The National League baseball club officially announced the contract Tuesday, the day after several media outlets, including The Denver Post, reported the lucrative deal that will keep Tulowitzki in a Rockies uniform through the 2020 season.
Tulowitzki, 26, had signed a six-year contract in January 2008 after helping the team get to its first-ever World Series in 2007. He voiced high hopes for bringing a world championship to Denver.
"We're going to win here. We're going to do it," Tulowitzki said. "We've got a good team here. If we don't win a World Series around here, then it's a failure. I have high expectations, and we're going to meet them."
Tulowitzki batted a career high .315 in 122 games last season and earned his first Gold Glove award. He is a career .290 hitter with 92 homers in 554 games.
"This decision represents everything that we believe in," Rockies General Manager Dan O'Dowd said. "It's a commitment on the part of our owners ... . I can't say it any more plainly than it's about our team."
