Cardinals claim Justin Miller off waivers from Nationals, move Jack Flaherty to 60-day injured list

The Cardinals have claimed Justin Miller off waivers from the Nationals, who recently designated the right-hander for assignment. St. Louis moved Jack Flaherty to the 60-day injured list to make room on the 40-man roster and optioned Roel Ramirez to clear an active roster spot, per MLB.com’s Jeff Jones. Moving Flaherty is largely clerical, as he was not expected to return from tearing his oblique before August.

Miller, 34, had trouble getting anyone out in his last appearance with the Nationals, turning a 5-0 relaxer into a bit of a nail-biter against the Mets. He gave up a two-run homer to Pete Alonso, followed by a solo shot to Billy McKinney. Kevin Pillar yanked another potential homer foul, but Miller recovered to strike him out.

Despite some rough outings this season, Miller has been a productive member of the bullpen in years past. He owns a 4.63 career ERA in 159 1/3 innings with the Nationals, Rockies and Tigers. He’s a fastball/slider guy who hasn’t had much life on the heater of late. All three home runs he gave up this season came on the four-seamer — averaging 93 mph, down just a touch from where it usually sits.

Ramirez, 26, made just one appearance for the Cardinals. He faced four batters, gave up one hit and two walks while tagged for three earned runs. Ramirez has options remaining, so he can be moved freely between Triple-A and the majors without being exposed to waivers.
