2025 MLB rookie power rankings 2.0: Who takes the top spot one month in?

Our preseason Major League Baseball rookie power rankings were based primarily on the players we expected to make an immediate impact. 

Now, after more than a month of action on the field, the top 10 list looks a lot different. 

Kristian Campbell and Jacob Wilson have emerged as the top rookies on the diamond, but the rest of the players on the list below may come as more of a surprise.  

Of course, plenty of time remains for some of MLB's top prospects to either get the call or find their rhythm. For now, though, here are the latest FOX Sports rookie power rankings. 

(Note: The rankings below will be updated once a month throughout the season.)

Honorable mentions

It’s not often we’re discussing a 35-year-old rookie, but Sugano is building a strong argument for a spot on this list. His 3.00 ERA is tied for second among rookies who’ve made at least five starts and stands out in the Orioles’ dismal rotation, but the underlying numbers — a 5.11 FIP, 5.45 expected ERA, .297 expected batting average against and an overall inability to miss bats — suggest regression ahead. 

Ramírez already has 11 extra-base hits in just 53 at-bats, leading all rookies with a .963 OPS. He has only played in 14 big-league games, which is why he hasn’t quite cracked the top 10 yet, but he’ll find his way on it in short order if he keeps this up.

 Gusto, an 11th-round pick in 2019, is emerging as a valuable swingman in Houston. Opponents are hitting just .151 with 15 strikeouts against his four-seamer. 

The top 10

10. AJ Smith-Shawver , SP, Atlanta Braves

We’re early enough into the season that eight innings of one-hit ball on Monday, which dropped Smith-Shawver’s ERA down to 3.00, warrants the final spot on the list.

9. Justin
