The Orioles added right-hander Jimmy Yacabonis to cover their bullpen after a 14-inning game that required nine innings of relief, with outfielder Colby Rasmus going on the 10-day disabled list with left hip soreness to make a roster spot.
Because 40-man roster players need to be optioned for 10 days past Opening Day to be recalled, Showalter said the Orioles needed an injury to add a pitcher. They would have found a way to do it either way, but Rasmus' surgically-repaired hip from 2016 has been bothering him for about a week. He also missed time in 2017 with the hip issue, which ultimately led to him leaving the Tampa Bay Rays midseason.
