There's always the Weaver method: better to give more innings to your best few guys than spread the load downward. Which holds true even if the top three aren't named Palmer, Cuellar, & McNally. (Btw how's that for the name of a crackerjack law firm?)
No details on how long or how much. Still, good for MASN to have some stability. Also:
”MLB viewership for the 2020 season was up dramatically across virtually every key demographic segment, with the most highly sought-after younger P18-34 (+53%), P18-49 (+31%) and P25-54 (+16%) demos leading the way. The growth RSNs are experiencing is impressive in their own right but when compared to overall broadcast television consumption, which is conversely down 24% year-over-year, the value of RSN’s is indisputable.”
