It was a good night for the LA Kings – they won the Stanley Cup for the very first time. But for NBC, the Stanley Cup Game 6 (1.6/5) battle between the Kings and the New Jersey Devils at LA’s Staples Center was not so great. In Fast Nationals, which will probably be adjusted later, the 8 – 11 PM the live hockey game was down 20% from last year’s June 13 Game 6 between the Boston Bruins and the Vancouver Canucks in Boston. That makes this year’s Kings’ victory the lowest-rated game ender for the Stanley Cup since the Carolina Hurricanes beat the Edmonton Oilers in 2006.

Over on Fox, Gordon Ramsey had a winning night. Hell’s Kitchen (2.7.9) and MasterChef (2.6/7) were both up 13% over last week’s premiere. ABC’s 8 – 10 PM The Bachelorette (2.3/7) was up 5% from last week. The reality dating series was followed by a repeat of Castle (1.1/3)

With 6.58 million viewers, ABC won the night overall, but Fox took the night among adults 18-49. The network also had its highest rated Monday summer night since September 1, 2008.

CBS had a night of repeats with How I Met Your Mother (1.3/4), 2 Broke Girls (1.5/4), Two & A Half Men (1.5/4), Mike & Molly (1.4/4) and Hawaii Five-O (1.2/3)
