Ohlendorf first felt them against the first hitter, and he went on to let all four hitters he faced reach base. He'll be re-evaluated Friday morning. Ohlendorf also has dealt with tightness in his side this spring.
Julio Teheran tallied four strikeouts across three scoreless frames in Thursday's win over the Nationals.
He allowed four hits and walked one, dueling with Jordan Zimmermann before they each handed it off to the bullpen. Teheran hasn't been scored on in his first five innings of Grapefruit League action. He'll be looking to follow up this year on an amazing rookie season that saw him put up a 3.20 ERA over 30 starts.
Jordan Zimmermann struck out four over three scoreless innings against the Braves Thursday.
Zimmermann gave up two singles and walked one on the night. The studly right-hander is now unscored upon in his first five Grapefruit League innings. Zimmermann has posted a 3.12 ERA over the last three years for the Nationals, covering 90 starts.
