Hello External Hard Drive,
You can find the teams official broadcast schedule here.
Unfortunately, Cox doesn't have any control over which games the networks decide to air. The networks must abide by the MLB's broadcast rules (and blackout rules) for each market.
Blackout restrictions are based on the home team's television territory as defined by Major League Baseball [AND OTHER MAJOR SPORTS LEAGUES]. Blackouts are common in a number of out-of-market sports packages in order to protect local broadcast rights.
