[naviga:h3]Dixon wins IndyCar’s 1st race in 3 months[/naviga:h3]

FORT WORTH, Texas — IndyCar packed every bit of its delayed season-opening event into one long, hot day in Texas without any fans in the stands. Scott Dixon was the fastest for most of the day at a place he knows well.

Dixon, a five-time IndyCar champion, took the checkered flag at dusk Saturday for his fourth win at the 1 1/2-mile, high-banked oval, where drivers had also practiced and qualified earlier in the day. The 39-year-old New Zealander raced to his 47th career victory and matched A.J. Foyt’s record of 18 seasons with a win.

HAMPTON, Ga. — A.J. Allmendinger finally won on an oval.

He might just retire.

Taking advantage of mistakes by the three leaders, the 38-year-old Californian cruised to victory by nearly 2 seconds over pole-sitter Noah Gragson in the Xfinity Series race at Atlanta Motor Speedway on Saturday.

“Oh my god,” Allmendinger said as he climbed from his No. 16 Chevrolet. “I won on an oval.”

Indeed, he did.

Allmendinger, who first came to prominence in open-wheel racing, claimed a single victory during more than a decade in the top-level Cup series, and he had three previous Xfinity wins — all on road courses.

Now, he’s filled in a big hole on his resume.

[naviga:h3]MMA fighter McGregor retires for the 3rd time[/naviga:h3]

Conor McGregor has announced his retirement for the third time in four years.

McGregor abruptly made his latest dubious declaration Sunday morning on his Twitter account, where the former two-division UFC champion also announced his retirement in 2016 and 2019.

“Hey guys I’ve decided to retire from fighting,” McGregor wrote in a caption below a photo of him and his mother. “Thank you all for the amazing memories! What a ride it’s been!”

The 31-year-old Irish superstar revitalized his combat sports career in January with an impressive first-round stoppage of Donald “Cowboy” Cerrone at UFC 246. McGregor (22-4) hadn’t won a fight in a mixed martial arts cage or a boxing ring since 2016, but he remained the UFC’s brightest star and biggest financial draw.
