White Sox Sign Right-Handed Reliever Dan Altavilla

The Chicago White Sox have announced the signing of right-handed reliever Dan Altavilla to a minor league contract. The MAS+ Agency client will join the team in spring training as a non-roster invitee.

Altavilla, 32, has experienced a tumultuous career in the big leagues due to frequent injuries. Since making his MLB debut with the Seattle Mariners in 2016, he has faced a series of setbacks, including shoulder inflammation, two UCL sprains (the latter leading to Tommy John surgery), a forearm strain, and a significant oblique strain that landed him on the 60-day injured list last season.

During his first three seasons with the Mariners from 2016-18, Altavilla pitched a total of 79 2/3 innings, posting a commendable 3.28 ERA, a 25.3% strikeout rate, and a 10.7% walk rate. However, his time on the mound has been drastically reduced since then. Over the past few years, Altavilla has managed just 40 big league innings with a combined ERA of 6.53. His minor league appearances have also been limited, with 84 1/3 innings pitched, totaling 120 1/3 frames over the past six years.

Despite his injury history, Altavilla’s early career performance shows promise. The White Sox are hopeful that he can return to form and provide valuable depth to their bullpen. As he prepares for spring training, Altavilla will aim to prove his resilience and earn a spot on the roster.
