When the Minnesota Lynx visit the Los Angeles Sparks on Tuesday, it will be just another regular-season game for two teams with championship aspirations.

For the WNBA, it will be so much bigger.

The defending champion Lynx are 12-0 and the Sparks are 11-0, marking the the first time that two unbeaten teams from the WNBA, NBA, NFL, MLB, or NHL have met with each team having at least 10 wins with no losses and no ties.

For a league eager to gain traction in its 20th season, compelling matchups like this one that include a little history in the making are just what’s needed.

“A championship is not going to be won or lost with this game,” Lynx star Maya Moore said Monday. “But at the same time, how great a scenario for two competitive teams to go out and play and really make a statement with their performances.”

The timing couldn’t be better, with the NBA Finals having just concluded in dramatic fashion on Sunday. The NFL is on hiatus for the next five weeks until training camps open and the U.S. Open also wrapped up on Sunday.

So the door is open for the women.

“It’s amazing that two teams are playing so well and have had historical starts in the 20th season,” Sparks forward Nneka Ogwumike said. “It’s a very important milestone for the WNBA.

“I think it’s also an honor and I’m proud to be a reflection of this league’s growth,” she said. “A lot of people still wonder where the league is going and I think it’s still going up and progressing. It’s important to know we’ve come a long from where it’s begun.”

The starts for the Lynx and Sparks are crucial in a season that will test players even more because of the Olympics in August. Both teams insist they haven’t been scoreboard watching, even as they have been unable to pull away from the other as the wins have piled up.

Under second-year coach Brian Agler, the Sparks have made enormous improvement defensively to better balance a team that is loaded on offense with Candace Parker, Ogwumike and Kristi Tolliver.

The Lynx have spent the season incorporating some new faces to a star-studded core that has won three titles in the last five seasons and is looking to become the league’s first repeat champion since 2002.

The last team to do it? The Sparks.

The league will unveil its list of the 20 greatest players in WNBA history on Tuesday as it continues to celebrate its 20th anniversary.

It hasn’t always been easy for the league to carve out a place for itself in the sporting landscape, but Lynx coach Cheryl Reeve said she is encouraged by what she’s seen under new leadership and a double-down of support from NBA Commissioner Adam Silver.

“When the decision-makers get behind their words when it comes to advocating for women, you see real results,” Reeve said. “I’m excited that Adam has put that out there and I’m excited to see him follow through on his words.”
