Sherrill , the closer for Baltimore, was 0-1 with 20 saves and a 2.40 ERA, complemented by a 3.00 K/BB ratio through 41 1/3 innings of work.
Sherrill will likely be the primary setup man for Dodgers' closer Jonathan Broxton.
What this means for the Rockies is that there is 1 less LHP bullpen candidate available for trade. The Rockies will now turn their attention toward veteran Mark Hendrickson from the O's or perhaps to Toronto for LHP Scott Downs.
Bell, 23, is putting up a .296/.386/.497 line with the Chattanooga Lookouts, the Dodgers' AA affiliate.
Johnson, 22, made the jump to AA this season, and has a 1.69 ERA in 2 starts for the Lookouts.
