Tom Wilhelmsen out as Mariners closer

11 Comments

Last night’s soul-crushing loss to the Red Sox resulted in a demotion for Mariners closer Tom Wilhelmsen. The 29-year-old right-hander entered with a 7-2 lead, seemingly an easy finish to an easy game. He faced four hitters, allowing a walk, a single, a double, and another walk before being lifted. As other Mariner relievers — Oliver Perez and Yoervis Medina — failed to get the job done, Wilhelmsen was charged with four runs, raising his ERA to 4.37. The Red Sox eventually walked off 8-7 winners on Daniel Nava’s 8-7 single to center. As Dave Cameron pointed out on Twitter last night, the Mariners were 99 percent favorites to win, and they lost.

Geoff Baker of the Seattle Times informs us that Wilhelmsen is now out as the Mariners closer for the foreseeable future.

The team has not named an official interim closer. Interim manager Robby Thompson said, “We’ll try to piece it together and match up. And we’ll go from there.”

Wilhelmsen started off the season in fine fashion, carrying an 0.75 ERA through the end of May. Since June, however, he has an 8.10 ERA with an 18-18 strikeout-to-walk ratio in 23 and one-third innings. It’s not just Wilhelmen, though. Over the last 30 days, the Mariner bullpen as a whole has a 5.44 ERA, outpaced only by the Astros at 5.83. Demoting Wilhelmsen, while a good idea for the right-hander’s mental health, is rearranging deck chairs on the Titanic.
