The Cincinnati Reds have placed Bronson Arroyo on the 10-day disabled list with a strained right shoulder, one day after the 40-year-old right-hander said there is a possibility his career might be over. Cincinnati also put shortstop Zack Cozart on the 10-day DL Monday due to a strained right quadriceps. Arroyo gave up five runs and seven hits in just three innings Sunday as the Reds lost 8-7 to the Los Angeles Dodgers.
