The Orioles made a roster move that felt inevitable and another that came as a surprise prior to the start of their four-game set in Seattle.Struggling right-hander Dan Straily was designated for assignment Thursday while lefty starter John Means was placed on the 10-day injured list with a left shoulder strain. The Orioles activated outfielder Dwight Smith Jr. from the IL and recalled right-handed reliever Evan Phillips to take their spots on the 25-man roster.Means last pitched Sunday and told reporters in Seattle he’d felt some tightness in his shoulder at the end of the outing against Boston, but he downplayed the severity and didn’t undergo an MRI, describing it as a muscular issue. The rookie expects to come off the IL when eligible next Thursday, the day before the start of a three-game series against Cleveland. Means has easily been the most pleasant surprise in a very difficult season for the last-place Orioles, pitching to a 6-4 record and a 2.67 ERA in 70 2/3 innings.With Means originally scheduled to start Friday, the Orioles will now conduct a bullpen game against the Mariners.Straily was signed in early April to provide a veteran presence in the starting rotation, but the 30-year-old never found any semblance of footing with Baltimore and had allowed an incredible 22 home runs in just 47 2/3 innings. His intense struggles led to a demotion to the bullpen in late May, but Straily had allowed 13 earned runs and seven homers in his last two appearances covering only 3 2/3 innings to elevate his season ERA to 9.82, leading to his removal from the 40-man roster.Manager Brandon Hyde expressed hope that Straily would remain with the organization and try to get himself straightened out in the minor leagues. Entering 2019 with a career 4.23 ERA in seven major league seasons, Straily signed a one-year, $575,000 deal that included a $250,000 bonus if he were to be traded. He was released by Miami at the end of spring training and posted a 4.12 ERA with the Marlins last season.Right fielder and first baseman Trey Mancini was not in Thursday’s lineup after being hit by a pitch on the left elbow in the first inning of Wednesday’s loss in Oakland, but he is only dealing with a contusion and could return to action in the next day or two.
