Nobody jumps out as a clear choice for leadoff without hurting another key batting order slot. I guess Santana's speed and the hope that he's played enough games, this year, that one might expect a groove-finding.
Had anyone said the argument for Arroyo as our lead off man been stated back in March, the poster might have been banned or institutionalized.
Marwin seems to be heating up, but I'd want a longer sample before giving the slot to him.
Vaz/Plawecki might be my second choice behind Christian.
