ST. LOUIS -- The Brewers have added another Braun to their system.

Steve Braun, an infielder and the younger brother of Brewers All-Star Ryan Braun, signed with the team as an undrafted free agent a few days ago, passed a physical on Monday in Phoenix and was scheduled to travel to Helena, Mont., by the end of the week to begin his career with the Brewers' advanced Rookie League affiliate.

"Who knows what's going to happen, but if it all works out and we got to play together one day at this level, it would be pretty cool," said Ryan Braun, who is exactly 18 months older than his 23-year-old brother. "Just both of us being in the same professional organization is special. Not too many brothers ever have an opportunity to do that."

In 49 games with the University of Maryland Terrapins this season, Steve Braun batted .276 with two home runs, 23 RBIs and a team-high nine stolen bases. After he went undrafted, Ryan Braun lobbied Brewers officials to give him a shot.

Steve Braun played shortstop and second base at Maryland. Helena was short of infielders, Brewers general manager Doug Melvin said.

"He's really good defensively, and he can run," Ryan Braun said. "He's a good athlete. He just never really hit, which is the reason he didn't get drafted. The ability has always been there, and he always works hard. It's just a matter of putting it all together."

Also on Tuesday, the Brewers announced they had come to terms with right-hander Blake Billings, a prep pitcher selected in the 19th round of the First-Year Player Draft whose deal was first mentioned on the "Brew Crew Ball" blog last week.

The team also signed undrafted right-hander Bobby McEwen from Gonzaga University.

Milwaukee has now signed 34 of its 54 Draft picks including 25 of its first 26 picks. Their first-round pick, catcher Brett Lawrie, is playing for Team Canada in the run-up to next month's Olympic Summer Games. He remains unsigned, but indications from both sides are that a deal will be struck before the Aug. 15 deadline to sign Draft picks.
