Remember JZ had Tommy John surgery 3 years ago. But I like the idea of pulling pitchers. Also, we don't know what the catchers are telling Davy Johnson about the pitchers sharpness, as the innings go on.
Honestly, JZ had already singled in a run earlier in the game - why not let him swing for laughs? Of course, the inning went well regardless, but I do understand the decision to bat Lombo. I just wish we were having this 'MLB-best' rotation get through the seventh inning more often.
