19 Baseball Prospects Who Were Supposed to Be the Next Big Thing

Every year, baseball fans hear about the next can’t-miss prospect—those phenoms who are supposedly destined to be future MVPs, Hall of Famers, or the face of a franchise. But for every Bryce Harper or Mike Trout, there are plenty of names that never quite lived up to the hype.

Sometimes it’s injuries, sometimes it’s the pressure, and sometimes the magic just never clicks at the major league level. These are the baseball prospects who were once touted as the future of the sport… but ended up as cautionary tales instead.

19. Matt Bush

Jun 30, 2023; Pittsburgh, Pennsylvania, USA; Milwaukee Brewers relief pitcher Matt Bush (21) pitches against the Pittsburgh Pirates during the ninth inning at PNC Park. Pittsburgh won 8-7.

A No. 1 overall pick with a big arm and an even bigger list of off-field issues. Bush’s career was derailed before it ever really got going.

18. Jesus Montero

Apr 28, 2012; Toronto, ON, Canada; Seattle Mariners designated hitter Jesus Montero (63) bats against the Toronto Blue Jays at the Rogers Centre. The Blue Jays beat the Mariners 7-0.

He was supposed to be the Yankees’ next great hitter, but it didn’t take long for that dream to crumble. A trade, some weight issues, and a very strange ice cream incident later, and Montero was off the radar.

17. Domonic Brown

Mar 2, 2016; Dunedin, FL, USA; Toronto Blue Jays outfielder Domonic Brown (81) bats in the third inning of the spring training game against the Philadelphia Phillies at Florida Auto Exchange Park.

At one point, he was MLB’s top-ranked prospect and the future of the Phillies’ outfield. A hot month in 2013 was as good as it ever got.

16. Tim Beckham

Jul 31, 2019; Arlington, TX, USA; Seattle Mariners left fielder Tim Beckham (1) singles in a run in the first inning against the Texas Rangers at Globe Life Park in Arlington.

Taken first overall ahead of Buster Posey, Tampa really thought they had their guy. They didn’t.

15. Mark Appel

Aug 2, 2022; Atlanta, Georgia, USA; Philadelphia Phillies relief pitcher Mark Appel (22) looks at a runner on first against the Atlanta Braves in the fifth inning at Truist Park.

Drafted first overall and out of baseball before ever throwing a major league pitch. He made a short-lived comeback, but the hype train had long since derailed.

14. Joba Chamberlain

May 21, 2016; Boston, MA, USA; Cleveland Indians relief pitcher Joba Chamberlain (62) pitches during the seventh inning against the Boston Red Sox at Fenway Park.

Joba-mania was real, and Yankees fans thought they had their next ace. Unfortunately, inconsistent roles and injuries ended that fantasy quickly.

13. Dustin Ackley

Aug 29, 2012; Minneapolis, MN, USA: Seattle Mariners second baseman Dustin Ackley (13) throws the ball to first base to get out Minnesota Twins center fielder Ben Revere (not pictured) in the first inning at Target Field.

The Mariners had high hopes when they drafted him second overall. Instead, they got a second baseman who never really figured out how to hit big-league pitching.

12. Brandon Wood

August 30, 2011; Houston, TX, USA; Pittsburgh Pirates infielder Brandon Wood (2) catches a line drive for an out in the sixth inning against the Houston Astros at Minute Maid Park.
Troy Taormina-Imagn Images

The hype around Brandon Wood was unreal, and for a minute, it looked like he might live up to it. But once he hit the majors, he just couldn’t figure out how to hit anything else.

11. Delmon Young

May 31, 2015; Baltimore, MD, USA; Baltimore Orioles right fielder Delmon Young (27) hits a solo home run in the first inning against the Tampa Bay Rays at Oriole Park at Camden Yards.
Tommy Gilligan-Imagn Images

The hype was loud and constant for the first overall pick. He had his moments, but they were never as great or as consistent as everyone hoped.

10. Sean Burroughs

Jun. 1, 2011; Phoenix, AZ, USA; Arizona Diamondbacks infielder Sean Burroughs against the Florida Marlins at Chase Field.
Mark J. Rebilas-Imagn Images

As the son of a big-leaguer, expectations were sky-high. But despite a sweet swing, the success never translated into the big leagues.

9. Alex Gordon (early career)

Mar 27, 2007; Mesa, AZ, USA; Kansas City Royals third baseman (7) Alex Gordon against the Chicago Cubs at Hohokam Park in Mesa, AZ.
Mark J. Rebilas-Imagn Images

He eventually turned things around, but Gordon’s early years were not what Royals fans signed up for. It took a position change and a few years of struggles before he finally lived up to some of the promise.

8. Fernando Martinez

April 26, 2013; Boston, MA USA; Houston Astros right fielder Fernando Martinez (21) bats during the eighth inning against the Boston Red Sox at Fenway Park.

The Mets thought they had something special. Instead, they got a guy who never put it all together, no matter how much patience they had.

7. Todd Van Poppel

He was supposed to be the next Nolan Ryan. He wasn’t even the next Rick Ankiel.

6. Bubba Starling

Sep 5, 2020; Kansas City, Missouri, USA; Kansas City Royals center fielder Bubba Starling (11) fields a fly ball in the fifth inning against theChicago White Sox at Kauffman Stadium.

The local Kansas kid who was supposed to be the savior of the Royals. But the bat never caught up to the glove, and the dream faded fast.

5. Clint Hurdle

Jun 23, 2007; Toronto, ON, Canada; Colorado Rockies manager (13) Clint Hurdle argues with home plate umpire and crew chief Gerry Davis after his catcher (8) Yorvit Torrealba (not pictured) was ejected in the 4th inning against the Toronto Blue Jays at the Rogers Centre in Toronto, ON. Toronto won 11-6.
Tom Szczerbowski-Imagn Images

Before he became a manager, Hurdle was hyped as “The Next Big Thing” on the cover of Sports Illustrated. He ended up being a much better skipper than slugger.

4. Phil Hughes

Oct 4, 2011; Detroit, MI, USA; New York Yankees starting pitcher Phil Hughes (65) pitches during game four of the 2011 ALDS against the Detroit Tigers at Comerica Park.
Rick Osentoski-Imagn Images

Yankees fans penciled him in as the next ace by the time he was 21. He had some solid years, but he never quite matched the insane expectations.

3. Andy Marte

Feb 26, 2014; Salt River Pima-Maricopa, AZ, USA; Arizona Diamondbacks third baseman Andy Marte (76) celebrates after defeating the Los Angeles Dodgers at Salt River Fields at Talking Stick. The Los Angeles Dodgers won the game 4-1.

Once a top prospect in all of baseball, Marte was traded twice based on potential alone. Sadly, that potential never really showed up on the field.

2. Billy Bean (not Moneyball Billy Beane)

Jun 16, 2023; Los Angeles, California, USA; The only openly gay Major League Baseball player, BIlly Bean, is acknowledged on Pride Night prior to the game between the Los Angeles Dodgers and the San Francisco Giants at Dodger Stadium.

Drafted high and given the spotlight early, Bean never found his footing in the majors. But hey, he ended up with a fascinating story—and a Netflix doc to boot.

Once the Dodgers’ most electric arm, Miller had ace written all over him. But after a series of arm injuries, the fireballer was gone before he even got started.
