Casali adds some depth behind Seattle starter Cal Raleigh. The 33-year-old backstop has had a nice showing in limited playing time with the Giants this season. Through 102 plate appearances, Casali is hitting .231/.325/.370, connecting on four homers and a trio of doubles. That’s a nice blend of power and patience from a depth catcher, even when paired with Casali’s typically lofty level of swing-and-miss.
Seattle’s #2 backstop Luis Torrens has underwhelmed this year, hitting .208/.262/.225 in 42 games. Torrens can’t be optioned to the minor leagues, so Casali’s addition could conceivably squeeze him off the 40-man roster entirely. Raleigh will continue to play most days amidst a breakout season, and the M’s may not want to carry three backstops on the active roster. Casali is currently on the injured list after suffering an oblique strain last month, but he’s on a rehab assignment and should be reinstated to the majors shortly. Casali is making $2.6MM this season, around $928K of which has still to be paid. He’ll be a free agent at season’s end.
Stryffeler is a 26-year-old reliever who’s spent the 2022 campaign in Double-A. A right-hander, he owns an excellent 2.27 ERA through 35 2/3 frames. Stryffeler has fanned an elite 37.7% of batters faced but walked an elevated 12.6% of opponents. The Lake Erie college product will be eligible for the Rule 5 draft this winter if he’s not added to San Francisco’s 40-man roster.
