The Rockies have been in a four-week funk. Sitting atop the NL West the morning of May 30, the Rockies were not only denied a sweep of a three-game series with the Giants at Coors Field that afternoon, but that 7-4 loss sent them on a skid that has them in a free-fall, landing in fourth place in the division, six games back of the first-place Diamondbacks.

There was a sign of life last week. The Rockies put together a four-game winning streak with three consecutive wins against the Mets, and one against the Marlins, but then the struggle that has engulfed the Rockies returned. They lost back-to-back games to a Marlins team that at the time had the worst record in the NL.

So after having a chance to catch their breath on Monday, the Rockies now embark on a week-long challenge to avoid any further damage to their post-season hopes.

And it is a challenge.

They find themselves this week playing three-game series against the Giants at AT&T Park starting Tuesday night and then a three-game weekend visit to Dodger Stadium -- two cities in which the Rockies have had their biggest challenge winning games in their history.

This year, the Rockies lost two of three at Dodger Stadium, and then were swept at home by the Dodgers, and had a bit of success against the Giants, splitting four games at AT&T Park and winning two of three against the Giants at Coors Field.

The Rockies .454 winning percentage in San Francisco is their fifth worst out of the 14 current NL cities. They have won only 13 of 54 series played at AT&T Park, and split six others.

They have a .424 all-time winning percentage at Dodger Stadium, the second worst of any NL city to Atlanta, where they have now played the Braves in three ballparks without success.

And as if the Bay Area isn't challenge enough for the Rockies, they finish up at AT&T and then head, south to Los Angeles.

There is not a player on the Rockies roster who, wearing a Rockies uniform, has hit .300 at Dodger Stadium. Charlie Blackmon is the team leader at .284.

Only six Rockies position players have even hit .200 in their days with the franchise at Dodger Stadium.

Now, Nolan Areando has hit only .253 and Carlos Gonzalez .249, but they have shown power. Arenado has nine home runs at Dodger Stadium, two more than Gonzalez.
