Chase Utley came off the disabled list on Friday and scouts for the Yankees and Giants were in attendance to watch the Phillies play.
Both teams have suffered injuries to their infield, but it hasn't been confirmed that they were scouting Utley.
Recently, scouts for the Red Sox and Tigers have attended Phillies games. Both teams have relief issues, linking them to Jonathan Papelbon.
Utley, 34, will be a free agent at season's end. If the Phillies don't make that run in the next six weeks, he could be attractive to a contender.
