Texas second baseman Ian Kinsler, who is hitting .429 over his last 12 games, has been impressed with the recent additions.
"Things happen and you have to bring people up," Kinsler said. "Those were the kids that were in line and they're coming up here and pulling their weight. That's all you ask. The more opportunities they get, the more growth they'll have."
Hurley (1-1) allowed one run and five hits over 5 2/3 innings in his fourth big league start since being called up from the minors June 12. The 22-year-old struck out three and walked two.
"It has been a long wait," Hurley said. "I've played at every level the Rangers have. I feel I've worked hard enough to deserve the chance. So far, I think I've done pretty well with it."
Davis, who was called up from the minors Thursday, became the first Rangers player to homer in each of his first two starts, according to the Elias Sports Bureau. He hit a two-run shot in his first start Friday against Philadelphia.
"It's exciting," Texas manager Ron Washington said of the Hurley-Ramirez combination. "That's the second game that Max caught and he looked as good in that one as the first one. He and the pitcher were in synch."
Kinsler went 3-for-4 and extended his hitting streak to 12 games. Kinsler was 9-of-13 during the series against the Phillies in which the Rangers won two of three.
Philadelphia, which has a one-game lead over Florida in the National League East, has lost six consecutive series dating back to early June. This is most for the Phillies since dropping eight straight June 11-July 6, 2006.
"We've been losing games," Phillies manager Charlie Manuel said. "This is no time to feel sorry for yourself. You need to kick yourself in the behind and get back up."
Ryan Howard drove in the lone run for the Phillies, who mustered only five hits in losing for the 11th time in 14 games.
Philadelphia starter Jamie Moyer (7-6) gave up three runs in 5 2/3 innings. The 45-year-old lefty struck out six and walked four in a matchup against an opposing starting pitcher who was about half his age.

Philadelphia did not have a base hit the rest of the way. The Phillies, who had 15 runs in the first two games against the Rangers, has scored three runs or fewer in eight of their last 14 games.
"We're not swinging the bat well," Utley said. "We had a few opportunities, but just not enough."
The Rangers scored single runs in each of the first three innings off Moyer.
