MILWAUKEE -- Right-hander Felipe Paulino, sidelined with a sore shoulder that recently shut down his rehab schedule, will be examined by team medical director David Lintner on Tuesday.

Paulino recently threw off the mound, and according to Astros assistant general manager Dave Gottfried, the right-hander didn't feel pain, "but he's still just not right."

Paulino has worked all season to recover from a pinched nerve in his upper right arm, but in his first Minor League rehab outing a couple of weeks ago, he left early with shoulder soreness unrelated to his prior injury. He has not appeared in a game since.

In other Minor League injury news, highly touted righty Brad James has missed more than a month with a lower back stress reaction. The club has hopes the Double-A hurler will pitch again before Corpus Christi's season ends on Sept. 1. James is 6-6 with a 4.55 ERA over 17 starts this year.

Veteran infielder Tomas Perez is done for the year with a hamstring injury, which is why he didn't receive a promotion to the big leagues when Kazuo Matsui went on the disabled list.

Righty Paul Estrada continues to make progress in his comeback attempt from a shoulder injury. He pitches every other day in relief for Double-A Corpus Christi, throwing one inning and approximately 25 pitches in each outing.

Estrada, who if healthy will compete for a spot in the Astros' bullpen next spring, has allowed one earned run over 4 2/3 innings, spanning five appearances.

"He feels good," Gottfried said. "Each outing gets a little better. He was tentative at first, but most guys are when they're coming back [from injury]. He feels good and that's positive. To finish the season that way gives him and us something to build off of."
