Phillies Sign Nate Robertson

The Phillies signed Nate Robertson to a minor league deal, according to Matt Gelb of the Philadelphia Inquirer (on Twitter). The Cardinals signed the left-hander earlier in the month, after the Marlins released him.

The Phillies will assign Robertson to Triple A, the same level at which he struggled in the Cardinals system. The 32-year-old posted a 9.45 ERA in 20 innings at Triple A Memphis, allowing 32 hits and six walks along the way. The results weren't much better at the major league level for Robertson this year. He posted a 5.47 ERA with 5.5 K/9 and 3.6 BB/9 for the Marlins.
