7 - Number of hat tricks the Washington Capitals have notched against the Ottawa Senators, the most they have against any single team (tied with Tampa Bay).
Four of those seven have come in Ottawa (where the two teams will play tonight), including a four-goal game for Alex Ovechkin, a three-goal game for Alexander Semin, and three- and four-goal games for Peter Bondra. The other three hatties were banked at home by Ovechkin, Bondra and Todd Krygier.
