Bats are obviously #1 in terms of blame, but I don't think the pen would be proud of their showing here either. Duffey had 2 outs, nobody on in the 7th, then gave up 3 straight singles to tie the game -- that's not just one mistake, that's a consistent failure to miss bats and put guys away. (And was perhaps bailed out of further damage by a baserunning blunder.) Same in the 9th with Romo -- 0-2 leadoff single, followed by another single. Yes, Polanco's error hurt, but in a quality relief appearance, there is more margin for error. The box score called them all "unearned" that inning, but Polanco's error alone shouldn't lead to 3 runs.
