Seattle Mariners

The Baseball Team Which Dan ( Piper's Boyfriend ) Played On. In Give Me A Sign Phoebe Cast A Spell To Give Signs To Help Piper Pick Which She Would Rather Have As Her Boyfriend Dan Or Leo.But the spell actually provided signs to where Prue (who had been kidnapped) had been taken. While looking at demons that could have taken Prue, the Book of Shadows flipped itself to the Mariners entry. Phoebe noted that Mariners were good beings, and Piper misinterpreted it as a sign to pick Dan, as he played for the Seattle Mariners; it was actually a sign that Prue was being held at "Mariner's Bluff".
