As of yesterday the current MLB attendance is 68% of full capacity.  
20% of all teams Attendance is down < 50%  
40% of all teams Attendance is down < 60%
Average Ticket Price According to Team Marketing Report = $26.74  
 
So crunching some numbers, if MLB lowered tickets prices 25% (average $20.06) and attendance rose to 90% they would earn the equivalent seat revenue compared to the 68%.  According to team marketing report, the average cost per family of 4 to go a ballgame is $196.89.  This value is determined by:
"The Fan Cost Index™ comprises the prices of two (2) adult average-price tickets, two (2) child average-price tickets, two (2) small draft beers, four (4) small soft drinks, four (4)
regular-size hot dogs, parking for one (1) car, two (2) game programs and two (2) least expensive, adult-size adjustable caps. Costs were determined by telephone calls with
representatives of the teams, venues and concessionaires."
 
So ask yourself, would you be more willing to take your family to a game if it was $50 less?
Look at the new Yankee stadium.  They are only at 85%?  For a new stadium, the Yankees?  This is amazing!  Enough is enough.
