Manny Pacquiao tells Ronnie Nathanielsz of the Inquirer that he's still hungry and hasn't grown tired of the grind that comes with preparing for his big fights, as he started training on Monday for his November 12 trilogy bout with Juan Manuel Marquez.

"Boxing gave me life from the time I was a kid," he told the Inquirer. "This is my job. I need to work well and train hard. I am not tired of boxing."

Pacquiao went five rounds on the punch-mitts, worked on the two-ball and the speed ball, skipped rope and did his usual abdominal exercises.

... Explaining why he started training early for the Marquez trilogy, Pacquiao said "it's better to warm up early. This is the start of my training which I actually started on Monday and will continue."

Pacquiao won't start his full camp with Freddie Roach for a little while yet, but obviously he's not overlooking Marquez. Bob Arum says that he's glad Manny is already working out, because he feels Marquez's counter-punching still gives him a great shot against Pacquiao. The two went to a draw in 2004, with Marquez rallying to win much of the fight after being dropped three times in the first round, and then to a controversial split decision in 2008, which Pacquiao won. Opinions seem split pretty evenly on both fights, with some feeling Pacquiao won both, and some feeling Marquez won both. The record books show Pacquiao as 1-0-1 against his greatest rival, and now they'll do it again.
