Known for being one of the more prolific Pinch Hitters of all-time, Denny Walling was a Houston Astro for 13 of his 18 seasons and was predominantly used against right handed pitchers.  Walling was especially effective with his bat in the cavernous Astrodome and the fact that he was capable of playing multiple defensive positions made him an asset for Houston.  He would have 726 Hits for the club.
