DISH Networks started a preview of MLB Network Strike Zone today. The free preview will run through Tuesday, April 23. MLB Network Strike Zone covers live games on Tuesdays and Fridays from 7 to 10 p.m. Eastern Time. During that time period the channel runs similar to NFL Red Zone, in which you are taken to various live games for updates and highlights. The network, available in HD on Channel 153, was recently added to DISH Network’s Multi-Sport package. MLB Network Strike Zone is also available on DIRECTV (Ch. 719), Time Warner Cable, BrightHouse and other providers (check your local listings).
