Rookie left-hander Rob Rasmussen struggled to keep pitches down in the zone, allowing six straight hits, and Joe Beimel allowed a two-run home run to Prince Fielder as the Rangers' offense exploded for eight runs in the inning.
"I just didn't execute," Rasmussen said. "Our bullpen did a great job and picked up six innings before I came in there. I needed to pick us up and I just flat-out didn't execute, especially on that breaking ball. I left a lot of them up."
"Obviously it proved to be the game," Seager said of the 10th inning. "You get a guy on second with no outs and we had three shots at him and we weren't able to come through."
McClendon said his options were limited out of the bullpen as the game rolled deeper into extra innings.
"[Rasmussen], he's probably been overworked. I think he was three out of five coming into this ballgame. For a young kid that's tough," McClendon said. "Beimel was on fumes, he had nothing left. You talk about a gutsy guy on the mound when he had nothing. He came in and tried to get us out of the inning."
Seattle came into Saturday's game ranked 21st in the Major Leagues in bullpen ERA. While it was a weary bullpen that ultimately collapsed to end the ballgame, it was that same bullpen that kept the Mariners afloat for six innings after a rough four-inning start by Mike Montgomery. David Rollins, Mayckol Guaipe, Fernando Rodney and Tom Wilhelmsen combined to allow just four hits between the fifth and 10th innings. It was a strong all-around performance, but one the bullpen couldn't sustain beyond the 10th.
"We had six scoreless innings, it was a hell of a ballgame," McClendon said. "Things just got out of hand in the 11th."
