Montgomery enticed a LH pinch hitter and then got him to hit a weak flare, and Chapman is the ideal guy to get K's when you desperately need them. Especially since Rondon didn't get used you can pull Chapman earlier if circumstances dictate too, but Chapman for 6 outs isn't really a problem. Except that Chapman for six outs with guys on base never works and Chapman himself hates it. Dammit Russell with bases loaded no outs, giving up 2 runs is pretty much a base expectation. Chapman not exceeding it isn't failure, but he was one pitch away regardless
