Condrey was summoned from the bullpen with the bases loaded in the 3rd inning after Brettt Myers, the starter, failed to get an out. Myers gave up 5 runs on 5 hits and 4 walks, in 2+ innings. His problems continue, and manager Charlie Manuel was visibly troubled when he went to the mound to give Myers the quick hook.
Pedro Feliz hit a grand slam for Philadelphia, whose lead in the National League East is down to one game over Florida after the Phillies' eighth loss in nine games.
Ian Kinsler went 3-for-4 and scored three times, the last on Josh Hamilton's sacrifice fly in the eighth that proved vital.
Kinsler led off the first with his 13th homer before adding two doubles, a walk and his 20th stolen base.
C.J. Wilson worked the ninth for his 17th save in 19 chances, after giving up a 437-foot homer to Jayson Werth on his first pitch. Josh Rupe (3-1) pitched 2 1-3 innings in relief.
The Phillies, the last of the other 29 current teams to ever visit Rangers Ballpark in Arlington, scored more runs in one inning than they had in any of their previous eight games. And that still wasn't enough.
After Philadelphia went up 5-1 with five runs in the third, Davis' two-run homer capped a five-run outburst by the Rangers in the bottom of the inning.
Davis, a 22-year-old slugger, started at first base a night after making his major league debut with a pinch-hit infield single at Houston. Along with his two-run homer, he made an impressive defensive play when he dove to his left to snag a short hopper and ran to the bag for the final out of the fifth.
Hamilton, who left Thursday night's game after getting hit by a pitch on the left hand in the first, had two RBIs to increase his majors-best total to 78.
Kinsler had a leadoff double in the third and came home after consecutive infield singles by Michael Young and Hamilton. Brett Myers was relieved after walking the next two batters, including David Murphy with the bases loaded.
Condrey coaxed a double play grounder from Marlon Byrd before the homer by Davis, a fifth-round draft pick two years ago who had 27 homers and 77 RBIs in 77 minor league games this season.
Philadelphia led 5-1 after its first hit of the game, the Feliz grand slam coming off left-hander Kason Gabbard. All of those runs were unearned because of an error by Gabbard when he didn't catch Werth's soft comeback liner.
Rollins had an RBI groundout before Pat Burrell was intentionally walked to load the bases, the third walk in the inning by Gabbard. Ryan Howard struck out before Feliz's fifth career slam.
After the Rangers responded, Gabbard didn't hold the lead long, allowing a leadoff homer to Chris Coste in the fourth that tied the game at 6-6.
Gabbard lasted only three more batters, leaving after consecutive singles before Rupe got Rollins to ground into an inning-ending double play on the first pitch the reliever threw.
Notes: Kinsler leads the AL with 104 hits and 69 runs scored. ...
The Phillies are 1-11 in the last 12 games started by Myers, who is 1-8 in that stretch.... Feliz's last grand slam was also in Texas, in Houston on May 16, 2006.
