Hamilton (hamstring) will begin a rehab assignment with Triple-A Nashville on Tuesday, Todd Rosiak of the Milwaukee Journal Sentinel reports.
Hamilton has missed the last two weeks of action with a left hamstring strain but has been cleared to test things out in games. If all goes well, the speedy infielder could return from the injured list Friday. Joey Ortiz has posted a 1.013 OPS with three home runs in 11 games since Hamilton was hurt, so Hamilton could operate in more of a reserve role when he returns if the Brewers want to play the hot hand at third base.
