Boy, this season went by fast.

Seems like just yesterday that the Mariners were gearing up to take the league by storm with lights-out pitching and defense, and the Padres were preparing to field offers for Adrian Gonzalez. Those were the days.

Now, just three weeks away from game No. 162, much of the playoff picture looks clear. The Rays, Yankees, and Rangers all seem safe bets to play into October. The Twins’ lead, while far from secure, would likely withstand a White Sox winning streak, and barring collapse, the Reds should be able to maintain their edge over the scuffling Cardinals.

But there are still questions. The Giants and Padres are tied in the NL West with the Rockies just 1.5 games back. The Phillies have a game on the Braves in the NL East, and Atlanta, in turn, has a single-game lead over San Francisco and San Diego for the Wild Card—at most three of those teams can make the playoffs.

In this slideshow are this week’s top 10 series to watch, based on intrigue and potential magnitude of impact.

Here’s to another week of great baseball!
