The Texas bullpen was a long, exhausting storyline for much of the season’s first half. Time and time again, Longhorn starters did their job — only for things to unravel late. Ole Miss is a prime example; a pair of walks and hit batters from Thomas Burns and Cal Higgins set the stage for a two-out grand slam by Tristan Bissetto that handed Texas its first defeat of the year. Recently, though, that narrative had quieted. The bullpen had steadied. The late-inning collapses had, for the most part, disappeared. That was until Saturday, of course.  Ruger Riojas delivered one of his best performances in weeks, striking out seven and allowing just three hits without issuing a walk.
