Alcantara has one pitch right now, but it is a very lively pitch. His fastball touches 100 and it is overpowering when batter aren't sitting on it. The problem is his other pitches are nowhere near the quality of the fastball, and their inconsistency coupled with his spotty control led to the results we saw in 2018. We know his secondary pitches are lagging behind his fastball when we see a strikeout rate that belies the velocity he brings from the mound. He is also barely over 23 years old and has 42 more innings of work at the major-league level than 98% of 23-year-olds in organized baseball. This is the kind of pitcher you want to keep at arm's length in reset leagues in 2019 but need to get on board with in keeper and dynasty leagues and ride out the bumps as his stuff comes together.

Dealt to the Marlins as one of the two headliners (along with Magneuris Sierra) for Marcell Ozuna, Alcantara has an arm that's easy to dream on. He has an athletic 6-foot-4 frame, can reach back for 101 mph on his fastball when needed, and won't turn 23 until September. His warts are fairly obvious -- his two breaking balls are very inconsistent and his command/control has a long way to go before he comfortably projects as a long-term starter. However, the trade to Miami will give him a legitimate chance to fix those issues over the next couple years, as he would have likely been fast-tracked to the big-league bullpen had he remained with the Cardinals. Alcantara's changeup projects as a plus pitch, so there is more to work with here than just elite fastball velocity. At worst, he will be a high-strikeout setup man in the Dellin Betances mold. If one of his breaking balls emerges as a legitimate weapon and he improves his command, he could still end up as a No. 1 or No. 2 starter.

Every couple years the Cardinals seem to have an uber-projectable righty turning heads in the lower levels of their system. Sometimes that pitcher turns into Tyrell Jenkins, and sometimes that pitcher develops into Alex Reyes. Alcantara seems to have more in common with Reyes, as he boasts a similar 80-grade fastball that touches triple digits and can sit comfortably around 96 mph. He has a long way to go before he projects to pitch atop a rotation, however, as the command and secondary offerings leave a lot to be desired. His 6-foot-4, 170-pound frame has room to comfortably add mass without sacrificing the electricity that makes him special, and the hope is that this would lead to improved command. Alcantara's changeup is his best secondary offering, already serving as an average pitch. If his curveball can develop into an out pitch in the coming years, then the rest of the ingredients are here for a monster pitcher. This frontline upside is what separates him from some of the more polished arms in the Cardinals' organization.

Alcantara remained at the rookie level for his second professional season, this time pitching stateside after spending 2014 in the Dominican Summer League, and the results were generally strong in 12 starts for the Gulf Coast League Cardinals. While the strikeouts were down from the previous season, with his K/9 falling from 8.7 to 7.1, he also cut down on the walks and was once again able to limit the longball. In fact, in 121 innings so far as a professional (514 batters faced), Alcantara has surrendered just four home runs thanks to a 1.90 GB/FB. He has a long, slender frame at 6-foot-4, 170 pounds, which is the kind of build many scouts like for a future MLB starter, but it would be nice to see the 20-year-old fill out a bit in the coming years to ease durability concerns. Alcantara figures to receive his first full-season assignment in 2016.
