CINCINNATI -- Left-hander J.A. Happ made his fifth rehab start Tuesday with Triple-A Lehigh Valley, but likely will get more work before he rejoins the Phillies.

Happ allowed six hits and four walks in just four innings Tuesday. He is 1-1 with a 6.98 ERA in five rehab starts.

Happ will throw a bullpen session on Thursday in Pittsburgh. The Phillies will evaluate him then. Happ has until July 7 to complete his rehabilitation, which means he can get one more start. If the Phillies decide he still is not ready to rejoin the club, they can apply for an extension to his rehab. If that fails, Happ has options remaining and could option him to the Minors.

Phils await reevaluations on Utley, Polanco

CINCINNATI -- The Phillies could have a better idea Thursday how long Chase Utley and Placido Polanco will be on the disabled list.

Utley, who is on the DL with a sprained right thumb, and Polanco, who is on the DL with inflammation in his left elbow, will be in New York on Thursday for further evaluations. Orthopedist Steven Cohen examined Polanco on Tuesday in Philadelphia. He will get a second opinion Thursday from orthopedist David Altchek.

Utley saw hand specialist Randall Culp on Wednesday in Philadelphia. He will get a second opinion Thursday from hand specialist Andrew Weiland.

The Phillies said on Tuesday that Utley and Polanco could miss anywhere from weeks to months.

Slider betrays Lidge on Tuesday

CINCINNATI -- Brad Lidge threw 23 pitches Tuesday against the Cincinnati Reds at Great American Ball Park, where he blew a three-run lead in the ninth inning.

He threw 17 sliders, and Reds first baseman Joey Votto, who crushed a three-run homer off Lidge to tie the game, appeared to be looking slider.

"Overall, it's been a big pitch for me my entire career," Lidge said of his slider. "For whatever reason, this year we've been using it too much. It kind of ruins the element of having a slider if you're always throwing it. It's a wakeup call to start using my fastball more. For whatever reason, we just keep going to it."
