Scrabble and the Rookie
At this point, it might not make a whole lot of sense to talk about Sunday’s Game 1 of the Cardinals/Nationals NLDS, since Game 2 is already well underway at this writing. And if we’re going to talk about Sunday’s Game 1, it might not make a whole lot of sense to focus on just one single pitch. Game 1 featured several pitches, dozens of pitches, and each was important. But where many have discussed the decision to replace Mitchell Boggs with Marc Rzepczynski in the top of the eighth, I want to discuss the result of Rzepczynski’s first at-bat.
The controversy, if you want to call it that, is that the Nationals had two runners in scoring position with two out, and instead of letting Boggs face the left-handed Chad Tracy, Mike Matheny chose to have the left-handed Rzepczynski face the right-handed rookie Tyler Moore. Moore singled home two runs, turning a 2-1 deficit into a 3-2 lead, and the win-expectancy swing was about 47 percent. That single won Game 1 for the Nationals — it was a pretty important single.
