Phillies all-star leftfielder Domonic Brown, who was placed on the seven-day concussion disabled list on July 25, said that he thinks he will be ready for a rehab assignment beginning Monday.

"Nothing is definite, but it will probably be Monday," Brown said after Saturday's 5-4 loss in 12 innings to the Atlanta Braves.

When asked where it would be, he replied, "Hagerstown."

On Monday, the Phillies' low-A affiliate, the Lakewood BlueClaws, will play at Hagerstown, Md.

Brown has been sidelined since slamming his head on the warning track dirt when he dove but didn't come up with the ball in a 4-1 loss at St. Louis on July 23.

He is batting .271 with 24 home runs, 69 RBIs, and an .847 on-base-plusslugging percentage.

Improving Bastardo

Phillies lefthander Antonio Bastardo surrendered two walks and threw 25 pitches, but he escaped with a scoreless 10th inning during Saturday's loss to continue a recent swing upward.

Bastardo allowed just three earned runs in his last 20 innings (1.35 ERA).

Boos, then cheers

Closer Jonathan Papelbon was booed while entering the game in the ninth inning with the score 4-4. After striking out Justin Upton looking to complete a scoreless inning, Papelbon departed to cheers.

The boos stemmed from both Papelbon's blown save on Thursday against the San Francisco Giants and his comments about "not signing up for this," referring to the Phillies' being out of contention by the first week of August.

Streak continues

With a second-inning single, first baseman-leftfielder Darin Ruf extended his on-base streak to 31 games dating back to last year.

It is the longest current regular- season on-base streak in the majors and the longest for a Phillies player since Chase Utley reached safety in 33 straight games from Sept. 7, 2008 through April 22, 2009.

No excuses

Starting pitcher John Lannan lasted just 41/3 innings in Saturday's loss. He threw 77 pitches, 44 for strikes. The lefthander allowed four runs, two earned.

Lannan switched with Cliff Lee, who will pitch in Sunday night's game against the Braves. Lee has not pitched since July 21 because of a stiff neck.

Lannan didn't use the short rest as an excuse.

"No, not really," he said when asked if it had an impact. "I was falling behind hitters today and that kind of caused my pitch count to rise, and that isn't acceptable any time. But I felt good."
