One who would like to break into the win column this week is Moore, who fired a final-round 65 here in 2010 and finished a stroke short of Rose. He enters the tournament coming off another final-round charge last week in the Travelers Championship, in which he once again came in 1 shot off the winning number.
Last week's performance and his strong finish last year at Aronimink are a nice combination for the 28-year-old Moore, who has one career tour victory.
"That was one of my better rounds of the year, definitely, if not maybe the best," Moore said Wednesday of his 65. "This course is not easy, and you really have to do everything well. You have to control yourself all the way around the golf course. To do that on a Sunday when I was close and to at least put some pressure on [Rose], that was great."
Rose, 30, established a course record of 64 in the second round and parred the last eight holes to grab his second tour victory in three tournaments.
"The course brings ball-striking into the equation as much as anywhere we've played all year," Rose said. "You've got to hit the fairways - very difficult to play from the rough. I think you've got to be very patient and you've got to have great strategy. It's a golf course where it's not going to necessarily be 20 under par. I like that."
A total of 11 PGA Tour tournament winners from 2011 will be chasing the $1,116,000 first prize from the $6.2 million purse, including two-time champion Mark Wilson; former U.S. Open titlist Lucas Glover; and Nick Watney, at No. 15 the highest-ranked American in the field.
Aronimink favors good ball-strikers and good putters, and, statistically speaking, quite a few from each category are in the field.
