The American League's 3-0 victory Tuesday night on Fox earned a 6.9 rating and 12 share, up from a 6.8/12 in 2012.
Played at the Mets' Citi Field, the game's viewership got a boost from its trip to the big market of New York. The 11.3 rating there was up 16 percent from a year ago, when Kansas City hosted.
There was also a spike in viewers when Mariano Rivera made his final All-Star appearance, with the rating peaking at 7.6/13 right about that time.
Ratings represent the percentage of all households with televisions tuned into a program, while shares are the percentage watching among those homes with TVs in use at the time.
