The Giants have used four pitchers. The Reds have used two pitchers. So how do the Giants have a two-run lead over the Reds in the bottom of the fifth inning? It's like Joaquin Andujar said: youneverknow.
With Mat Latos pressed into duty in Game 1 because of Johnny Cueto's first-inning injury, Mike Leake was pressed into starting duties for the Reds in Game 4. But Angel Pagan led off the game with a home run, and Gregor Blanco hit a two-run shot off Leake in the second inning. That made it 3-1, but Ryan Ludwick narrowed the gap with a leadoff homer in the bottom of the third.
Leake couldn't survive the fifth inning, though. Joaquin Arias led off with a double to left, and came around to score when Pagan doubled to right center. After Marco Scutaro sacrificed Pagan to third, Dusty Baker replaced Leake with Sam Lecure. His first pitch to Pablo Sandoval was hit plenty far enough into center field for a sacrifice fly, with Pagan sprinting home.
LeCure retired Buster Posey to end the half-inning, but the Giants are now ahead of the Reds, 5-2.
