The Philadelphia Enquirer’s Matt Gelb says that the Phillies have confirmed the signing of left-handed pitcher Nate Robertson to a Minor League contract.

Earlier this month, B.J. Rains of FOXSportsMidWest.com said Robertson signed a Minor League deal with the St. Louis Cardinals. He went 2-1 with a 9.45 ERA with Triple-A Memphis this month in 6 games (3 starts) in 20 innings pitched.

Robertson, 32, was 6-7 with a 5.10 ERA in 18 appearances (17 starts) for the Marlins this season before he was released last month. He was acquired by the Marlins in a trade with the Detroit Tigers this spring. The Tigers would pay $9.6 million of the remaining $10 million on Robertson’s deal while the Marlins were only responsible for the MLB minimum.
