They weren't content to be play the games in the daytime;
Yanks, they want to play with you all of the time;
The only time they feel all right is this time;
Sox, they want to play with you all of the time;
All the day and the all of the night;
All the day and the all of the night;
All the day and the all of the night!

The Yankees and Red Sox played a day/night and/or early dawn doubleheader in Fenway Friday and Saturday with the Yankees winning both games.

The Yankees won the first game, 12-4 in a brisk 3 hours and 55 minutes.

The teams broke for dinner and reconvened for the second game. The Yankees won that one too 14-11 in an amazing 4 hours and 45 minutes.

4:45 is a new record for a nine-inning game in the majors. And not by a little. The Yankees and Red Sox broke the old record of 4:27 set on October 5, 2001 when the Dodgers beat the Giants in San Francisco, 11-10. The length of the game is in part explained by the number next to the name "Bonds" in the home run section.

The previous record for an American League was 4:22 on September 5, 1997 when the Orioles beat the Yankees 13-9 at Yankee Stadium. Bernie Williams and Jorge Posada played in that game as well as the second game Saturday. Jesse Orosco pitched in the 1997 game for the Orioles and the 2001 Dodgers game. Cliff points out that Alex Cora played in the longest games (2001 for the Dodgers and 2006 for the Red Sox) and Derek Jeter played in the two longest AL games.

In addition, the record for the longest doubleheader (both games being nine innings) was shattered as well. The previous record was 7 hours, 39 minutes by the Rangers and White Sox at Comiskey Park. That took place on May 24, 1995. The White Sox won the first game 10-8 in 4:01 and Texas won the second game 13-6 in 3:38.

The Yankees and Red Sox took 8 hours and 40 minutes.

I haven't checked to see what the Elias Sports Bureau has ruled, but in the past, day/night doubleheaders weren't considered "doubleheaders." However, the Sporting News decided to consider day/night affairs as "doubleheaders."

Jon points out in the comments that Elias said it is was not a doubleheader. This is very much like Lewis Carroll. Elias is likely using the definition of "double header" (two words!) in Rule 2.00 "A DOUBLE HEADER is two regularly scheduled or rescheduled games, played in immediate succession."
