I am afraid that it is still not possible. Including today's game they have an attendance of 1,502,677 + 45,962 in 40 games - http://espn.go.com/mlb/attendance . So if they drew sell outs of 49,282 for the remaining 41 games then they would have a total attendance of 1,502,677 + 45,962 + (41)*49,282 = 3,569,201
