Diamondbacks signed RHP Tom Wilhelmsen to a minor league contract with an invitation to spring training.

The right-hander was released by the Mariners in late November. He struggled to the tune of a 6.80 ERA and 28/19 K/BB ratio over 46 1/3 innings between the Rangers and Mariners in 2016. The 32-year-old could compete for a spot in the Opening Day bullpen with a strong showing in the spring.

Mariners released RHP Tom Wilhelmsen.

Wilhelmsen, who would have been arbitration-eligible this winter, was designated for assignment on Friday. The 32-year-old right-hander posted a rough 6.80 ERA and 28/19 K/BB ratio over 46 1/3 innings this past season between the Rangers and Mariners, though he was much better after returning to Seattle.

Mariners designated RHP Tom Wilhelmsen for assignment.

The 32-year-old hurler began the season with the Rangers before returning to Seattle later in the season. In 29 appearances with the M's, he registered a 3.60 ERA, 1.28 WHIP and 17/10 K/BB ratio over 25 frames. It wouldn't be surprising to see them re-sign the veteran right-hander to a minor league deal.

Mariners activated RHP Tom Wilhelmsen from the 15-day disabled list.

Wilhelmsen missed almost two weeks of action due to a lower back strain, but he's fully recovered and ready to go. He'll see most of his work in middle relief for the M's over the final three weeks.

Tom Wilhelmsen (back) threw a simulated inning without issue on Thursday.

He's expected to be activated from the disabled list and return to the Mariners bullpen on Saturday in Oakland. Given the current depth that the M's have in the late innings, he's expected to function in a middle relief role upon his return.

Tom Wilhelmsen (back) is scheduled to throw a simulated inning Thursday.

Wilhelmsen is expected to be ready to return from the disabled list when first eligible next week. He's been out since late August because of a lower back strain.

Mariners placed RHP Tom Wilhelmsen on the 15-day disabled list with a lower back strain.

His injury, as well as recent overuse of the bullpen, is the reason the M's needed to recall a couple of fresh arms on Saturday. The 32-year-old hurler has pitched well for the Mariners, registering a 3.20 ERA, 1.17 WHIP and 15/7 K/BB ratio over 19 2/3 innings.

Mariners recalled RHP Tom Wilhelmsen from Triple-A Tacoma.

Donn Roach was sent down in the corresponding move. Wilhelmsen signed a one-year deal with the Seattle last week after getting released by Texas. He owns a lousy 10.07 ERA over 22 appearances this year.

Mariners optioned RHP Tom Wilhelmsen to Triple-A Tacoma.

Wilhelmsen signed a one-year deal with the Mariners this week and will remain with the organization after passing through optional waivers. The veteran right-hander figures to join the major league bullpen relatively soon.
Fri, Jun 24, 2016 06:46:00 PM

The Mariners have placed Tom Wilhelmsen on optional waivers.

The waivers are revocable, so in the unlikely even that Wilhelmsen is claimed, the M's can pull him back. Seattle signed Wilhelmsen on Wednesday after he was released by the Rangers, but they want the reliever to get some fine-tuning at Triple-A Tacoma before they add him to their bullpen.
Fri, Jun 24, 2016 12:45:00 PM

Mariners signed RHP Tom Wilhelmsen to a one-year contract.

Wilhelmsen elected to become a free agent last week after getting pushed off the Rangers' 40-man roster. He'll rejoin the Mariners ahead of Wednesday's game in Detroit. The right-hander had a brutal 10.55 ERA in 21 appearances this season with Texas, but he was excellent for Seattle in 2014-2015.

Tom Wilhelmsen has elected free agency.

Wilhelmsen cleared waivers after being designated for assignment, but he's decided to look for a job elsewhere. He held a 10.55 ERA in 21 outings for the Rangers, but a career 2.97 ERA and nearly a strikeout per inning entering the year could get him a major league contract.
Fri, Jun 17, 2016 03:18:00 PM

Rangers optioned RHP Tom Wilhelmsen to Triple-A Round Rock.

It's back to the drawing board for Wilhelmsen, who owns a dismal 10.55 ERA in 21 outings this year. Nick Martinez was called up to take his spot on the active roster. It could be a while before Wilhelmsen gets another chance in Arlington.
Tue, Jun 14, 2016 08:16:00 PM

Rangers recalled RHP Tom Wilhelmsen from Triple-A Round Rock.

Wilhelmsen holds a 9.37 ERA and 2.08 WHIP across 18 relief appearances for the Rangers this season. He'll be used in the middle innings.
