26. Boston Red Sox: 1B/3B Triston Casas, American Heritage (Fla.) HS
Casas ranks right with Nolan Gorman as one of the best high school power hitters in this Draft. He had a chance to go as high as No. 13 to his hometown club in Miami, and a few other spots in the teens, so getting him at No. 26 is a nice grab for the Red Sox. While he has some athleticism for his size (6-foot-4, 240 pounds), Casas is most likely a first baseman, albeit one with a strong arm who can delivery 94 mph fastballs on the mound.

3B Triston Casas, American Heritage School (Florida). Casas is a third baseman presently, but it's highly likely he'll be shifted to first as a pro. He's got big power, but he's also got some issues making contact. Scouts are mixed on how well that power will translate, but the potential for big numbers is there. He's committed to Miami.

The Red Sox are on a quest to rebuild their farm system, and they’ve gotten started with their first pick of the 2018 MLB draft on Monday night. With that selection, they went with high school first baseman Triston Casas with their first round pick at number 26 overall. He is 18 years old and went to American Heritage High School in Florida. He is also committed to the University of Miami next year.
This bucks their recent trend of taking pitchers in the first round, something they’ve done in each of the last two years. It also goes against some of the recent mocks, though Casas was mentioned as a possibility by a few publications.
We’ll have a lot more on Casas later on tonight, but for now here are the basics. Although he’ll be listed as a 1B/3B, it’s almost certain that he will be a first base only player soon enough, and possibly as soon as this year. The bat has huge potential, though, particularly the power. There are some questions about the hit tool, but the Red Sox clearly believe it is good enough for him to tap into that raw power. Baseball America has him ranked as their number 25 prospect in the draft, while MLB Pipeline has him at 20 and Fangraphs has him at 33.
