Over the monster...
Bryan Mata, RHP
Strengths: Mata has been one of the more intriguing arms in the system for a few years now, quickly bursting on the scene despite receiving a paltry $25,000 signing bonus out of Venezuela in 2016. He’s done very little but perform at each stop along the way, however, and made his way up to Double-A as a 20-year-old in 2019. It’s Mata’s stuff that jumps off the page, as he comes equipped with a fastball that can get up to the high 90s and sits in the mid 90s, along with a couple of solid breaking balls and a changeup that has flashed some potential. That hasn’t always resulted in big strikeout totals, though he did get his rate over a K per inning in 2019.
Weaknesses: While the stuff is certainly intriguing for Mata, as is the quick trajectory through the system, there are still some concerns. Chief among them would be his command, which has been inconsistent throughout his career. He’s been able to make up for that at the lower levels, but that becomes harder as he faces more advanced hitters. Especially as he’s gotten bigger and added that velocity, he’s had a harder time consistently commanding his pitches. Along with that, consistency with his delivery has been an issue that’s contributed to both the command issues as well as some injury issues throughout his career. All of that has combined to provide some pause that his ultimate future will be as a starter.
Path to the majors: Mata will turn 22 next May, so he still has time to develop. However, despite a 5.03 ERA over 11 starts in Portland in 2019, Sox Prospects still has him projected for Triple-A Worcester in 2021. That makes sense after he spent all of last summer at the Alternate Site and was mostly impressive there. Assuming he does start in Worcester, that puts a 2021 debut on the table, though that would have to come with a strong performance in the minors. My guess is he’ll get a shot towards the end of the year, but it’s no guarantee. Either way, I’d predict his first chance to make a real impact will come in 2022.
Jay Groome, LHP
Strengths: Groome is, to me, the most interesting player on this list as a former top prospect — at one point leading up to his draft year he was discussed as a potential 1-1 pick — who just hasn’t been able to stay healthy. He still flashes that potential, though, and he did so fairly consistently at the Alternate Site this summer. And while there are certainly concerns we’ll get to in a bit, Groome’s ceiling is still arguably as high as anyone in the system thanks to a potential for two plus pitches in his fastball and curveball to go with a solid changeup as well.
Weaknesses: Unfortunately, we haven’t been able to see that potential much at all, and a loss of development time is really the big weakness here. After being drafted in 2016, he has made only 20 starts as a professional and has made all of 11 as high as Greenville. And so now he is stuck in this weird place where he shouldn’t be rushed as the potential is too great, but also he is burning options on the 40-man. But for right now, he’s still only 22 and won’t turn 23 until the end of the 2021 minor-league system. He just needs to prove he can get through a season healthy, and we’ll worry about the rest once we cross that bridge.
Path to the majors: As I said, Groome is in a bit of a weird spot given his experience level. Sox Prospects has him projected for Salem, which makes sense, and I’d guess the hope is they’d be able to get him up to Portland for at least the last month or so of the season. They won’t rush him, but if things go well that’ll be ideal. The best-case scenario is likely a late-2022 debut, though 2023 is probably more likely.
