hit two-run homers off a sub-par Prior, offsetting a pair of long solo shots by
, as the red-hot Braves extended their winning streak to eight games with a 9-5 victory over the Cubs.
Atlanta's winning streak is its longest since a 15-game run in 2000. The Braves recorded their 60th victory, setting a franchise record for wins before the All-Star break.
In the bottom of the second inning, Prior (8-5) collided with Giles, the Braves' second baseman, who was trying to field a grounder hit by
Prior's left knee banged into the side of Giles' head and both players were motionless on the ground while receiving medical attention.
Giles was forced to leave the game and appeared woozy while being helped to the Braves' locker room. He suffered a mild concussion and was taken to a local hospital for observation.
"Giles was knocked out," Braves manager
said. "He doesn't remember the play happening, fielding the ball, who hit him or anything, but I think he's fine. He might get out of the hospital tonight."
Prior grabbed his right shoulder when he hit the turf, but walked off the field without any help and returned to the mound in the third inning. However, he was not sharp, allowing six runs and hits in a season-low 4 2/3 innings.
"I just saw him (Giles) out of the corner of my eye and I couldn't get out of the way," Prior said.
Prior hurt his shoulder when he landed awkwardly, but said he also got a charley horse and a shin bruise when his knee hit Giles.
"I went back and felt fine but the fourth and fifth, it started to get sore, my shoulder," Prior said. "I think I took the brunt of it on my shoulder, but my legs, my groin, were hurting."
It was the second time in just over a month a Cubs player was involved in a collision. On June 7, rookie first baseman

Despite giving up the homers to Sosa,
(5-5) recorded the win, allowing three runs and 11 hits in 7 1/3 innings with three walks and five strikeouts.
"My sinker was moving a bit and I was able to keep it down," he said. "I mixed in some curveballs and others, and I was lucky that Sammy came up with no one on base. He had my number today."
Sosa homered into the center field bushes in the fifth, then blasted his 516th career homer onto Waveland Avenue in the seventh. He needs five homers to tie
for 12th on the all-time list.
Hampton helped his cause with his first triple since July 28, 1999, a hit that drove in two runs in the eighth.
Castilla has eight RBI in the series after driving in four runs for the second straight day. He accounted for the Braves' first four runs with a two-run homer in the second and a two-run single in the fourth.
"I've just been trying to lay off the bad pitches and I've been working hard to try to and hit strikes," Castilla said.
Jones' homer made it 6-1 in the fifth and Prior left one batter later after walking
The Cubs closed within 6-3 on the homers by Sosa, but the Braves got back those runs on Hampton's triple in the eighth.
