Eyre was 2-0 with a 7.15 ERA in 19 games over two stints with the Cubs. The 36-year-old was designated for assignment earlier this week.

"We were looking at him a couple years ago," Phillies assistant general manager Ruben Amaro Jr. said. "I think his recent ineffectiveness is probably because he wasn't used very much. We still think he has some bullets left in his arm."

The Phillies will make a roster move when Eyre arrives. It's likely left-hander J.A. Happ will be sent back to Triple-A Lehigh Valley.

Eyre didn't allow a run in his first 14 games (nine innings) and has held left-handed hitters to a .259 batting average.

In June, Eyre set a Cubs record with 33 consecutive scoreless appearances. The streak that started in August 2007 spanned 23 2-3 innings.

Eyre is in the final season of a three-year contract. He is 23-29 with a 4.42 ERA and four saves in 556 games with the Chicago White Sox, Toronto, San Francisco and the Cubs.

Schlitter, a 16th-round pick in 2007, was 4-3 with six saves and a 2.22 ERA in 34 games for Class A Clearwater. He will report to Class A Daytona Beach.
