With Huston Street unavailable, Luke Gregerson notched his fourth save of the season with a scoreless frame in Tuesday's win over the Pirates. Gregerson issued a two-out walk to Neil Walker, but he got a third groundout of the inning to end it. The righty now holds a 2.83 ERA and 58/17 K/BB ratio over 60 1/3 frames this season. With Street due back Wednesday, Gregerson will slide back into a setup role.
