PITTSBURGH -- Roberto Clemente's iconic No. 21 has been a fixture in Pittsburgh for more than 60 years. Its presence has only grown since the Hall of Fame outfielder's death at age 38 on New Year's Eve 1972 in a plane crash off the coast of his native Puerto Rico.

His jersey remains one of the franchise's most popular. It adorns the right-field wall named after him at PNC Park. It's ubiquitous in the stands during Pirates home games and on postgame strolls along the Allegheny River. First-year manager Derek Shelton has even seen his neighbors rocking it while cutting the grass.

On Wednesday night, the number found itself in a place where it hasn't been for nearly a half-century: on the back of a member of the Pittsburgh Pirates. All of them.

The Pirates celebrated Clemente's legacy by wearing his number during the organization's first "Roberto Clemente Day" on Wednesday against the Chicago White Sox. The number was mowed into the right-field grass a few hundred yards from where Clemente stood at Three Rivers Stadium.

"He's our Jackie Robinson," said current right fielder Gregory Polanco, who is from the Dominican Republic. "He's our idol. He's the Great One, man. He's the player we all know growing up, like, 'Hey, Clemente. He was the man. It was outside the baseball field. That's what makes it even more, the greatest person, what he did and the way he was helping people always."

Major League Baseball granted the Pirates permission for everyone to don No. 21 last week, then extended it to all Puerto Rican-born players. Detroit pitcher Joe Jimenez and Milwaukee hurler Alex Claudio were among the Puerto Rican major leaguers who took part in the celebration. Clemente's family and the team he represented are hoping the league will one day honor Clemente by retiring his number across all of MLB as it did for Robinson's No. 42 in 1997.

"He deserves that," Polanco said.

The Pirates made sure to extend the tribute beyond the walls of PNC Park, where the Roberto Clemente Bridge stands. The team partnered with the Greater Pittsburgh Community Food Bank to host a drive-through food distribution early in the day. They hosted a meal and mask distribution at the Latino Community Center and bought gift subscriptions to the New Pittsburgh Courier -- a newspaper focusing on the city's Black community -- for local libraries.

"One of the things that we have talked about a lot is Roberto Clemente, the player, is one of the greatest players of all time," Shelton said. "Roberto Clemente, the humanitarian, was probably the greatest humanitarian in the history of our sport."

The day was also celebrated in Clemente's hometown of Carolina, Puerto Rico, and elsewhere across the island. Pirates third-base coach Joey Cora, born in Caguas, Puerto Rico, received pictures from back home of Puerto Ricans wearing their own No. 21 jerseys.

"This is something when we first started, it was a really cool initiative, but the fact that it has grown into what it has grown into, the fact that all the Puerto Ricans will be able to don his uniform today, it's pretty cool," Shelton said. "It got a lot bigger, a lot faster, than I thought, but again, it's something that I'm extremely proud to be part of."
