Montoya announced the arrival of daughter Manuela on Monday through his Twitter account.
Manuela joins brother Sebastian and sister Paulina. The 34-year-old Colombian said both mother and baby are doing great.
The birth following a rare NASCAR off week means Montoya will almost certainly be in Indianapolis this weekend for the 400-mile Cup race at Indianapolis Motor Speedway. Montoya is 21st in the standings a season after making NASCAR’s Chase for the championship.
NASCAR is in the midst of a baby boom this season: Jimmie Johnson, Carl Edwards and Elliott Sadler all became first-time fathers this year, and Jeff Gordon and his wife are expecting later this year.
