The Yankees were happy to get 4.2 solid innings from Randy Vásquez in his MLB debut last night, but since they’ll get Domingo Germán back from suspension on Monday in Seattle, they wanted to get a fresh arm to take Vásquez’s roster spot. So the rookie was demoted after the game, and this morning, New York called up a new rookie to take his spot: lefty Matt Krook.
Added to the 40-man roster back in November, Krook has been a candidate in the early offing to make an MLB appearance at some point. This will be his first time in the majors though.
