Tonight they're stomach-turning points.

3) Nick Punto's second inning line out: +.068 WPA
In between events #1 and 2, Jerry Hairston Jr made a great defensive play to rob Punto of a single and likely RBIs.
4) Jerry Hairston Jr's third inning strikeout: -.061 WPA
The Brewers had runners on first and third with one out in the third after Zack Greinke and Corey Hart singled, but Hairston struck out swinging and Ryan Braun popped out to end the inning.

One batter before Hairston's strikeout, Hart was the second half of back-to-back singles to put two men on with one out in the inning. Neither scored.
