The AP story refers to a percentage of the potential viewing audience, whereas MLB’s story mentions absolute numbers of people (rather than audience share). Both statements could be true, in their respective ways.

Entertainment Weekly informs us that though the absolute viewership was up, it was not up much from last year. This puts the increase in context and seems credible.

The NYT says there was a more viewers than over the past 7 years, but does not say how much more, allowing Entertainment Weekly to honestly tell us, not much higher.

All the statements sound plausibly consistent.
