That was down from an average of 15,483,000 for Houston's 5-3 win over the Dodgers previous year, a game that lasted 3:46.
Roberts obviously knew he'd have questions to answer regarding his decision and the Dodgers soul-crushing loss.
It was a night of themes that have recurred throughout the series.
The Dodgers were also closing in on victory at one point. The eight pitchers who followed Porcello did not give up an earned run over the next 12 1/3 innings, but the longer the game went on, the more it figured to have a huge impact on the Red Sox's pitching plans for the remaining two games at Dodger Stadium. That lead solidified with Steve Pearce hitting a three-run double. Dodgers manager Dave Roberts curiously turned to his exhausted bullpen with Hill rolling, and two batters after he exited, Moreland sent Scott Alexander's pitch into the back of the right-field bleachers with a 437-foot blast.
The Dodgers bullpen wasted a brilliant outing from Rich Hill, who allowed only one hit through 6.1 innings.
Then, a couple of themes the Dodgers preferred not to recur cropped up again. The Dodgers could become the first team to lose the World Series on their home field in back-to-back seasons since 1937.
The improbable surge all started with pinch-hitter Mitch Moreland's three-run homer in the seventh, shortly after Yasiel Puig's three-run homer in the sixth had put the Dodgers up 4-0. The Red Sox may well toss and turn thinking about one that got away.
Andrew Benintendi bats second and plays left field, with shortstop Xander Bogaerts dropping to fifth in the batting order.
That set the stage for Pearce in the eighth.
Feed the fans: The Dodgers actually reopened the concession stands around the time of the second singing of "Take Me Out To The Ball Game". Never before had a Series game gone more than 14 innings.
But the Dodgers, chasing their first World Series title in 30 years, needed a record 18 innings and a record seven hours 20 minutes to avoid being pushed into a 0-3 series hole from which only one team - the 2004 Red Sox in the American League Championship Series - have ever escaped.
Outspoken US leader Trump was less than impressed with what transpired, hitting out at Roberts after he removed Dodgers pitcher Rich Hill following 6.3 innings.
