After Dean Kremer’s best start of the year, the Orioles informed the rookie right-hander they were optioning him to the minor leagues, using a pair of days off this week to shrink their rotation to four and carry an extra bullpen arm in the meantime.
With days off Monday and Thursday bookending their upcoming series in Miami, the Orioles won’t need a fifth starter until the following week’s home series against the New York Yankees, which lines up with the 10 days Kremer must spend at the alternate site in Bowie, their pseudo-Triple-A camp until that season begins next month.
