When Caitlin Clark entered the WNBA, few doubted her offensive firepower. But for all her accolades, she still had something to prove—especially against the league’s most established stars. One of those stars? Brittney Griner, the 6-foot-9 former No. 1 pick, 10-time All-Star, and towering face of post dominance in women’s basketball.

Griner’s career has been one of resilience and legacy. A national champion at Baylor, an Olympic gold medalist, and a fixture on All-WNBA lists, she remains one of the league’s most respected veterans. When Caitlin Clark began generating historic viewership and media attention during her collegiate years, Griner issued a subtle but firm reminder of what awaited her in the pros:

“It’s different when you come from college to the pros. I went from Top Dog to facing grown women feeding their families. This isn’t just a game—it’s a livelihood.”

It was less a warning than it was a rite of passage. Everyone entering the league must earn their place—not through hype, but through performance.

June 30th. Phoenix. Fever vs. Mercury. The date marked the first-ever head-to-head clash between Caitlin Clark and Brittney Griner. Two former No. 1 picks. Two faces of different eras. One arena.

The matchup didn’t disappoint. Over 17,000 fans packed the building to witness the showdown—proof that Clark’s drawing power is very real. Yet what unfolded wasn’t just a duel of size versus speed, or rookie versus veteran. It became a referendum on the question: Can skill and vision overcome size and strength?

Phoenix struck early. Griner established herself in the paint, scoring on fadeaways and cleaning up at the line. Diana Taurasi fed her the ball with clockwork precision. Indiana, meanwhile, looked out of rhythm. Caitlin Clark, used to explosive starts, was bottled up early, and Griner’s physical presence was a constant deterrent.

Then, something shifted.

Midway through the first quarter, Clark drilled a deep three—her signature. It didn’t just cut into the lead. It changed the energy in the building.

Griner wasn’t backing down. She went on to score 24 points that night and remained dominant in the paint, but her frustration showed. A scuffle with Fever center Aaliyah Boston resulted in a technical foul. Boston, just in her second year, refused to be bullied. It was a clear message: Indiana wasn’t going to be pushed around.

Clark responded the only way she knows how—with playmaking. Her shooting wasn’t vintage, but her passing was surgical. She finished with 15 points, 9 rebounds, and an astonishing 12 assists, leading Indiana to an 88–82 win. Notably, Aaliyah Boston led all Fever scorers with 17 points—many of them directly created by Clark’s vision.

Despite being outscored by Griner, Clark dictated the game’s tempo. She turned defensive attention into offensive advantage. At times, Phoenix’s defenders were so locked onto her that they allowed wide-open cuts, including a critical score by Christy Wallace, created solely by the gravitational pull Clark commands.

After the game, Taurasi offered high praise: “What she’s doing—it’s not normal. She’s changing the game.”

But it wouldn’t be their only battle.

July 12th. Indiana. The rematch. This time, Clark wasted no time. She hit a step-back three over Griner early in the first quarter, then slashed to the rim for a layup through traffic. It was the kind of start that silenced doubters. Clark wasn’t here to survive. She was here to own the moment.

Griner responded with vintage footwork and post-up buckets, showing the Fever crowd she still had plenty in the tank. On defense, she sent a message with a towering block on Boston.

But Clark? Unfazed.

She resumed her role as floor general. A pass through a crowded lane to a cutting Boston. A whip-around assist to Kelsey Mitchell for three. The stat sheet exploded: Clark would finish the night with 20 points and 13 assists, marking her second straight game with double-digit dimes against the Mercury.

It would also mark Indiana’s second straight win over Phoenix, 95–86.

Clark didn’t need to drop 30 to make her mark. She bent defenses in every direction, often without touching the ball. On several plays, Phoenix defenders refused to leave her, even when the ball was nowhere near her—allowing teammates like Boston and Mitchell to feast on mismatches.

Late in the third, Clark danced past her defender with a slick between-the-legs crossover, gliding to the rim for two. By that point, the Mercury were reeling, and Griner, who had already shown signs of discomfort, exited after a collision with a teammate.

From there, Clark continued to dismantle Phoenix’s defense—methodically, patiently, and with veteran poise. She controlled the fourth quarter without scoring a single point. The Fever’s system hummed through her fingertips.

Griner didn’t speak much postgame. She acknowledged Clark’s draw and the frenzy that surrounds her every move.

“I can only imagine what it’s like for her. She probably can’t even go to the grocery store,” Griner said. “I’ve been there—it’s a lot.”

Clark, in return, offered grace and gratitude.

“She’s a staple of this league,” Clark said of Griner. “To hear that from her… it means something.”

Two players. Two timelines. One respect.

While Clark’s shooting wasn’t perfect—she shot 4-of-14 in the first game and 8-of-16 in the second—her impact on the court was undeniable. It was never just about the buckets. It was about how she orchestrated the entire game.

She controlled tempo. She created space. She elevated everyone around her.

These two showdowns against Griner proved something that numbers alone can’t measure: Caitlin Clark doesn’t need size to dominate. She’s rewriting the rules through skill, IQ, and relentless composure.

And if these two games are a sign of what’s to come, the WNBA isn’t just witnessing a rivalry. It’s witnessing a changing of the guard.
