Lou Trivino could be an asset in a needy Red Sox bullpen but the 30-year-old righthander would slot only into the back end of the Seattle bullpen.
Steamer projects Trivino with a 2022 WAR of 0.0 in 71 appearances while MLB Trade Rumors projects a $2.9 million salary.
Even with significant regression from the overperforming Seattle bullpen, here are the 2022 projections for Mariner relievers:
Ken Giles $5.25 million, 0.3 WAR in 54 appearances (1.8 fWAR in 2019)
Diego Castillo $2.6 million, 0.6 WAR in 61 appearances (0.7 fWAR in 2021)
Drew Steckenrider $2.1 million, 0.1 WAR in 66 appearances (1.3 fWAR in 2021)
Paul Sewald $1.8 million, 0.5 WAR in 67 appearances (1.4 fWAR in 2021)
Casey Sadler, $1.3 million, 0.4 WAR in 60 appearances (1.1 fWAR in 2021)
Anthony Misiewicz, league minimum, 0.3 WAR in 58 appearances (0.5 fWAR in 2021)
Andres Munoz, $750,000, 0.5 WAR in 46 appearances
The Mariners would likely let Trivino, with his projected 0.0 WAR and $2.9 million salary, pass through waivers to a needier franchise.
