Some of baseball’s top minor league experts rank 11 St. Louis Cardinals prospects by tools and position vs. their competitors across MLB.

Some of baseball’s preeminent minor league experts from BaseballHQ share their rankings of 11 St. Louis Cardinals prospects on several tools-related “best of” lists. Plus bonus 2016 draft recap.

BaseballHQ’s annual “Minor League Baseball Analyst” arrived in my mailbox recently. The first prospect guide to fully integrate sabermetrics and scouting includes detailed reports on over 1000 minor leaguers.

In Part 1, we reviewed their top 15 St. Louis Cardinals prospects with the details as to why they’re ranked where they are. In Part 2, Cardinals’ organizational rankings in areas such as pitching, hitting, depth and top talent were compared to their National League Central Division competitors. Then we followed with a look at individual player movement and projections changes from 2016 to 2017.

Here in the final installment of this annual series, we will compare several of the top Cardinals prospects to the best in the game overall, by position in terms of long-range potential in the Major Leagues as well as in top skills. Closing this article will be a review of the Cardinals’ 2016 draft.

The Cardinals made a representative showing compared to other organizations with three players placing among the overall top 100 prospects. “Fair share” for any organization would also be three, though St. Louis’ had just one last year, down from three in 2015.


Top 100 Prospects of 2017 - Top 100 minor league prospects in terms of long-range potential in the major leagues. Their placement in the Cardinals top 15 follows.

1. Alex Reyes, RHP, STL (1)

78. Luke Weaver, RHP, STL (3)

95. Harrison Bader, OF, STL (6)

As in the case of many prospect raters, the overall site rankings represent a melding of multiple votes. BaseballHQ is no different. Shortstop Delvin Perez (ranked second in the system, as well as fourth and fifth-ranked Cardinals Jack Flaherty and Magneuris Sierra, missed the combined cut for the national rankings.

In the positional lists below, the Cardinals fared better than last year, when Sierra was the only hitter to place, among the top 45 outfielders. Sierra is joined by Bader among the top outfielders this year. Carson Kelly and Perez are near the end of the catching and shortstop lists, respectively. It is unclear if Randy Arozarena would have cracked the outfield list had he been placed there instead of second base.

The Cardinals still have a strong representation - three names - on the top 75 starting pitching list, but it is down from five in 2016. That can serve as a reminder that trading strength in one area to address needs in another is an approach that may continue. No Cardinals replaced Sam Tuivailala, who dropped the top 15 relief prospects list.

The Cardinals found themselves in the familiar position of having to wait until the back-end of round one, but were able to land top 10 talent in Puerto Rican SS Delvin Perez. Perez fell in the draft due to a failed drug test (PED), but was one of the better athletes in the draft, showing plus speed, a strong arm, and the chops to stick at short. Perez had a nice debut, hitting .294/.352/.393 in the GCL. The Cardinals then added prep OF Dylan Carlson (1), Mississippi State RHP Dakota Hudson (1), Virginia RHP Connor Jones (2), North Carolina RHP Zac Gallen (3), and USC C Jeremy Martinez. Martinez slashed .325/.419/.433 with 32 BB/16 K in 194 AB. Another impressive haul for the savvy Cardinals.

Sleeper: Vincent Jackson OF (14) is a tall, athletic OF who played college ball at Tennessee. He struggled during his junior year due to a thumb injury, but had a solid senior season, hitting .333/.426/.507 playing along Nick Senzel.

Grade: A (up from B in 2016)


Other NL Central Draft grades

Cincinnati: A

Milwaukee: A-

Pittsburgh: B-

Cubs: D
