CHICAGO -- Michael Young singled home Roger Bernadina for the go-ahead run with a two-out single in the ninth as the Philadelphia Phillies topped the Chicago Cubs 6-5 on Friday.
Bernadina reached based by being hit by a Kevin Gregg pitch. He then stole second and came home with what proved to be the game-winning run on Young's base hit to right.
Right-hander B.J. Rosenberg (1-0), the Phillies fifth pitcher, got the win after working one inning and striking out two. Jonathan Papelbon pitched the ninth for his 23rd save.
Gregg (2-4) took the loss after working the ninth.
Cubs Hall of Famer Ryne Sandberg, got the win in his first visit to Wrigley Field as Phillies interim manager in the opener of a three-game series.
Working on a steamy afternoon with temperatures in the low 90s, Phillies starter Roy Halladay gave up five earned runs on seven hits through five innings and had no decision. He walked a pair, struck out one and hit a batter.
For Cubs starter Jeff Samardzija, the reigning National League co-player of the week, the outing was an improvement over his last game against the Phillies. On Aug. 8 he allowed nine runs on 11 hits in 3 1/3 innings.
On Friday, Samardzija ran into trouble in the sixth and seventh innings and departed after 6 2/3 innings. He gave up five earned runs on eight hits.
The Cubs grabbed the early lead as Anthony Rizzo lined a first-pitch solo home run to right center off Halladay in the first inning. Rizzo'a 21st homer of the season gave the Cubs a 1-0 lead.
The Cubs added two runs in the fourth. Nate Schierholtz led off with a homer to right field for his 20th of the season to make it 2-0.
Donnie Murphy then doubled and Brian Bogusevic followed with a walk. Both scored on Starlin Castro's two-out double to deep right for a 4-0 lead.
Bogusevic singled home Rizzo for a 5-0 lead in the fifth but was caught at second base trying to stretch his hit into a double.
Samardzija gave up four straight hits in the sixth and hit a batter as the Phillies scored four times.
Kevin Frandsen, pinch-hitting for Halladay in the sixth, tripled to deep center as Junior Lake misjudged his liner and the ball bounced to the wall. Frandsen came home on Michael Young's single to right. Jimmy Rollins followed with a base hit to center, and both came home on Chase Utley's triple.
Utley scored on Domonic Brown's grounder to second, narrowing the Phillies' deficit to 5-4.
Samardzija remained in the game and gave up a game-tying solo homer to Frandsen in the top of the seventh.
The Cubs threatened in the seventh with Schierholtz at first and Dioner Navarro at second with two out. Pinch hitter Darnell McDonald's singled into the right field corner, but Phillies' outfielder John Mayberry threw to catcher Carlos Ruiz to tag out Navarro at the plate
Sandberg, a 10-time All-Star and 1984 NL MVP, spent 15 Major League seasons with the Cubs and managed in the Chicago minor league system. He was passed over for the Cubs managerial job and joined the Phillies. He managed the Phillies' Triple-A Lehigh Valley team before joining Charlie Manuel's staff as third-base coach.
He was named Phillies' interim manager on Aug. 16. Sandberg succeeded Manuel, who had five NL East titles, two pennants and a World Series champion in nine Philadelphia seasons.
NOTES: The three-game series is the Phillies' lone trip to Wrigley Field this season. Philadelphia took two of three from Chicago earlier in August at Citizens Bank Ballpark. ... 1B Darin Ruf's nine homers in August are the most by a Phillies rookie since Ryan Howard hit 10 in September 2005. ... Schierholtz' fourth-inning homer gave him his first career 20-homer season. ... The Cubs are in the midst of a five-day stretch in which they will face four former Cy Young winners: Los Angeles' Zack Greinke and Clayton Kershaw, and Philadelphia's Halladay and Cliff Lee. ... Samardzija earned NL player of the week honors for games through Aug. 26 with back-to-back wins, including a complete game 11-1 victory over Washington.
