Before I begin, I want to clarify that I’ll be looking at each team since the beginning of 2017, when the Colorado Rockies’ current contention window, as well as current core, began. I’ll kick things off with the Arizona Diamondbacks.
Of the four other teams in the NL West, Colorado has the most even head-to-head record with the Diamondbacks over the last three seasons. A quick search on Baseball-Reference.com shows that the Rockies sit one game over .500, with a 29-28 record, in that time against the snakes.
Arizona was one of the most active teams on the trade and free-agent market during the offseason.
