Chris Flexen, who was scratched from a scheduled start earlier in spring training due to soreness in his right knee, has undergone surgery to remove a bone chip from the aforementioned knee.

“It was frustrating, especially not knowing until the day of,” Flexen said of discovering the bone chips. "I had zero problems, zero pain, zero hiccups, nothing. Just woke up with it swollen."

With an expected recovery time of roughly two-to-three weeks, the right-hander will likely begin the 2017 season on the disabled list. The 22-year-old, who was recently added to the 40-man roster, had a 3.56 ERA in 134 innings with the St. Lucie Mets last season and was a likely candidate to be tabbed for the Opening Day start for the Binghamton Rumble Ponies’ inaugural game.

Amazin’ Avenue ranked Flexen the Mets’ 21st top prospect going into the 2017 season. His fastball sits in the mid-90s, topping out at 96 MPH, and gets good arm-side tailing action. His curveball has the makings of being an average-to-above-average offering. He complements the fastball and curveball with a changeup and a slider, the former of which has shown some promise.
