Len Kasper Embraces White Sox Radio After Cubs TV Tenure

This blog post digs into Len Kasper’s landmark switch from the Cubs’ TV booth to the White Sox radio booth in 2020. It explores what drove him, that first postseason moment, the tough years that followed, and how his approach has shaped Sox broadcasts and even the team’s vibe.

It also takes a look at Kasper’s on-air philosophy. His style, rooted in a lifelong radio dream, has earned him a respected spot in Chicago baseball lore.

A bold leap: Kasper’s move from Cubs TV to White Sox radio

On December 4, 2020, Len Kasper surprised just about everyone by leaving a 16-year Cubs TV run to become the White Sox radio voice. He’s said the decision wasn’t about team loyalty—it was about a lifelong urge to work in radio, inspired by Tigers legend Ernie Harwell.

Kasper stepped into the role after Ed Farmer’s passing. He embraced the radio medium he’d admired since he was a kid, bringing a fresh spark to the Sox broadcast team.

Harwell’s influence and a radio-first mindset

Kasper often points to Harwell’s calm, steady cadence as his blueprint for keeping enthusiasm alive, no matter the score or situation. He tries to keep listeners engaged, using Harwell’s example to balance play-by-play details with some personality.

This radio-first approach let Kasper turn his passion into a professional home with the Sox. The microphone became his stage and, honestly, his calling card.

A season of breakthroughs and rebuilding challenges

In his first year with the South Siders, Kasper called postseason games—something he couldn’t always do with the Cubs. The White Sox won the AL Central in 2021, a sharp contrast to the Cubs’ slow unraveling after their 2016 championship.

The broadcast’s resilience through a brutal stretch

The next three seasons? Rough. The team lost over 100 games each year, ending with a brutal 121-loss season in 2024.

Kasper and analyst Darrin Jackson had to find ways to keep broadcasts interesting, even when the games weren’t. Kasper’s steady, Harwell-inspired style became a hallmark of Sox radio during this painful rebuild.

Relationships, rivalry, and a lasting Sox legacy

Despite the classic North Side vs. South Side rivalry, Kasper’s kept good relationships with Cubs folks, including his friend and Cubs analyst Jim Deshaies. Within the Sox organization, he’s become so much a part of things that his portrait hangs in the radio booth alongside other long-tenured broadcasters.

Kasper’s often said he feels right at home in this role. That sense of belonging goes back to a dream he’s chased since he was 12.

A symbol of belonging and a future-focused broadcaster

The Sox’ recognition of Kasper isn’t just for show. The team genuinely believes in his ability to carry the booth’s legacy forward, even as the game changes and analytics and storytelling share the spotlight.

As the White Sox try to claw back to competitiveness and reconnect with fans, Kasper’s voice remains steady and familiar. There’s something comforting about that, isn’t there?

Today and beyond: Kasper’s continuing impact

With the team showing signs of life and fans getting excited again, Kasper says he’s where he belongs. He’s the right voice for a White Sox era that’s still figuring itself out.

His career arc—built on childhood radio dreams and Harwell’s influence—offers a pretty compelling example for anyone chasing a broadcasting career that’s about craft, passion, and a little bit of stubbornness.

Key takeaways from Kasper’s journey

• Radio-first philosophy shapes how he approaches on-air decisions and pacing.
