When Cristian Guzmán took over from Mike Morse in rightfield last night, I was astonished. Yes I was. Weren't we told Guzmán's arm wasn't up to playing at shortstop? It is actions like this that give sober men pause. Now it seems that according to an Adam Kilgore 'tweet', Desmond-of-the-two-errors is going to make way for Guzmán from time to time.
You could look at Fangraphs win probability chart and see that Josh Willingham was our batting star of the game. Or you could look at my own spreadsheet, with my own version of leveraged win value (which cumulatively appears in the sidebar), and see that Josh Willingham was the batting star of the game. This gives me confidence in my own system.
Finally, I'll just comment that despite Federal Baseball's headline, Marquis' outing was actually worse, by my measure, than Lannan's.
