Every new MLB season brings surprises, and 2025 is shaping up to be no different. Some players bounce back from injuries, others refine their approach, and a few simply benefit from better luck. But who’s expected to improve the most this year?
To find out, we looked at players who had at least 450 plate appearances or 75 innings pitched in 2024 and compared their WAR (Wins Above Replacement) from last season to their projected WAR for 2025, using FanGraphs Depth Charts. Let’s break down the names expected to take the biggest leaps forward.
Michael Harris II Poised for a Breakout Year
Michael Harris II has already shown flashes of brilliance. After winning the National League Rookie of the Year in 2022 and following it up with a strong 2023 campaign, last season didn’t go quite as planned. He played only 110 games due to a left hamstring strain and posted a 99 wRC+ (Weighted Runs Created Plus), which was slightly below league average.
But 2025? The projections are bullish. FanGraphs expects him to post career highs across the board:
- 24 home runs
- 82 RBIs
- 90 runs scored
- 5.0 WAR (up from 2.0 in 2024)
If he stays healthy, Harris could return to being one of the best center fielders in baseball.
Christopher Morel Looks to Turn the Page
Christopher Morel’s 2024 season was one to forget. Despite showing promise in 2022-23 with solid offensive numbers, last year saw his production plummet. His wRC+ dropped to 82, and his defensive struggles contributed to a -1.0 WAR.
But was it just bad luck? A closer look suggests so. His .233 BABIP (Batting Average on Balls in Play) was far below expectations, and his expected wOBA (.316) was significantly higher than his actual wOBA (.280). The numbers indicate that Morel was hitting the ball better than his results showed.
That’s why FanGraphs is optimistic, projecting a rebound:
- 112 wRC+
- 1.4 WAR (a jump of +2.4 from 2024)
A fresh start in Tampa Bay could be just what he needs.
A Few More Names to Watch
While Harris and Morel stand out, other players are also expected to take big steps forward in 2025. Here are a few worth keeping an eye on:
| Player | 2024 WAR | Projected 2025 WAR | WAR Increase |
|---|---|---|---|
| CJ Abrams, SS, Nationals | 1.5 | 4.0 | +2.5 |
| Spencer Torkelson, 1B, Tigers | 0.8 | 3.0 | +2.2 |
| MacKenzie Gore, SP, Nationals | 1.2 | 3.5 | +2.3 |
CJ Abrams continues to refine his game, and with his elite speed and improving power, he could be on the verge of stardom. Meanwhile, Torkelson’s power potential remains sky-high, and Gore’s electric arm gives him ace potential if he can stay consistent.
What’s Behind the Improvement?
There are several reasons why these players are expected to make big leaps:
- Health: Injuries held back players like Harris last year. A full season of playing time naturally leads to better numbers.
- Luck: Morel’s expected stats suggest he was better than his results showed. If his luck evens out, he could be much improved.
- Development: Young players often take big steps forward as they adjust to the league. Abrams and Torkelson are prime examples.
The 2025 season is filled with potential comeback stories. While nothing is guaranteed, the numbers suggest these players could be in for major turnarounds. Baseball fans should keep an eye on them—big things could be coming.
