Mariners reliever Juan Nicasio is scheduled to undergo season-ending knee surgery, Ryan Divish of the Seattle Times tweets. It seems the procedure will be “cleanup surgery, nothing catastrophic,” Corey Brock of The Athletic adds.
Nicasio has dealt with right knee issues throughout the season and endured multiple stints on the disabled list as a result. The 31-year-old last pitched Aug. 2, when he allowed two earned runs in two-thirds of an inning in a loss to Toronto. He’ll wrap up his season with a hideous 6.00 ERA across 42 innings, though FIP (2.99), xFIP (3.17) and SIERA (2.58) suggest Nicasio deserved far better in the run prevention department. Nicasio logged excellent strikeout and walk rates (11.36 K/9, 1.07 BB/9), to his credit, and he was victimized by an unusually high batting average on balls in play (.402) and an abnormally low strand rate (58.1 percent).
Assuming Nicasio returns at full strength in 2019, the Mariners will hope he experiences some positive regression during what will be a contract year. Seattle signed Nicasio to a two-year, $17MM guarantee in free agency last winter, but the deal obviously hasn’t panned out thus far for the club.
