Gallardo sprained his left ankle on Tuesday in a loss to the Atlanta Braves and skipped his regular bullpen session on Thursday. According to MLB.com, Gallardo threw off flat ground on Friday and declared himself fit, but Roenicke said there were other concerns besides merely being able to pitch.
Nelson was scratched from his scheduled start for Triple-A Nashville on Friday and will join the Brewers in Miami on Saturday. He is not expected to be in uniform until Sunday, when the Brewers will have to make a corresponding move to put Nelson on the 25-man roster.
Nelson made one start and three relief appearances for the Brewers last September, allowing just one earned run and striking out eight in 10 innings of work. He allowed only two hits and walked five.
In nine starts for Nashville this season, Nelson is 5-1 with a 1.71 ERA and 0.931 WHIP in 58 innings, striking out 58 and allowing one home run.
He was the Brewers second-round pick in 2010 out of the University of Alabama. The 24-year-old right-hander split last season between Double-A Huntsville and Nashville before getting a September call-up.
Gallardo, 28, is 2-3 this season with a 3.51 ERA and 1.254 WHIP in 10 starts, striking out 41 in 59 innings while surrendering seven home runs.
“I know myself pretty well that it’s not bad,” Gallardo said Friday. “It’s nothing that’s going to alter some of the things I do on the mound or stuff like that. I’m satisfied with the flat ground I threw today.”
Roenicke agreed the session went well, but had other concerns.
“There’s still reasons why we’re a little bit concerned with having something controlled like a bullpen and being in a game where they can bunt on him, he’s got to cover first, he’s going to have ground balls hit right back at him, he’s got to run the bases,” Roenicke said.
Nelson will become the first pitcher other than the five starters Milwaukee broke camp with in March to start a game this season.
