Manny Pacquiao became the fifth-oldest male boxer to win a world title on Saturday, winning by split decision over previously unbeaten Keith Thurman in Las Vegas.

Two judges scored it 115-112 in favor of Pacquiao, with one judge giving Thurman the edge at 114-113.

Pacquiao, 40, claimed the WBA welterweight title, improving to 20-4-2 all-time in world title fights. He's now 62-7-2 overall in his career.

The 30-year-old Thurman (29-1) entered the bout holding the "super" version of the WBA title, while Pacquiao held the "regular" version.

Thurman was making his fifth defense of the title he won in 2015 against Robert Guerrero.
