The lone batter the D-backs walked did not come around to score, while eight of the 15 the Rockies walked did manage to score.
Especially with the way the ball has been flying at Coors Field lately, putting people on base is a recipe for disaster.
"Guys have been throwing strikes and going after the hitters," pitching coach Charles Nagy said. "They have aggressive swings. If you walk guys here, bad things happen."
Walks are an anathema to GM Kevin Towers and that's a philosophy Nagy shares. It certainly will be on the list for improvements for next season as the D-backs have allowed the second-most walks in the National League this year.
"Anywhere you walk guys it can come back to haunt you," Nagy said. "You walk the leadoff guy, he virtually always scores. You walk the pitcher and the next thing you know you give up five runs, so it's things like that. Here especially we want to make them earn it, put the ball in play, make them swing the bats."
