With two outs in the bottom of the sixth and the Brewers trailing the Marlins by one, Mark Reynolds picked up a single. Ryan Braun began the play at second and should have scored easily, but Carlos Gomez was attempting to get to third base from first -- the single was to left field -- and was thrown out before Braun scored.
Here it is:
A challenge correctly upheld the ruling. The Brewers would go on to lose by one run, 2-1.
Whether blaming Gomez or the third-base coach -- and I'd go with Gomez as this ball is right in front of him -- this can't happen. The long-standing baserunning rule is to try and get to third base with less than two outs and to never, ever make the third out at third base. Once there are two outs, you don't push it because you're already in scoring position at second. The mistake ended up costing the Brewers a run and, ultimately, it could be argued, the game.
You have to credit Marlins left fielder Christian Yelich for the impressive awareness and execution on the throw, too, of course. Those pesky Marlins are now 20-7 at home.
