Fluke start is in he is doing worse than expected, or better?
Better. He has the second highest OPS on the Marlins, and a very Un-Encarnacion-like .362 OBP. That's also before tonight when he had a pair of RBI hits.
He's been hitting in the 5 spot for the past two games, and actually producing there.
It's remarkable.
It's way too early to draw any conclusions. Right now he's hitting .256 (11 for 43). If he was 10 for 43, that would be a .233 batting average. He's reached base 18 times in 50 plate appearances, for a .360 OBP. If he failed to reach base two more times (once a week), his OBP would be back down to .320. So honestly, I do not know.
