PHOENIX -- Brewers right-hander Jimmy Nelson took a three-day pause in his throwing program over the weekend, but he’s expected to resume activity on Tuesday, according to club officials who described the setback as minor.

“It’s arm fatigue/discomfort,” said president of baseball operations David Stearns. “It’s not specific to any particular location on the arm. We’re early in Spring Training; we’re basically skipping a ‘pen. I’m not particularly concerned right now.”

Said manager Craig Counsell: “There was just a little discomfort, and so we just went slow. It’s a very minor setback, and he’ll be back out [Tuesday] playing catch and moving forward again.”

Nelson underwent major shoulder surgery in the fall of 2017 and missed all of 2018. He navigated a normal offseason and had thrown four bullpens since arriving in Arizona, and he was advancing toward facing hitters in live batting practice.

Nelson will need to throw an issue-free bullpen session before moving on to that next step.

“Look, we’re being conservative,” Counsell said. “That’s first. There’s no red flags beyond that. It was really just three days we’ve slowed him down. We took Saturday, Sunday, Monday off. It’s just part of the bumps in the road in this thing that we need to get through.”

Nelson’s health is one of the prominent stories in Brewers camp, since he was the team’s top starting pitcher in 2017, when he struck out 199 batters in 175 1/3 innings before injuring his shoulder in a dive back to first base at Wrigley Field.

Stearns has monitored Nelson’s mound work and said he’s been impressed. The setback was so minor, Stearns said, that club officials might not have said anything had Counsell not specifically been asked about Nelson on Monday morning.

“These are the types of things that go on all the time during the season that we don’t tell you guys,” Stearns said. “A guy doesn’t feel great, we skip a bullpen and he pitches the next day or takes his regular turn. … If this continues for 10 days, then it becomes a little more significant. Right now, this is just a rest situation, and we’ll get him back on the bump when he feels right.”

Does it mean anything for Nelson’s readiness for the start of the season?

“I’ll let you guys do the calendar math at this point,” Stearns said. “Right now, our priority remains let’s get him feeling good, we’ll get him back on the mound, he’ll throw a bullpen, then he’ll throw a live [BP], then we’ll figure out where we want to go next.

“We’ve got seven -- hopefully eight -- months of baseball ahead of us. Where this lines up over the next five weeks is not a major concern for me.”
