NEW YORK -- The Phillies released righthander Jason Marquis, who was attempting to make a comeback to the majors while pitching at Triple-A Lehigh Valley. Marquis underwent Tommy John surgery in July of 2013. He signed a minor league contract with the Phillies in June

The 36-year-old Marquis, who made 309 career starts in the majors, was 3-1 with a 4.63 ERA in 46 2/3 innings for the IronPigs.

Marquis was slowed for a few weeks with an oblique injury. He last pitched for the IronPigs on Friday in a 6-5 win over Scranton. The righthander allowed eight hits and five earned runs in six innings to earn the win.

Marquis was one experiment that didn't work, but so far the signing of Jerome Williams has proven beneficial.

After Saturday's 7-2 win over the New York Mets, Williams is now 3-0 with a 2.02 ERA in four starts with the Phillies.
