Nationals pitcher Doug Fister and Sammy Solis were both able to throw off a flat surface on Wednesday, manager Matt Williams said per MASN Sports.
Fister, who is dealing with a strained flexor, threw for the first time since suffering the injury. Fister is 2-2 with a 4.31 ERA in 39 2/3 innings of work. Solis, who is dealing with shoulder inflammation, has not pitched since May 10 with the injury.
