Wednesday night in San Francisco, the Giants were no-hit by the Diamondbacks' Trevor Cahill through six innings. They did break through in the seventh, scoring a couple of runs, but by then the game was pretty much out of hand; Arizona led 6-2 going into the eighth inning.

In the top of the eighth, D'backs shortstop John McDonald led off with a single and was singled to second by Ryan Wheeler. The next hitter, rookie Adam Eaton, hit a ground ball to first baseman Brandon Belt, who threw to Pablo Sandoval at third in an attempt to get McDonald. That's when this happened:

Sandoval tagged McDonald; McDonald took exception, apparently, to how hard Sandoval tagged him. Sandoval took exception, apparently, to McDonald elbowing him in the chest after the tag. The two exchanged words; third-base umpire Greg Gibson held Sandoval back (no easy feat, as you might imagine), so there was no real fight, just a lot of cream-clad Giants and rust-colored Diamondbacks milling around third base until order was restored.

The D'backs eventually won the game 6-2 and crept to within 6½ games of the second wild-card spot; despite the loss, the Giants maintained their 4½-game lead in the NL West when the Dodgers lost to the Padres.
