MILWAUKEE (CBS 58) — The Milwaukee Brewers and Tampa Bay Rays are not the only ones with something on the line in the World Series.

From mayors and museums to hospital executives and Catholic leaders, Milwaukee and the Tampa Bay area have agreed to several friendly wagers as the Brewers and Rays each pursue the first World Series championship in franchise history.

Milwaukee Mayor Cavalier Johnson and St. Petersburg Mayor Ken Welch are taking part in what they are calling the "Mayor's Challenge."

If the Brewers win, Welch will ride around St. Petersburg on his Harley-Davidson motorcycle while wearing a Brewers jersey. If the Rays win, Johnson will wear Rays gear in Milwaukee and the Hoan Bridge will be lit in Tampa Bay's team colors.

"We're using a little friendly competition to make an even more positive impact in our communities," Johnson said. "We are rallying to give back to the community in each of our cities."

The challenge was announced on social media and quickly drew hundreds of interactions.

The friendly competition is also reaching the art world.

The Milwaukee Art Museum and Museum of Fine Arts, St. Petersburg, are putting works by Claude Monet on the line, with the losing city's museum agreeing to temporarily loan one of its paintings to the winning team's hometown.

If the Brewers win the World Series, Milwaukee will receive St. Petersburg's "Houses of Parliament: Effect of Fog, London," painted in 1904.

If the Rays win, the Milwaukee Art Museum will loan its "Waterloo Bridge, Sunlight Effect" to the Museum of Fine Arts in St. Petersburg.

Ownership of the paintings will remain with their respective museums. Loan and exhibition dates will be announced after the series.

"When I moved to Milwaukee, I became a part of the Brew Crew," Milwaukee Art Museum Director Kim Sajet said. "They're the best team in baseball, and I'm backing them with one of our most beloved paintings. Two Monets will look incredible in our galleries. Klaudio, consider this your invitation to visit Milwaukee. Go Brewers!"

Klaudio Rodriguez, executive director and CEO of the Museum of Fine Arts, St. Petersburg, responded with confidence in the Rays.

"We admire Kim's enthusiasm, but we think Milwaukee's Monet would enjoy a little Florida vacation," Rodriguez said. "We're backing the Rays all the way, and we're ready to welcome Milwaukee's masterpiece to St. Petersburg. Let's see Milwaukee put its Monet where its mouth is."

It is not the Milwaukee Art Museum's first championship wager.

In 2011, the museum and Pittsburgh's Carnegie Museum of Art wagered painting loans on the outcome of Super Bowl XLV between the Green Bay Packers and Pittsburgh Steelers.

Children's hospitals in the two World Series cities are also getting involved.

Children's Wisconsin President and CEO Gil Peri has challenged Alicia Schulhof, president and CEO of Johns Hopkins All Children's Hospital in St. Petersburg, to a friendly wager. Fans will vote on social media to determine what the losing CEO will have to do.

Children's Wisconsin is also showing its Brewers spirit throughout the series. The hospital's Child Life team held a Brewers pep rally Friday afternoon, where patients and families made Brewers artwork, played games and cheered on the team.

Kids at the rally also sprayed the hair of Dr. Dave Margolis blue and gold before he headed to Game 1.

The Children's Wisconsin hospital in Milwaukee is also being lit in Brewers blue and gold throughout the World Series.

The friendly competition is even extending to the Catholic Church.

Milwaukee Archbishop Jeffrey S. Grob and St. Petersburg Bishop Gregory Parkes have placed a wager of their own, with donations to Catholic Charities and local specialties at stake.

If the Brewers win, Parkes will make a donation to Catholic Charities of the Archdiocese of Milwaukee and send a box of hand-rolled cigars from the Tampa Bay area.

If the Rays win, Grob will send brats from Bunzel's Meat Market to Florida along with a donation to Catholic Charities of St. Petersburg.

"It's not uncommon for bishops and archbishops to make friendly wagers when their cities' teams face off in a Super Bowl, World Series or NHL final," Parkes said. "We wanted to make the wager not only fun, but meaningful, by including a donation to Catholic Charities."

Grob said the wager provides another way for the two communities to connect beyond the field.

"There's nothing like the excitement of the World Series to bring our two dioceses together in a spirit of friendly competition," Grob said. "While we're each cheering for our team to win, the real victory will be helping those in need through our Catholic Charities."

The Brewers enter the World Series after a 103-win regular season and are four victories away from the first championship in franchise history.

And across Milwaukee, plenty more than a trophy is riding on the outcome.
