The 105th Running of the Indianapolis 500 takes place Sunday (12:45pm ET, NBC), back in its normal Memorial Day weekend slot after moving to August last year.

Why it matters: 135,000 fans (40% capacity) will be in attendance at the enormous Indianapolis Motor Speedway, making this the largest sporting event since the pandemic began.

  • At 253 acres, the infield — which won't be open this weekend — is so big that several other sports venues and international landmarks could fit inside.

The field: 33 drivers have their sights set on hoisting the Borg-Warner Trophy, led by New Zealander Scott Dixon, sitting in pole position.

  • Past winners: Dixon ('08 champ) is one of nine racers in the field with at least one Indy 500 victory. Hélio Castroneves ('01, '02, '09), Juan Pablo Montoya ('00, '15) and Takuma Sato ('17, '20) are three of just 20 racers who've won multiple times.
  • Fun fact: 33 isn't an arbitrary number. Organizers determined 1911's 40-car inaugural race was too crowded, and wanted each car to have 400 feet between them if evenly dispersed on the 2.5-mile track; 2.5 miles (13,200 feet) divided by 400 feet equals 33.

The intrigue: Simona de Silvestro is making her sixth start in the race, but this time she'll be part of women's sports history.

  • Four of her seven over-the-wall pit crew members are women, the most in motorsports history. Her two spotters, two of her engineers and the entire front office at Paretta Autosport are also women.
  • "My hope is that in five years, us being a team of mostly women is the least interesting thing about us," owner Beth Paretta told ESPN.

Children were among up to 17 American Christian missionaries and their relatives kidnapped by a gang in Haiti on Saturday, the New York Times first reported.

Details: The missionaries had just left an orphanage and were traveling by bus to the airport to "drop off some members" and were due to travel to another destination when the gang struck in Port-au-Prince, Haitian security officials said, per the NYT.

Melbourne, "world's most locked-down city," to lift stay-at-home orders

Melbourne's stay-at-home orders will end five days earlier than planned, officials in Australia's second-biggest city announced Sunday.

Why it matters: The capital of the state of Victoria has had six lockdowns totaling 262 days since March last year. That means Melbourne spent longer under lockdown than "any other city in the world" during the pandemic, Reuters notes.
