The Dodgers made the expected (if not necessarily logical) roster move Friday night, activating reliever Jeff Weaver from the 15-day disabled list and optioning rookie starter John Ely back to Triple-A Albuquerque. The move comes one day after Ely delivered a superb start against the Brewers, allowing one earned run in 6 2/3 innings. Manager Joe Torre had said before and after Ely’s Thursday night start that he was likely to be demoted regardless of how he pitched because of roster concerns. — Ken Gurnick
