Red Sox infield prospect Anderson setting a definite 'Tone' in the desert

SCOTTSDALE, Ariz. -- Every autumn, the Arizona Fall League gives prospects who don’t appear on their respective clubs’ Top 30 lists a chance to really pop. Through the first two weeks of action, Antonio Anderson is the leader in the clubhouse for taking that invitation to show what he can do on a bigger stage and running with it. 

“I just play my game,” the Red Sox third-base prospect said. 

Playing his game has given Anderson a .333/.517/.667 slash line through his first six games, earning him a spot among the Fall League’s top performers from Week 1. He demolished a pair of home runs, including a 115.2 mph go-ahead grand slam for Mesa on Oct. 9. It stands as the second-hardest-hit ball on the circuit through play Thursday.

“The feeling is surreal,” Anderson said. “To be completely honest with you, the 115 [mph homer], I actually didn't get all of it. I swung and it was just maybe 75-80 percent. I think I got a 121, 122 [mph exit velocity] in the tank. 

“I don't really swing it too hard. I just try to put the bat on the ball because the pitcher brings the velo.”

“'Tone' has been awesome to watch,” said Mesa hitting coach Jacob Caples, a member of the Blue Jays organization. “Some of the home runs that he's hit and gotten to -- I mean, he said in the dugout after his home run the other day, ‘Man, that was a [personal record.]’ To have one of his best swings of the year come from here, that’s really cool.” 

There have been a lot of good swings in 2026 for Anderson, who enjoyed a breakout season with High-A Greenville. After posting a combined .609 OPS across his first three years in the system, the switch-hitting corner infielder put up an .826 mark while setting career highs in a bevy of categories, including homers (nine), RBIs (46) and total bases (131). 

To hear him tell it, the answer is quite simple really -- literally. 

“Just having more of a simple swing, not doing too much with my hands and lower half -- straight back, straight to the ball,” Anderson said. “The main thing was just pitch selection -- like those balls that weren't really my pitch, lay off those. And then the ones that were part of the zone, get on those.”

The under-the-hood data indicates Anderson did just that. His walk rate jumped over 3 percent from 2025, settling in at 12.7. While his strikeout rate is still slightly elevated (23 percent), it was far and away a career best, as was the percentage of pitches that went against him as a called strike or whiff (26.8). 

While Anderson will need continue to hone his swing in order to tap into his natural raw pop more after running a 48.1 ground-ball rate, he ranked 10th among all Red Sox Minor Leaguers with at least 300 plate appearances with a 24.8 percent line-drive rate. With more than 35 percent of his balls in play going to the opposite field, he ranked tops in the system under the same guidelines, a testament to his all-fields approach. 

The Red Sox nabbed Anderson in the third round of the 2023 Draft and handed the Atlanta prep standout a well-over-slot $1.5 million signing bonus to forgo his commitment to Georgia Tech, where he could have starred alongside ‘26 first-round picks and current Top 100 prospects Vahn Lackey (third overall, Twins) and Drew Burress (eighth overall, Athletics). 

Anderson has thought about what things could have been like if he went the college route -- “Imagine if I went there and used a metal bat?” – but feels like spending time developing in Boston’s system has set him up for success in the long run.

The organization recently developed another Georgia prep standout who did go on to star for Georgia Tech -- Kristian Campbell, who won MLB Pipeline’s Hitting Prospect of the Year Award in 2024. Campbell has been the poster child of the organization’s focus on improving bat speed, which helped him go from an unheralded prospect to The Show in short order. 

“The main thing was bat speed,” said Anderson of what the organization has hammered home. “I feel like [once] I had the swing decision [down], worked on putting the bat on the ball also. But bat speed we definitely unlocked.” 

To stand by the cage and see Anderson unleash that wallop from both sides of the dish is a sight to behold, even in a league full of top prospects. After watching him deposit consecutive pitches onto the right-field berm during batting practice, Caples laughed: 

“Look at Tones putting on a show. It’s just awesome to watch.”
