As they teeter between buyers and sellers, the third-place Phillies are possibly in the beginning of a roll that could help them get in position to make a run at the Braves and Nationals.
"No one is running away with it," general manager Ruben Amaro Jr. said of the National League East and NL Wild Card races. "No one is invincible."
The White Sox, despite taking two out of three from Detroit, are last in the American League Central and have been fielding calls for weeks.
While the Phillies have won six of their last eight contests, the White Sox came to Philadelphia struggling, as they have all season. Entering Saturday's day-night doubleheader -- the result of a rainout on Friday -- the White Sox have lost five of their last seven and are a paltry 6-20 in their last 26 road games.
The last time the White Sox struggled this bad was in 2007 -- the year of Chicago's last visit to Philadelphia and the only year in the Wild Card era the White Sox have finished worse than third place. The White Sox were swept by the Phillies that season, but they look to get off to a better start this time around behind left-handers John Danks and Hector Santiago.
Danks, who will pitch in the afternoon game against Jonathan Pettibone, has tossed three consecutive quality starts. He has worked at least seven innings in each, but he failed to earn a victory during that stretch.
Said Danks after his last start, a 3-1 loss to Tampa Bay: "I'm very confident with my stuff, and obviously the couple [starts] going into today were good. I was riding a pretty good high."
Santiago, who will face John Lannan in the nightcap, has split the season between the bullpen and rotation. He owns a 3.36 ERA in 11 starts, including a 3.67 mark in six outings since returning to the role on June 9. He has struck out 36 over 34 1/3 innings during that stretch.
Pettibone has allowed three or fewer runs in four consecutive outings, winning his last two starts. The rookie right-hander matched his season high with six strikeouts in both of those victories.
Lannan is coming off his strongest outing of the season, Monday against the Nationals. The lefty dominated his former team, giving up four hits over eight scoreless innings and inducing 12 groundouts.
"He was sharp," Nationals shortstop Ian Desmond said. "I didn't think he used his fastball as much as he used to. He was throwing a lot of changeups, a lot of sliders, a couple of cutters. I tip my hat to him."
If Pettibone and Lannan can help lift the Phillies to a pair of victories, that would guarantee the club no worse than a .500 record heading into the All-Star break.
"It'd be real good to win the series before we go into the break," Phillies manager Charlie Manuel said. "That's what we need to do, we need to start winning series, playing every day, winning series and all of a sudden, you look up and you're right there, you're sitting in a good position."
White Sox: Beckham keeps hitting
• Second baseman Gordon Beckham went 2-for-5 on Thursday and is hitting .400 with four doubles, two homers and eight RBIs in his last 17 games, nine of which have been multi-hit efforts. Beckham is hitting .375 since returning from the disabled list on June 3.
• With 430 home runs, Adam Dunn is one homer shy of tying Cal Ripken Jr. for 43rd place on the all-time list.

• First baseman Darin Ruf has a .714 slugging percentage through his first 47 games, with 17 of his hits going for extra bases. Ruf's mark is the ninth highest for any player in their first 47 career at-bats since 2000.
He's also 6-for-16 (.375) since being called up to replace the injured Ryan Howard on Saturday.
• Center fielder Ben Revere has hit safely in 13 of his last 14 games, hitting .441 with nine multi-hit efforts.
