What's this? A piece of news not relating to Pedro Martinez?

Phillies prospect Jason Knapp, a second round pick last season who is one of the hottest prospects in the Phillies system, was placed on the seven-day disabled list with shoulder fatigue. The righty, who turns 19 later next month, is 2-7 with a 4.01 ERA at Class A Lakewood, but has struck out 111 and walked just 39 in 85 1/3 innings. He last pitched on July 11, when he allowed six earned runs in just 2/3rds of an inning, prompting the club to shut him down.

Knapp is eligible to return this weekend, but will likely miss at least another week. The condition is not considered to be serious, but it is newsworthy considering the fact that the Phillies are hoping to make a play for Blue Jays righthander Roy Halladay. Toronto assistant general manager Tony LaCava has been scouting in Lakewood for the past week, while the Blue Jays have had scouts sprinkled throughout the Phillies' minor league system.

Knapp visited Phillies team doctor Michael Ciccotti in Philadelphia yesterday -- wonder if it was before or after the Martinez physical? -- and was given a "clean bill of health," according to assistant general manager Chuck Lamar.

Blueclaws catcher Travis D'Arnaud is also a rising prospect, although he has struggled at the plate at times this season.

Knapp, whose fastball reached into the upper 90's, is one of the three players speculated to be "untouchable" in any trade, although general manager Ruben Amaro Jr. has not said publicly whether Knapp falls into that designation.
