The Braves drafted Durbin in the 14th round of the 2021 MLB Draft, and he’s since been traded three times: to the Yankees, Brewers, and now the Red Sox.
Durbin, who turns 26 this month, is a versatile player with experience all over the infield. He played second and third base with Milwaukee this season.
Here are four things to know about one of the Sox’ newest additions.
He propelled WashU to the D3 College World Series
Durbin, who hails from the Chicago suburbs, didn’t get much attention from Division 1 programs during the recruiting process in high school. When Division 3 Washington University in St. Louis came calling, he didn’t even pick up the phone at first.
Get Starting Point

“I didn’t even know what WashU was,” Durbin told the WashU student newspaper, Student Life, in 2024. “I called [assistant coach Adam Rosen] back, and the first thing he said was, ‘Yeah, if you want to play here, you’re going to have to get your ACT score up to a 32.’ ”
He met that benchmark and went on to star for the Bears from the outset, starting all 41 games at shortstop his first year. In 93 games across three seasons (including the COVID-shortened 2020 season), Durbin recorded as many home runs (10) as he did strikeouts.
He propelled the Bears to the program’s first appearance in the College World Series as a junior in 2021, slashing .385/.460/.640.
The Bears made it all the way to the Final Four, where they fell to St. Thomas.
“We competed our butts off. That’s all you can really do,” Durbin said at the time.
Durbin went to Rookie ball after the Braves drafted him him in the 14th round, and he finished his WashU degree online the following year while playing with Single A Augusta.
He finished third in NL rookie of the year voting in 2025
After spending nearly three years in the Braves’ and Yankees’ minor league systems, Durbin made his Major League debut with the Brewers on April 18, going 2 for 4 with a run.
Dubbed “The Durbinator,” he hit his first Major League home run three days later and hit a walkoff bomb to beat the Padres on June 7.
Durbin provided about league-average offense in his rookie season, hitting .256 with a .334 on-base percentage and .387 slugging percentage.
He hit 11 home runs in 136 games with the Brewers and stole 18 bases in 24 attempts.
For his efforts, Durbin finished third in NL Rookie of the Year voting behind the Braves’ Drake Baldwin and the Cubs’ Cade Horton.
“[The Red Sox] really like a lot of what Caleb brings to the table,” chief baseball officer Craig Breslow said. “He showed last year that he can be a very good everyday player in the big leagues. He does a lot of things really, really well. When you think about some of the deficiencies that our team had last year in terms of putting the ball in play, not expanding the strike zone, catching up to fastballs — those are all things that he excels at.”
He was a prize wrestler in high school
Durbin comes from a family of wrestlers.
His father, Regis, and his older brother, Regis Jr., both wrestled at Northwestern. Durbin followed in their footsteps through high school, earning four varsity letters at Lake Forest High School (Ill.) while setting five school records in the sport.
Durbin also played one season of varsity football, tallying 31 total tackles at cornerback in just seven games, and his high school newspaper named him its Male Athlete of the Year in 2018.
He considered continuing his wrestling career in college in addition to playing baseball but opted to focus on just one.
“You don’t get too many baseball-wrestler combos,“ he told WashU’s student publication, Student Life. “I was the only one in my high school, but I think it helps a lot. . . . But just the fact that I’ve wrestled for eight years really helps with the physical and mental process of getting ready for baseball.”
He batted .500 as a high school junior
Durbin batted a staggering .500 during his junior season in high school.
The following year, he went hitless through his first 17 at-bats but brought his average back up to .350 by the end of the season and finished his high school career as the school record holder in hits (121), stolen bases (72), triples (12), and runs (111).
