The Milwaukee Brewers ' Christian Yelich got a new 'do and joined a lip-synching boy band.

Yes, really — if only for half a day.

Its other members: Dansby Swanson of the Chicago Cubs and Dustin May of the Los Angeles Dodgers.

Their debut music video ? A spoof on a baseball classic. Hint: It plays during the tradition that is the seventh-inning stretch.

"Take Me Out to the Ball Game" meet “Take Me Out to the Bald Game." The three athletes and their luscious locks spent hours in hair and makeup getting bald caps installed.

From the song to the makeovers, all of it was for DIRECTV's latest national advertising campaign — "Nothing On Your Roof 2.0." Get it? — to promote the company's satellite-free MLB streaming offerings .

This comes after last year's "Nothing On Your Roof 1.0" campaign , which featured San Francisco 49ers superstar tight end George Kittle — a Wisconsin native — with his "footbald" helmet.

Yelich was approached about the campaign in early March. After hearing about the concept and who his co-stars would be, he was in.

He was a fan of its uniqueness, comedy, lightheartedness — and that he'd be filming it with fellow MLB-ers.

"I think a lot of people are going to get a good laugh out of it," Yelich told the Journal Sentinel in a recent Zoom interview.

Immediately after the Brewers' final preseason game of the year March 24 — which they won — Yelich went from the Colorado Rockies' spring training ballpark to Scottsdale Stadium, where the commercial would be filmed.

"It was a bigtime set, big production, a lot of effort from a lot of people," Yelich said.

The DIRECTV campaign was created in collaboration with creative agency TBWA\Chiat\Day LA, a news release said. While Yelich got his parts ahead of time, he said, some adjustments were made on the spot.

The ad kicks off with Swanson, Yelich and May in barber chairs, awaiting fresh cuts. That chunk was filmed on a barbershop set on-site, Yelich said.

Yelich was off to hair and makeup next, which took a couple of hours. He recalled getting his hair gelled down and a rubber-looking cap being put on. Airbrush makeup was used to blend the cap into his skin and hair was glued onto the back and sides of his head.

"It actually looked like it was real," Yelich said. "It looked like you were actually bald. They did a great job."

The athletes got to watch each other film their solo sections of the commercial: May went first, then Swanson and, last but not least, Yelich. That led to some good laughs, Yelich said.

"It was fun. I've known them kind of over the years just playing against them and stuff like that," Yelich said. "It was cool to spend a couple of hours together."

While it was a "long, long, long" day — Yelich's started at 7 a.m. and he got home after midnight — it was all good with him.

"It was a good time," Yelich said. "I really enjoyed it and had fun with it. It was a fun shoot and a cool way to wrap up spring training."

When Yelich got home from the shoot, he finished packing to leave the next day for New York for the start of the regular season, which began March 27.

What will the DIRECTV 'Nothing On Your Roof 2.0' campaign look like?

The campaign, featured on social media, will include a Snapchat lens, CTV and digital out-of-home billboards starting April 29, according to a news release.
