Benjamin Hochman: The Cardinals' Reyes keeps it interesting with walks, but always walks off with the save (so far)

The difference between reliability and being a liability is a reliever’s ability to avoid walking batters.

Except in the case of the Cardinals’ bullpen, in which the most reliable high-wire walkers often walk.

Perhaps no player is more conspicuous with this than Alex Reyes, the closer, who has walked 12 batters in 14 1/3 innings pitched.
