Strop allowed multiple runs in his last two outings and owned a 6.11 ERA before going on the DL with a strained lower back. Control has been a struggle for him throughout the season — he has 14 walks and 17 strikeouts over 17 2/3 innings.
Chris Tillman has been put on the 15-day disabled list with left abdominal strain retroactive to March 22. He will be able to come off the DL on April 6 and pitch the Orioles' fifth game of the season against the Minnesota Twins.
As the competition for the Orioles' fifth rotation spot begins to heat up, right-hander Jake Arrieta made his case Saturday afternoon, throwing 4 2/3 shutout innings in a 3-1 win over the Toronto Blue Jays at Florida Auto Exchange Stadium.
SOrioles second baseman Brian Roberts hit a par of doubles and scored two runs, while left fielder Nate McLouth added a two-out, pinch-hit double in the fourth inning to give the Orioles a 5-1 win over the Yankees at Ed Smith Stadium.
Trayvon Robinson suited up for the first time as an Oriole on Saturday and took part in the first official full-squad workout, but the outfielder had hoped to be in camp a lot earlier after being acquired in the November deal that sent infielder Robert Andino to the Seattle Mariners.
