The St. Louis Cardinals had high hopes for prospect Alex Reyes in 2017. Those hopes are entirely gone, because an MRI showed that Reyes will need Tommy John surgery, and will miss the entire 2017 season. Reyes is ranked as the league's 14th best prospect overall, and 3rd pitching prospect by MLB pipeline. "Hopefully he'll be back better than ever. It's obviously very disappointing," Cardinals GM John Mozeliak said. "[We] had high expectations for him. But I guess if you're going to look at it from a timing standpoint, now he has a year to do his rehab and get everything he's dealing with under control." Reyes, 22, showed lots of promise in his first stint in the MLB, with an ERA of 1.57, a WHIP of 1.21, and 52 Ks in just 46 innings last season. It's a little of a surprise that Reyes dominated in the MLB last year, because in 2016, Reyes also made his AAA debut, with a putrid 4.96 ERA and 1.45 WHIP with 93 Ks (which is REALLY good) in just 65.1 innings, but the Ks did point out a positive spot with Memphis (AAA).
Reyes was supposed to be in the starting rotation in 2017, joining with SPs Carlos Martinez, Adam Wainwright, Michael Wacha and Mike Leake. The injury opens up a spot for Lance Lynn, who is recovering from Tommy John himself. Lynn was very good last time he played in the majors (2015). He had an ERA of 3.03, won 12 games, and struck out 167 batters in 175.1 innings that year. Prospect Luke Weaver, struggled late last season (it was his first stint in the majors) with an ERA of 5.70. He struck out 45 in just 36.1 innings in the majors. We'll need to wait and see if the Cards can still have a solid 2017 campaign, and if Reyes can return to his form in 2018.
