Rockies chasing walk-off history in 2014

Colorado just one short of club's single-season record 10 walk-off victories

Rockies chasing walk-off history in 2014

DENVER -- Believe it or not, the 2014 Rockies are gunning for a franchise record when it comes to walk-off wins.

Wilin Rosario's towering, two-run walk-off homer in Thursday's 7-6 win over the D-backs gave the Rockies nine walk-off victories on the season. That's one shy of tying a franchise record set by the 2010 Rockies, who had 10 walk-off victories on nine hits and a sacrifice fly.

To put that number in perspective, 15 percent of the Rockies' 62 wins this season entering Friday have been of the walk-off variety.

Best-case scenario, the Rockies can finish with a 71-91 record this season. The 2010 squad that owns the walk-off record finished four games over .500 (83-79).

Three of the Rockies' walk-offs this season have come in September as Charlie Blackmon and Drew Stubbs each hit walk-off singles this month.

Rosario's walk-off homer -- the first of his career -- traveled an estimated 447 feet, landing on the left-field concourse.

As manager Walt Weiss put it, the blast went about "as high as it went far." But even with its pop fly-esque trajectory, Weiss knew it was a no-doubter.

"The way it came off the bat, I knew the park wasn't going to hold it," Weiss said Friday.
