Playoff races around baseball heated up yet again last week, with two divisions undergoing changes at the top of the standings and multiple teams still jockeying for position in each league's respective wild-card race.
Yet just when we thought we knew who the major players were going to be heading into the home stretch, the Washington Nationals seemingly emerged from nowhere and now pose a major threat to the three National League Central teams (Cincinnati, Pittsburgh and St. Louis) that were widely assumed to have three of the five playoff spots in the Senior Circuit all but locked up.
In the American League, injuries continue to decimate an already thin New York lineup, leaving the Bronx Bombers mere inches from falling out of contention altogether.
Let's take a look back at the biggest winners and losers from last week and what those results could mean for the rest of the season.
