It wasn't as heavily promoted as Free Gold Weekends have been in the past, but Xbox Live's "Summer of Sports" event means in the United States, every holder of a Silver (free) Xbox Live account enjoys all the perks granted to Gold (paid) subscribers this weekend—online multiplayer, streaming Netflix, everything. Included with the weekend is free access to the MLB.tv app. Free access lasts until 9 a.m. PDT on Monday. [Xbox Live]
