The 19-year-old Crawford moved up 31 spots on Keith Law's midseason prospect rankings to 15th-best league-wide.
Crawford, the youngest position player in the Futures Game this past Sunday at Target Field in Minnesota, has hit .286 with a .380 on-base percentage in 82 games this season at Class A Lakewood and High A Clearwater.
With the Threshers, Crawford started slowly but has a 10-game hit streak and has already homered four times in 97 plate appearances.
In 135 minor-league games, Crawford has a .294 batting average with an eye-popping .390 OBP. He's walked nearly as much as he's struck out, and defensively he's been smooth and impressive.
The 2013 first-round pick may be just two years away from the majors. There isn't a lot of impact young talent in the Phillies' farm system, but Crawford could make up for the lack of depth if he turns into the star that so many scouts believe he can be.
"He's shown an excellent approach at the plate, especially pitch recognition, even against lefties," Law writes of Crawford, "and his glove isn't that far away from being major-league ready."
Good news for the Phils, because Jimmy Rollins is not signed past 2015. In 35 plate appearances, Rollins' $11 million option for next season will trigger. After that, he's set to become a free agent.
