  Once Campbell was promoted to Double-A, he somehow took his game to another level as his mechanics became more routine. He raked to the tune of .362/.463/.582/1.045 with 8 homers, 17 doubles, and 3 triples for a 194 wRC+. It led to him bringing home Eastern League Player of the Week twice and earning a promotion to Triple-A after only 56 games, which was basically half the amount of time Mayer, Anthony, and Teel spent there.

  Arguably the most impressive part of Campbell’s recent stretch at Double-A was he stopped piling up strikeouts. His K% dropped to a measly 14.9% and his BB% was still strong at 13.7%. It’s rare to see a guy unlock significantly more power without any long-term drawback, but he seems to have cracked the code.

  On the defensive side of things, Campbell has had his hands full as well. He was introduced to center field entering 2024, so there’s been an obvious learning-curve on that end. Most of his time has been spent between there and second base, but he’s also appeared at shortstop and third base, so his profile carries plenty of versatility.

  Ultimately, the expectation is that Campbell will end up at second base or a corner outfield spot, but that’s a problem the Red Sox can figure out later. His ability to do damage from the right side of the plate makes him stand out when compared to Mayer, Anthony, and Teel. If he can keep tapping into that pull power, he could be a 20+ homer bat while playing half of his games at Fenway Park.

  Campbell isn’t some slouch from an athleticism standpoint either. While he may never be an above-average defender, he has plus speed that’s allowed him to steal 20 bags in 26 attempts between both levels. That would play with how the Red Sox have been operating on the basepaths this season.

  Following all the major publications updating their Top 100 prospects list at the mid-season mark, Campbell has started to get his proper due on a national scale. Baseball America has him at #98, MLB Pipeline at #79, Kiley McDaniel (ESPN) at #54, and Keith Law at #46. SoxProspects.com currently has him ranked as the #5 prospect in the system, with Braden Montgomery being the only thing separating him from Mayer, Anthony, and Teel at the top.

  There have been some critiques of Campbell’s swing, which is a bit unorthodox. It’s drawn comparisons to Hunter Pence and Lourdes Gurriel Jr. from various outlets, but neither is a perfect match. The important thing is he’s continued to handle velocity well, which was a concern when he was drafted and again with his new mechanics at the plate.

  It was fascinating to see some scouts in the Eastern League recently tell Peter Abraham of the Boston Globe that they believed Campbell was the best prospect in the system. To be fair, Campbell’s slash line at Double-A outperformed the trio, but he’s also older than both Mayer and Anthony. Teel is only a couple of months older than Campbell, but he plays a premium position with Campbell’s defensive home up in the air.

  Just going down the list, it seems like every corner of the baseball world is acknowledging Campbell as one of the more intriguing talents in the minors. Prospect evaluators in the media, scouts in front offices, and even his own teammates can’t help but rave about his ability. That should make it clear to everyone that the Big 3 has been put to rest and it’s officially the Fantastic Four.

  It’s rare to have so many impact position players on the verge of starting their big league career, but it only points to how bright of a future the Red Sox have right now, even if things have started to crumble during the playoff push. Considering how fast Campbell has moved through the minors, it can’t be ruled out that he’ll beat Mayer, Anthony, and Teel to the majors. Either way, no matter how the timeline plays out, it’s refreshing to see a major prospect breakout for the Red Sox farm system in back to back years.

  With Campbell in the mix, there’s no reason why the Red Sox shouldn’t have one of the most talented young cores in the sport for the rest of this decade. If that doesn’t come to fruition, he could serve as a key piece in a deal that brings over an ace or a middle of the order bat from the right side. I’ll leave that up to Craig Breslow, who’s going to have a lot of tough decisions to make this winter as he tries to construct the next World Series contender in Boston.
