He is like 100% correct, though. At the very least, Span batting lead off coupled with Bryce Harper batting 6th is dumb on every level. There were 6 guys in the lineup last night that get on base at a better clip than Span.
Werth RF, Harper CF, Rendon 3B, LaRoche 1B, Zimmerman LF, Ramos C, Desmond SS, Espinosa 2B is going to give you your most well rounded offensive/defensive lineup. If Espinosa's improved left handed approach continues to be productive, the upgrade of his defense vs. Zimmerman at 3rd will certainly compensate for anything you'd potentially lose with his bat vs. Span.
Not hitting Harper in the top 4 is ridiculous. This "he's a 5 hole guy or a 6 hole guy" old school garbage Matt Williams keeps believing is getting old. Get your best guys more AB's..it should really be obvious at this point.
Of course we're talking about a manager who insisted on running Nate McClouth out there everyday as his starting left fielder for ~40 games when he was hitting .080, so...not saying the bench was overflowing with capable alternatives, but .080?! His lineup construction and bullpen usage have been brutal all season.
