Warren earned the first save of his career Sunday by throwing a scoreless ninth inning with one strikeout and one hit allowed against Atlanta.
Tony Santillan, who earned the save for Cincinnati on Opening Day, got the final out of the seventh inning before pitching the eighth. Sunday's appearance was the first of the regular season for Warren, who emerged last year to become one of manager David Bell's most trusted bullpen options. This looks like it may be a full-blown closer committee, with Warren and Santillan at its head, at least until Lucas Sims (elbow) returns.
