PHILADELPHIA - John Mayberry Jr., normally an understudy, took his turn as a star Sunday afternoon for the Philadelphia Phillies.
Mayberry, pressed into service as the Phillies' center fielder after the usual starter, Ben Revere, broke a bone in his right foot Saturday, singled home the winning run with two outs in the bottom of the 10th inning as Philadelphia beat the Chicago White Sox 4-3.
It was the teams' third extra-inning game in two days and Philadelphia's second straight walkoff victory.
"We've been a resilient team," Mayberry said. "We've had guys go down in the past. There's always been someone to step in and fill that void. Hopefully the same thing happens with Ben."
Asked how much he welcomed the opportunity, Mayberry said, "I'm ready to play every day. (Manager Charlie Manuel) has proven in the past that if you play well and you're swinging the bat well, you'll be in the lineup. I don't expect that to change."
Revere, hitting .305 with 22 steals this season, was placed on the disabled list Sunday. He suffered his injury when he fouled a ball off his foot in the 11th (and final) inning of the first game of Saturday's double-header, which the White Sox won. Mayberry started the second game, a 13-inning Phillies victory, and homered.
Chase Utley led off the 10th Sunday by doubling off David Purcey (0-1). Jimmy Rollins was intentionally walked. Domonic Brown bounced softly to the mound, with the runners advancing to second and third, and Darin Ruf was also intentionally walked.
Ramon Troncoso replaced Purcey and struck out Delmon Young, but Mayberry grounded the first pitch he saw through the middle, vaulting the Phillies to 48-48 at the All-Star break. It is their first time at .500 since June 7.
"I was just looking for something out over the plate," Mayberry said, "and trying to put it in play someplace hard."
Antonio Bastardo (3-2) pitched a scoreless inning to earn the victory.
The White Sox, who once trailed 3-0, scored single runs in the seventh, eighth and ninth to tie it. The last was on Josh Phegley's RBI single off Philadelphia closer Jonathan Papelbon, who blew his fifth save in 25 opportunities.
"He might be getting a little spent this time of year," Manuel said. "The break's going to be real good for him."
Papelbon did not disagree, saying he is mentally fatigued.
"I think everybody on this team is going through it, mentally and physically," he said. "It's been a tough first half for us."
Cole Hamels pitched eight strong innings, and Brown, an All-Star, drove in two runs for the Phillies.
Hamels, working in 92-degree heat, yielded two runs and eight hits. He struck out seven while not walking a batter. Hamels also went 2-for-2 and drove in a run with a fourth-inning single.
Hamels, who surrendered Jeff Keppinger's RBI single in the seventh and Alejandro De Aza's solo homer in the eighth, gave way to Papelbon to start the ninth.
With one out, Dayan Viciedo singled. Pinch runner Blake Tekotte stole second and, with two outs, scored when Phegley grounded a single up the middle.
"We kept battling," White Sox manager Robin Ventura said. "We just couldn't get it done at the end."
White Sox starter Jose Quintana pitched six solid innings, and De Aza hit his 12th homer for Chicago, which fell to 37-54.
"The record stands for itself," Ventura said. "We'll just go home, try to clear our heads and get ready to go in the second half."
The Phillies, who were last at .500 when they were 31-31 on June 7, scored twice in the first against Quintana. With one out Utley walked and Rollins singled.
Brown, who on Tuesday will be part of his first All-Star Game, then blasted a 0-1 fastball to deep center for a two-run double.
Hamels' run-scoring single made it 3-0 in the fourth.
NOTES: Revere told reporters before Sunday's game the estimate he has been given is that he could miss six to eight weeks. General manager Ruben Amaro acknowledged that "it's going to take awhile" for Revere to recover, but will await the opinion of the specialist scheduled to evaluate Revere on Monday. Amaro did say the Phillies will be shopping for a center fielder, and that minor league 2B Cesar Hernandez was going to attempt to convert to the position. ... C Erik Kratz, out since June 9 with a left knee injury, was activated by the Phillies. ... Phegley, who started at catcher for Chicago, had to leave the game after taking a foul tip off his hand in the bottom of the ninth, but X-rays were negative. ... Chicago 2B Gordon Beckham did not play after bruising a quad in Saturday's second game.
