"We are going to continue to look for the best possible matchups and find guys who can get us outs," Banister said. "I still believe in these guys. They have a proven track record. They are quality bullpen shutdown pitchers. But they have been challenged.
"That's why we continue to search for the right mix and the right matchups."
Prior to Boston, the Rangers went through an 11-game stretch in which the bullpen was outstanding. During those 11 games, Rangers relievers had a 1.83 ERA, a .093 WHIP and a .207 opponents batting average.
But they have allowed 12 runs in 4 2/3 innings in two games against the Red Sox.
