Tom Wilhelmsen back in role as M’s closer

OAKLAND, Calif. – The biggest test is yet to come to determine whether this is a new-and-improved Tom Wilhelmsen at the back end of the Mariners’ bullpen.

Wilhelmsen hasn’t yet had to bounce back from a bad performance. So far he’s been close to perfect: 9 2/3 scoreless innings in eight appearances, and eight saves, since reclaiming his former closer’s role in late August.

But Wilhelmsen, at 31, believes he’s better equipped to handle that adversity, whenever it comes, than he was two years ago.

“I’ve learned quite a bit in the absence that it’s been,” he said. “Learning how to deal with successes and failures. How to bounce back … by watching (Fernando) Rodney and some of the other guys.”

Wilhelmsen’s stuff has never been an issue.

“Listen, Tom is not a neophyte at the job,” manager Lloyd McClendon said. “He’s done it before. He seems to be a lot more relaxed. His pace is good. His breathing is good. He’s commanding the zone.”

This is no small thing. Fixing the bullpen looms as the Mariners’ top off-season priority. Finding a reliable closer is step one in that process. What if that guy is already onboard?

“He’s done great,” McClendon said. “I think he’s had time to sit back, in his different roles, and reflect. I certainly don’t think he’s overwhelmed by any means in these type of situations.

The key: He’s done it before – and he’s been successful in doing it.

Wilhelmsen replaced Brandon League as the Mariners’ closer on June 4, 2012 and compiled a 1.76 ERA in 48 games over the remainder of the season while converting 29 of 33 save opportunities.

The following year, Wilhelmsen was 11 for 11 with an 0.50 ERA through 17 appearances before it started to go south. Wilhelmsen compiled a 6.75 ERA over his next 30 outings and by August surrendered his closing responsibilities.

By last season, Wilhelmsen was pitching long relief – and doing well; he had a 2.27 ERA in 57 games. But a tough stretch this year, while performing in the same role, resulted in a brief remedial stretch in the minors.

Wilhelmsen was better once he returned after the All-Star break but it was desperation that prompted McClendon to reinsert him as the closer.

Wilhelmsen points to some changes since he last served in the role.

“I haven’t been throwing the changeup as much lately,” he said, “but I think the slider is becoming a little sharper. I’m starting to have success with it against lefties, and that’s something I was always afraid to throw.”

Mostly, though, Wilhelmsen simply believes he is better prepared mentally.
