Wilhelmsen (#54) will be in uniform and available for today's (4:08 pm PT) game in Detroit.
The Mariners Major League, 40-man roster remains full.
Wilhelmsen, 32, was 11-10 with 67 saves and a 2.97 ERA (103 ER, 312.1 IP) with 294 strikeouts and 140 walks in 267 games, including 2 starts, in five seasons with the Mariners from 2011 to 2015. In 2015 with Seattle, Wilhelmsen was 2-2 with 13 saves and a 3.19 ERA (22 ER, 62.0 IP) with 60 strikeouts in 53 games.
Wilhelmsen is the Mariners all-time club leader in ERA (min. 300.0 IP) with a mark of 2.97. Wilhelmsen is also tied with Norm Charlton for the 5th-most saves in club history with 67. His 265 relief appearances with Seattle rank 6th in club history.
In 21 appearances with Texas this season, Wilhelmsen was 2-3 with a 10.55 ERA (25 ER, 21.1 IP) with 11 strikeouts.

He was originally played in the minors with Milwaukee in 2003 after being selected in the 7th round of the 2002 MLB First-Year Player Draft out of Tucson High Magnet School (Tucson, AZ).

In 21 relief appearances with Tacoma, Aro was 2-2 with 1 save and a 2.79 ERA (9 ER, 29.0 IP) with 22 strikeouts and 9 walks. Aro had posted 14 scoreless relief appearances, including 9 of his last 11 outings, with Tacoma.
