Robertson signs Minor League deal

PHILADELPHIA -- The Phillies signed left-hander Nate Robertston to a Minor League contract. He will pitch Thursday for Triple-A Lehigh Valley.

Robertson went 6-8 with a 5.47 ERA in 19 starts this season with the Marlins.

Robertson threw 6 1/3 scoreless innings against the Phillies on April 18. After the Marlins released him, he made six appearances for Triple-A affiliate Memphis, which is St. Louis' affiliate. The lefty went 2-1 with a 9.45 ERA, but opted out of his contract because the Cardinals had not promoted him to the big leagues
