Pioneer North Division playoff preview
09/07/2007 12:45 PM ET
Great Falls vs. Helena
White Sox (50-23) vs. Brewers (47-28)
(Best-of-three series begins Saturday, Sept. 8)

It is only fitting that the two juggernauts of the Pioneer League's North Division finally get to slug -- and pitch -- it out for outright supremacy.

The Great Falls White Sox enter the postseason series with the league's best record, 50-23, and winners of nine of their last 10 games. But the first-half division-winning Helena Brewers are almost equally hot, 7-3 in their past 10 contest. Both teams are riding a seven-game win streak, but that will soon change for one club.

REGULAR-SEASON SERIES
In 15 meetings this season, the White Sox hold a narrow advantage over the Brewers, 9-6, thanks to a pair of sweeps, first in June and another in August. Great Falls outscored Helena in the regular-season series, 97-72. The Brewers won when the needed to, however, taking four of six meetings between the two clubs in July to emerge the first-half division winner -- two games ahead of the White Sox in the Pioneer League's North Division.

HISTORY LESSONS
Both clubs would love to generate some postseason success. Helena was in the hunt for the league title two years ago before the Brewers were handily dispatched by Orem, two games to none, in the 2005 championship series. Great Falls last saw postseason action in 2004, when its title hopes were quickly dashed in the opening round by Billings.

SERIES COULD TURN ON
The little things. Two games are in Helena; that could be enough of a factor to skew the outcome of the series. Great Falls holds a slim advantage in the offensive numbers this season, and the White Sox have the better pitching corps on paper. But the Brewers have seemingly been able to turn good play on and off this season. When they needed wins to secure the first-half division title, the Brewers found a way to collect them. In contrast, when the White Sox get cold, they get downright frigid. If both clubs bring their best play (which they seemingly will considering how the teams finished the regular season), this could be one of the most competitive postseason series in the Minors this year.

PREDICTION
At first glance, this series looks too close to call, and honestly the task didn't get any easier to do so with a second or third. Home-field advantage can play a huge role in the postseason, though, and two games are in Helena. Brewers in three.
