Today is the first big day of the Division Series games, with four on the schedule.

First, at 12:00PM Eastern, the Tigers host the Athletics. The Tigers lead the series one game to none on the strength of Justin Verlander’s strong pitching and a home run from Alex Avila. Doug Fister starts for the Tigers and Tommy Milone goes for the As.

Update: Detroit wins 5 – 4 on a sac fly by Don Kelly in the bottom of the ninth.

The second game of the day is Game One between the Nationals and Cardinals in St. Louis at 3:00pm Eastern. The Nats will pitch 21-game winner Gio Gonzales while the Cardinals put Adam Wainwright on the hill.

Update: The Nationals win 3 – 2 on a 2-run pinch-hit single in the 8th inning by Tyler Moore.

The third game of the day begins at 6:00PM Eastern and features Game One between the Yankees at the Orioles in Baltimore. The Yankees’ starter will be CC Sabathia; the Orioles will pitch Jason Hammel. There’s rain forecast for the city, however, so this game may or may not be begun or completed.

Update: The game is in a rain delay at 7:00PM Eastern with no word yet on when or whether it will be played.

Update 2: The game is underway. It began at 8:40PM Eastern.

Finally, Game Two between the Giants and Reds is at 9:30PM Eastern from San Francisco. The Reds will put Bronson Arroyo on the hill while the Giants pitch Madison Bumgarner. One hopes they each pitch better than their teams’ relievers did in the ninth inning in Game One, when there were 3 wild pitches and a passed ball between the two teams. That didn’t keep the Reds from winning the game, however.

Update: The Giants – Reds game has begun. It’s being televised on TNT.
