The San Francisco Giants
The San Francisco Giants, comparatively speaking to the Dodgers, are less of a threat to the Rockies in the Wild Card spots or division.
Along the same lines as the Dodgers, though, they almost certainly won’t send one of their biggest names to a team in the same division. However, if they are, the Rockies could REALLY use a Madison Bumgarner, who is a free agent after this season if the Giants don’t exercise their team option for $12 million for next season.
However, in thinking of more realistic terms, Pablo Sandoval might be an option for the Rockies. He was a total bust for the Boston Red Sox but he has been better since he returned to San Francisco. In 2018, he has a slash line of .263/.326/.388, which is obviously much better than the Rockies current infield bench options. He has also played third base, first base, and, believe it or not, second base for the Giants this year.
The career .344/.389/.545 postseason hitter could also provide the Rockies a good bench bat with 39 games of postseason experience, including three World Series rings and a World Series MVP.
He is making league minimum this year and is a free agent after the season so he is another option that, while in the Rockies division, could be a potential target.
