Otero is likely to be the main right-handed set up option, John Hickey of the Bay Area News Group reports. Otero's main competition entering the spring appeared to be Tyler Clippard and Ryan Cook, but with the former likely to close until Sean Doolittle returns and the latter sent down to the minors, it seems to be his job to lose. The 30-year-old posted a 2.28 ERA in 72 appearances last season, mainly working in the seventh and eighth innings.
