The Phillies on Saturday transferred starter Jerad Eickhoff to the 60-day disabled list, ending the right-hander's season.
Eickhoff left his last start Wednesday in the third inning with what the team called "nerve irritation" in his right throwing hand.
Eickhoff, arguably the Phillies' most consistent starter last season, has had a down year. He's also seen his velocity dip. His fastball had averaged under 90 mph in six of his previous nine starts. The 27-year-old righty insisted that his health up to that day had not been an issue.
"I just kind of felt it in the third inning there," he said after the game. "I felt tingling in my hand. Almost like a numbness and a weakness in it. I just couldn't exactly feel the baseball. That's never a good thing. It's something going on with a nerve, maybe. Where, exactly, I'm not sure. It's definitely a nerve issue."
Part of the return from the Rangers for Cole Hamels, Eickhoff finishes his second full season with the Phillies 4-8 with a 4.71 ERA in 128 innings.
In a corresponding move, the Phillies claimed LHP Kevin Siegrist off waivers from the Cardinals. Siegrist, also 27, has struggled this season (4.98 ERA) but was excellent for St. Louis in 2015 and 2016. In those seasons combined, he posted an impressive 2.44 ERA in 148 appearances. He also struck out 156 batters in 136 1/3 innings during that span.
