MLB Rookie Power Rankings: Orioles, Yankees, Red Sox standouts emerge in AL ROY race

July was a breakout month for a plethora of rookie hitters who've finally started to find their groove at the plate. 

Was their surge enough to shake up the rookie top 10, or were their slow starts still too much to overcome? 

Below are the latest rookie power rankings, which feature two players making a return to the list and another cracking the top 10 for the first time this year. 

(Note: The rankings below will be updated once a month throughout the season. Also, while some outlets have Lawrence Butler , Xavier Edwards and Matt Waldron listed as rookies, they are no longer rookie eligible by MLB standards.) 

Who's surging? (honorable mentions)

Colt Keith (2B, Detroit Tigers ) 
Austin Wells (C, New York Yankees ) 
Jackson Chourio (OF, Milwaukee Brewers ) 

All three of these hitters have turned their rookie seasons around. Keith is the reigning American League Rookie of the Month after slugging .644 in July, though he is still hitting slightly below league average on the year. An expert framer and a patient at-bat, Wells now ranks in the top nine among rookie position players in both bWAR and fWAR. Chourio has multiple hits in nine of his past 13 games and an .872 OPS since the start of June, though the multi-talented 20-year-old is still hitting league average for the season. All three have an argument to make the list, though their slow starts at the plate can't be completely ignored just yet. 

Bumped out of top 10

Gavin Stone (SP, Los Angeles Dodgers ) 
Joey Ortiz (3B, Milwaukee Brewers) 
Bryan Hudson (LHP, Milwaukee Brewers)
