The Mariners swapped one reliever for another Thursday, recalling right-hander Hector Noesi from Triple-A Tacoma and optioning lefty Bobby LaFromboise.
Noesi, 26, will be available for Thursday's series finale against Detroit. He was transferred to Tacoma earlier this week after beginning the season in Double-A Jackson, where he went 1-0 without allowing an earned run in two starts.
One of the pieces in the Jesus Montero-Michael Pineda trade, Noesi made 18 starts for the Mariners last season, going 2-12 with a 5.82 ERA.
LaFromboise, 26, allowed a pair of earned runs in three relief appearances for the Mariners this season.
