LHP LUIS AVILÁN
The Mariners have struggled to acquire bullpen help in free agency, especially from the left-hand side (we’re looking at you, Marc Rzepczysnki). With the departures of James Pazos and Zach Duke, Seattle’s very limited with left-handed options for their ‘pen with just Roenis Elías and Zac Rosscup currently on their 40-man roster.
Enter Luis Avilán, who was non-tendered by the Phillies back in November. The 29-year-old southpaw had a solid year for the White Sox and Phillies, posting a 3.09 FIP and 10.13 K/9.
Where Avilán struggled was with damage control, only notching a left-on-base percentage of 70.2%. That’s a solid indicator of why there’s such a massive gap between his innings totals (45.1) and his 70 appearances.
Avilán is also the true definition of a LOOGY, which is basically like acquiring half a pitcher. In 2018, left-handed hitters slashed .217/.304/.341 against Avilán, whereas righties hit for .277/.346/.387.
Those numbers against lefties will keep him in the league for some time, however. Even with the negatives, Avilán’s been a serviceable pitcher and could provide some value for the Mariners come July or August.
