Tolleson had been a perfect 13-for-13 in save opportunities since taking over as closer in May. But he suffered his first blown save on Saturday night when Yangervis Solarte hit a two-out, two-run home run in the top of the ninth inning that gave the Padres a 6-5 victory over the Rangers.
Tolleson had a 5-3 lead going into the ninth before the Padres rallied to win.
"Obviously I'm anxious to get right back out there," Tolleson said. "The guys played well, unfortunately we didn't come out on top."
Tolleson started the inning by getting Jedd Gyorko on a fly to deep center.
