Last year he returned and batted .257 in 404 at-bats for high single-A Clearwater. Cartwright had 60 runs, 20 doubles, 8 triples, 5 home runs and 40 RBIs.
"It was tough coming back from the injury because there were times it would get sore and I would back off and get a little timid," Cartwright said. "Now it is good and I am off and running."
During the fall, Cartwright played for Great Britain in the World Baseball Classic qualifying round, hitting .455 (5 for 11) in three games as a shortstop.
"It was definitely one of my memorable moments in my baseball career," he said.
He has continued the success this season.
This is a critical season for Cartwright, who turns 26 in October.
"It's a big year for me because I got hurt and there was a setback and once again I have to prove what I can do and let the rest take care of itself," he said.
Cartwright is Reading's leadoff hitter and with shortstop Edgar Duran batting second, it gives the Fightin Phils two table-setters at the top of the order.
"Albert has done a tremendous job at the beginning of the lineup," Reading manager Dusty Wathan said. "He is a very aggressive guy."
While Wathan didn't see Cartwright play last year at Clearwater, he said it appears there are no after-effects from the injury.
"He is running really well, swinging the bat great and playing a tremendous second base," Wathan said.
Before this season, the Phillies had a talk with Cartwright about the ability to be more aggressive at the plate.
"He is very athletic and he has bat speed and the ingredients to hit and he had never quite put it together," said Joe Jordan, the Phillies director of player development. "To his credit in spring training our focus was for him to be aggressive, trust his ability and he has responded and has been a presence at the top of the lineup."
With Chase Utley a free agent after this season, second base could be a position the Phillies are looking to fill. At triple-A Lehigh Valley, Cesar Hernandez could be the heir apparent. Hernandez entered the weekend hitting .342 for the IronPigs.
