Castroneves and Takuma Sato, who won the Indy 500 twice, took to social media overnight to pay tribute to Al Unser.

“RIP AL SR … you will b missed!” Castroneves captioned an Instagram post.

“Rest In Peace an incredible three time @IndyCar champion and four time #INDY500 winner Al Unser,” Sato tweeted. “It was my absolute honor to attend his baby @BorgTrophy ceremony. His speech was very funny and so charming. Huge respect. My deepest condolences to his family.”

In addition to his wife, Unser is survived by his son, two-time Indy 500 winner Al Unser Jr., the AP reported. Two daughters, Mary and Deborah, preceded him in death.
