Ranking the five best acquisitions the Mariners have made so far this off-season

#4 RHP Anthony DeSclafani

Anthony DeSclafani is a veteran starting pitcher who can work as a fill-in starter or long reliever for the M's. The Mariners rotation is likely set with Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller, and Bryan Woo. DeSclafani is a nice depth piece who can make a spot start if one of these pitchers gets hurt or has a bad day on the mound. The Mariners could have used an arm like this last season, as they did not have a long relief option as they did in previous seasons. With the acquisition of DeSclafani the Mariners now have a new Chris Flexen/Matt Boyd type relief option in their bullpen.

For his career, DeSclafani has a 4.20 ERA in nine seasons. In 2023, DeSclafani had a 4.88 ERA and made 18 starts as a pitcher for the San Francisco Giants. Last season, DeSclafani started strong with a great first month in which he went (2-1) with a 2.70 ERA. His numbers dropped off after that, as he went (2-3) with a 4.10 ERA in May, was (0-3) with a 6.65 ERA in June, and (0-1) with a 10.61 ERA in two starts for the month of July. Serving in a smaller role as a fill-in starter and long reliever could be good for DeSclafani, as his durability has been an issue the past two seasons.
