The Nationals and infielder Sergio Alcántara have agreed to a minor league deal, reports Francys Romero of Beisbol FR. Even if he’s not dealt before the beginning of the upcoming season, he would be a trade candidate at the summer deadline. The top shortstop options behind him are Tsung-Che Chung, Nasim Nuñez and José Tena, who haven’t done much to impress in the big leagues thus far. Even if he plays well, he would be a midseason trade candidate like Abrams. Nuñez may be the heir apparent at second base.
