HOUSTON >> The Houston Astros will soon have the most sparkling smiles in baseball.

Grammy-nominated Houston rapper Paul Wall has offered free grillz — precious metal covers worn over teeth — to every member of the team to congratulate them for reaching the World Series against the Los Angeles Dodgers.

“It’s a celebratory thing,” Wall said. “We want to celebrate with them, congratulate them, here’s a memorable, commemorative grill.”

Wall made the offer on social media Sunday, a day after the Astros beat the New York Yankees to capture the American League championship and advance to the second World Series in franchise history. Wall is offering the mouth jewelry through Johnny Dang & Company which he co-owns with Johnny Dang, who is better known in the rap world as TV Johnny.

Several players or their representatives have already contacted Wall to let him know they’d like one, and right-hander Lance McCullers tweeted that “a lot of the guys are hype for this.”

But would McCullers actually wear one?

“Definitely,” he said. “I would definitely get a grill.”

Wall, a lifelong Astros fan who watched games at the Astrodome from $1 seats as a child, said he got the idea to offer the team grillz after running into pitchers Justin Verlander, Dallas Keuchel and Tyler Clippard at a local steakhouse before the ALCS began.

“I was just joking around with them about it,” Wall said. “I said: ‘Hey man if y’all go to the World Series, I’m going to hook y’all up with some grillz.’ And they were like: ‘Hell yeah we want some grillz.”

Wall believes that grillz are a representation of the culture in Houston and his Grammy-nomination came for an ode to the jewelry he did with Nelly in 2005 that is aptly titled “Grillz.”

Wall’s grillz vary widely in price depending on what metal they’re made of and if they are encrusted with diamonds or other gemstones. The rapper himself has a platinum one with 20 carats of princess cut diamonds that set him back about $25,000. But to be clear, that isn’t the model he’s gifting to the Astros.

“The offer is solid gold grills maybe with the Astros emblem engraved on them,” Wall said.

But those aren’t just a drop in the bucket, with Wall estimating that a style like that would cost about $500.

“One or two is not too expensive, now if the whole 40-man roster wants a grill, oooh it could start getting expensive,” he said with a laugh. “But I’m a die-hard Astros fan and for me and TV Johnny to make grillz for them and congratulate them with a grill it means something, and that they would even accept or want a grill means a lot to me.”

He’s also open to getting grillz for people associated with the team who aren’t players, and loves the idea of buttoned up owner Jim Crane sporting one.

“We need to hook him up with a grill. (But) he probably doesn’t even know what a grill is, he’d be like: ‘What is it, gas or charcoal,’” Wall said cracking up.

He also wants Verlander’s model fiancee Kate Upton to know that he’s available if she wants to match her man.

“We’re going to hook her up with a rose gold, pink sapphire grill,” he said. “Yep, yep, we’ve got her grill ready, too. His and hers.”

Wall released an Astros-themed rap to commemorate Houston’s first trip to the World Series in 2005. But he has no plans for anything like that this time after the Astros were swept by the Chicago White Sox in that series after his song dropped.

“We jinxed them,” Wall said. “A lot of the rappers in town, we’ve got a rule right now where we’re not making no songs until it’s over. We need to chill out on these songs.”

That doesn’t mean he hasn’t put a few things together in case they finally win it all this season.

“I’ve already got like three of them wrote,” he said. “I’m just waiting to put them out.”
