Sims gave up five runs in two-thirds of inning during Wednesday's 18-4 loss to the Brewers. He gave up one hit while walking four batters.
Sims was in a "get-work" outing, having last pitched Saturday and then five days prior to that. If the Reds beat the odds and actually have a save chance Thursday, there's a reasonable likelihood that Sims won't be available after throwing 34 pitches Wednesday.
