ESPN.com's Sean McAdams has an article on 10 potential impact Minor League callups and he mentions Norfolk SS Anderson Hernandez as one of them:
ANDERSON HERNANDEZ, Mets: Obtained last winter from Detroit for Vance Wilson, Hernandez could be a candidate to take over at second base. Already, Hernandez has the defensive skills to the play at the big-league level. The Mets wanted to see more consistency at the plate and better contact, and Hernandez has shown both at Triple-A Norfolk. In 24 games in the International League, he has collected 17 RBI, compiled an on-base percentage of .411 and struck out just 10 times in his first 94 at-bats.
I have no problem giving Hernandez a shot at second base, assuming the Mets don't trade for Soriano.
