The Oakland Athletics optioned right-handed reliever Dan Otero to the Triple-A Nashville Sounds and transferred outfielder Coco Crisp to the 60-day disabled list in order to add switch-pitcher Pat Venditte to the active roster before Friday's game against the Boston Red Sox. Otero had two option years remaining coming into the season, and was well under the five years service time required to refuse such an assignment. Otero used up an option year in 2012, but his 2014 assignment does not count against him as it only lasted three days.
Otero has found himself struggling this year, especially with giving up the long ball. After starting his major league career conceding no home runs in his first 63⅔ innings and just four home runs in 2014 over 86⅔ innings, Otero has since allowed four home runs this season in just 24⅓ innings. He has a career-high 6.29 ERA after completing a 2.01 ERA with Oakland in 2013–14.
Coco Crisp received an epidural in his neck last Monday. He is not expected to be available until after the mid-July All-Star Break.
