MILWAUKEE -- The postseason is still a week away, but the Milwaukee Brewers and Chicago Cubs can expect another afternoon of playoff-like intensity and atmosphere on Sunday when they wrap up a four-game showdown at Miller Park.

The first three games of this crucial four-game series between the National League Central-leading Cubs and the upstart Brewers have been riddled with drama: strong solid pitching, lockdown late-inning relief and last at-bat heroics as all three games went 10 innings and were decided by two runs or fewer.

"There's no difference between these three games and the games that are going to occur in the next month," said Cubs manager Joe Maddon, whose team has a 4 1/2-game lead over the Brewers in the NL Central. "They were absolutely that intense, well played on both sides, give both teams credit."
