Since the St. Louis Cardinals last played in the World Series (2013), the franchise has suited up six prospects of the “can’t miss” variety. These are the future stars who become centerpieces in annual postseason runs. Alas, the six players share two distinct similarities: each has played for the Memphis Redbirds, and each has, in fact, missed.
Oscar Taveras was the Cardinals’ Minor League Player of the Year with Double-A Springfield in 2012. By the time he suited up for Memphis in 2013, Taveras was the second-ranked prospect in all of baseball. A line-drive machine from the left side of the plate, Taveras battled injuries over two seasons with the Redbirds, but still hit .306 over 46 games in 2013 and .318 over 62 games before being promoted to St. Louis in 2014. He hit a game-tying home run in the only game St. Louis would win in the 2014 National League Championship Series, then died with his girlfriend in a car accident two weeks later. Taveras was intoxicated behind the wheel.
Michael Wacha needed only 15 games at the Triple-A level to convince the Cardinals he was ready for a big-league rotation. After posting a 2.65 ERA for Memphis in 2013, Wacha joined St. Louis and came within an out of no-hitting the Washington Nationals in only his ninth major-league start. He earned MVP honors in the 2013 NLCS, twice beating the Dodgers and not allowing a run in 13 innings. He battled injuries but remained a part of the Cardinals’ rotation for six years, winning 17 games in 2015. Since departing as a free agent after the 2019 season, Wacha has pitched for five different clubs. Now with the Kansas City Royals, he’s four wins shy of 100 for his career.
Alex Reyes was the Cardinals’ Minor League Pitcher of the Year in 2015 at the tender age of 21. He struck out 93 hitters in only 65 innings for Memphis in 2016 before a late-season promotion to St. Louis, where he posted a 1.57 ERA over 46 innings. But Reyes only pitched in 20 games over the next four years, sidelined by one significant arm injury after another. He made the National League All-Star team as a closer in 2021, a season he topped for the Cardinals with 29 saves. But he hasn’t thrown a pitch since surrendering a walk-off homer in a wild-card loss to the Dodgers to end that season.
Jack Flaherty was the Cardinals’ Minor League Pitcher of the Year in 2017 when he helped the Redbirds to a Pacific Coast League championship by going 7-2 with a 2.74 ERA over 15 starts. He was a certified big-league ace two years later, posting a 2.75 ERA and the most strikeouts (231) in a season for St. Louis since Hall of Famer Bob Gibson retired in 1975. But by 2023, Flaherty was a trade piece, going to Baltimore in return for current Redbirds infielder Cesar Prieto.
Dylan Carlson was the Cardinals’ Minor League Player of the Year in 2019 when he hit .361 over 18 games with Memphis after a September promotion from Springfield. He lost what would have been a full season at Memphis to the 2020 pandemic, but still took over right field in St. Louis in 2021. Carlson finished third in National League Rookie of the Year voting that season after hitting .266 with 18 home runs and 65 RBIs. But injuries have diminished his production. Carlson batted .198 over 59 games this season before the Cardinals traded him to Tampa Bay last week.
It’s unfair to include 22-year-old Jordan Walker among this group of fallen stars, but you can’t help but wonder (if not worry) with Walker posting pedestrian numbers (.252, 7 home runs through Sunday) against Triple-A pitching after leading the Cardinals with a .276 average a year ago. Prospects are fun to rank and track as they rapidly climb the minor-league ladder. But sustainable success in the big leagues remains the goal. And for a franchise now more than a decade removed from its last National League pennant, “can’t miss” must be reconsidered.
