Jack Dorsey, CEO of Twitter.

When Twitter reports its second-quarter earnings after the bell on Tuesday, investors will see the results of one year with co-founder Jack Dorsey at the helm.

It's no coincidence that one day ahead of Twitter's highly scrutinized report, the company unveiled a new live-streaming sports deal that shows Twitter's new focus. The deal means Twitter will live stream weekly out-of-market games from Major League Baseball and the National Hockey league, as well as a first-of-its-kind nightly sports highlights program that will appear exclusively on Twitter.
