Los Angeles Angels pitcher Kenny Rosenberg will be on the mound Monday night as he takes on the Baltimore Orioles in what marks his first start at the MLB level this season. The southpaw has made a pair of long relief appearances for the Halos this season but has worked as a starter at the Triple-A level. Rosenburg has made 20 starts for Triple-A Salt Lake, working to a 4.95 ERA across an even 100 innings of work. Monday night will mark the 28-year-old's second career start and sixth appearance in the big leagues while he sports a 5.09 ERA with seven strikeouts and another seven walks across seven innings of work in his brief MLB tenure to this point. He'll battle an Orioles offense that is tied for ninth with a .330 wOBA versus left-handed pitching this season.
