PHOENIX -- Catching prospect Jacob Nottingham, sidelined of late by a sore throwing arm, was among four players reassigned to the Brewers' Minor League camp on Wednesday to continue comebacks from injury.
The three others are all rehabbing from 2016 surgeries: Pitchers Adrian Houser (elbow) and Yhonathan Barrios (shoulder) and outfielder and 2016 first-round Draft pick Corey Ray (knee). Houser is on the 40-man roster, so the Brewers used the second of three Minor League options to send him down.
Nottingham, No. 14 on MLBPipeline.com's list of the top 30 Brewers prospects, was limited to three hitless Cactus League at-bats before discomfort in his upper right arm prompted a shutdown.
"I'm bummed of course, but what can you do besides try to get healthy?" he said.
Nottingham expects to resume throwing on Saturday.
Diaz joins Puerto Rico for exhibitions
Twenty-year-old Brewers infield prospect Isan Diaz is getting a taste of the World Baseball Classic. Ranked fifth on MLBPipeline.com's Brewers prospect list, Diaz was loaned to Team Puerto Rico for exhibition games in Scottsdale on Wednesday and Thursday.

Braun debut coming
Brewers left fielder Ryan Braun tentatively expects to get his first Cactus League at-bats on Friday in a split-squad home game against the White Sox. Braun's delayed debut was by plan; he prefers a limited slate of at-bats to prepare for the season.
If Friday goes well, Braun said he may play again Saturday against the Padres. That game is also at Maryvale Baseball Park.
Last call
• Scooter Gennett's right wrist was still sore Wednesday so the Brewers pushed back his return to game action. He has not played since tweaking his wrist while making a play in the outfield on March 2, but has said the injury is minor.
• Registration is now open for the 19th annual 5K Famous Racing Sausages Run/Walk, to be held on Saturday, July 15 at 8 a.m. CT at Miller Park. Information is at brewers.com/5k.
