulino has missed time with Tommy John surgery, a disciplinary suspension, elbow soreness, bone chips in his elbow and an 80-game suspension for testing positive for a performance-enhancing drug.
This year, he’s missed most of the season with a shoulder injury, although he has returned to action and was working on a rehab assignment in the Rookie-level Gulf Coast League. If Paulino tests positive again, he will be suspended for a full season. Paulino’s fastball isn’t as firm as it was at his best in 2015-2016, but it’s still a potential plus pitch with plenty of angle and velocity. His curveball gives him a second plus offering. His changeup has even flashed plus as well, although getting all three synced up has been difficult because Paulino has missed so much time. Paulino is a perfect buy-low candidate to acquire in a trade. His struggles to stay healthy may prevent him from reaching his still-lofty ceiling, but if he puts it all together he could still be a mid-rotation starter or an elite reliever.
