“He said he feels a lot better,” Johnson said.

Johnson said he would warm up Burnett on Saturday and see if he is able to pitch. Burnett has had a history of flare-ups with his back.

“He’s had this before and if you’ve ever had a bad back, you know what I’m talking about,” Johnson said. “It’s kind of debilitating.”

On Friday, Johnson called for Burnett to warm up. But within five minutes, Johnson received a call back saying that the reliever’s back was bothering him but was still able to pitch. Johnson opted not to use him.

Burnett has appeared in three games this season, allowing two hits and striking out four hitters in 2 1/3 innings.
