More Baseball Rookies Than Ever — Their Careers Not Lasting As Long

There are many more baseball rookies being used by MLB teams these days. Statistics show that is not necessarily a good thing.

Rookies in 2025 combined to bat just under .230. Pitchers combined for an overall 4.82 ERA. That means more than half these players did not match these poor numbers and are likely destined for very short MLB careers.

Nick Kurtz and Jacob Wilson of the Athletics, Daylen Lile of the Washington Nationals, Agustin Ramirez of the Miami Marlins and Eric Wagaman of the Tampa Bay Rays had the best offensive output of all MLB players in 2025 who had rookie status.

Cade Horton of the Chicago Cubs, Jack Leiter of the Texas Rangers and the St. Louis Cardinals’ Matt Svanson and Michael McGreevy were the best pitchers among rookies.

How they eventually compare with rookies from 1925, 1955 and 2005 will not be known for another 20 years. We do know what rookies in those years accomplished over their careers, however. And it shows what everybody thinks of the game: there’s more home runs at the expense of fewer walks, more strikeouts, lower batting averages and poorer pitching.

Here are the average numbers for all players with rookie status in 2025, followed by what is right now, the career leader. After that, we have the same numbers for all rookies in 1925, 1955 and 1975.

One reason there’s more rookies now than 100 years ago is there are 30 MLB teams compared to 16 back then. That’s the biggest diffrerence, the dilution of talent, which also has taken a hit from the popularity of other sports. Yes, population has risen, but athletes are now turning to football, basketball, soccer, hockey and other sports. Baseball does not enjoy the exclusivity it once had.

Rookies In 2005

There are no players who were rookies in 2005 who have been elected to the Baseball Hall of Fame. There were many good players that had long and productive careers, however. Second baseman Robinson Cano, catcher Brian McCann and pitcher Felix Hernandez went to 8, 7, and 6 All-Star games respectively. First baseman Edwin Encarnación crashed 424 career homers. Huston Street had 324 saves.

But for every really good player there were boatloads of guys who lasted fewer than 20 games. Batting averages were lower, strikeouts increased and the game was not as entertaining.

Triples are exciting. The hitter is racing around the bases as fielders scramble to get the ball. Rookies in 1925 averaged more than 21 triples for a career. The 2005 rooks averaged 4.4.

Where Are Baseball Rookies Headed?

Baseball rookies will go in the direction that the game’s decision makers take the sport. Rules changes in recent years have tried to instill more contact hitting and base stealing.

It helped as evidenced by some top young rookies in 2025 such as Chandler Simpson, Jasson Dominguez, Jake Mangum and Caleb Durbin making an impression on the base paths.

All pitchers in Major League Baseball in 2025 with threw more breaking balls and off-speed stuff. If that trend continues, hurlers in the future should be able to carry more of a workload and have longer careers — as they did years ago.

In order to do that, pitchers usually must spend more time in the minors honing their craft. It takes a lot more time and instruction to master a four-pitch mix than just raring back and firing 100 miles per hour.

It won’t happen overnight but the recent trend is encouraging
