Hernandez, now a reliever, pitched in five games and allowed one run in five innings for the Nationals.
This is Hernandez's second tenure with the organization. On Jan. 15, 2003, Hernandez was part of a three-team trade that sent him from the Yankees to the Expos. However, he never played a Major League game for the Expos. After pitching one Spring Training game, Hernandez went on the disabled list and then had rotator cuff surgery.
Hernandez, 40, is 90-65 with a 3.72 ERA in nine big league seasons. He is best known for his years with the Yankees, who he helped win three consecutive World Series titles from 1998-00. He also helped the White Sox win a World Series in '05. Hernandez's best season was in '99, when he went 19-7 with a 4.12 ERA for the Yanks.
As for Lombardozzi, who was selected by the Nationals in the 19th round of the 2008 First-Year Player Draft, he was hitting .293 with one home run and 38 RBI in 110 games for Potomac. He was also 20-for-30 in stolen-base attempts and scored 71 runs. In 107 games at second base this year, Lombardozzi committed only six errors.
