It was the best streak by a closer in in Diamondbacks history. It's over now. But let's review.
The streak
Ziegler's 43 saves came against 19 of the 29 other teams in the majors, including at least one versus everyone else in the National. League. The Padres were his most frequent opponent (seven), just ahead of the Giants (six). The Rockies only gave Brad one save, so somewhat appropriate they were the ones to end it. Five times, Ziegler got saves on consecutive nights, six times, most recently on May 7th and 8th.
