Delgado now aware of the day/night splits.

Newsday's David Lennon picked up on the story recently (but not first) published by me about Carlos Delgado's huge day/night splits.

Sounds like not much will happen unless Delgado sees a causal link between the two. I certainly can't see the harm in him getting his eyes getting checked out by a professional. It could be the difference between retirement and an extended career as a DH in the AL next year.

I think the first person who wrote a pretty substantive article about this issue was Alex Britell of the New York Sun. His article, which I found after writing mine, was published on 5/19/08. At that point in time, the sample size for Delgado's splits weren't large enough, although it was certainly something worth noting.

Now that a half-season has been played and the day/night split trends continued, Britell's article proved to be quite telling.

One thing that I think got lost in the translation, from here to MetsBlog to Newsday, is that 3 of the 4 HRs Delgado has hit in night game this season, were hit in natural daylight. So while they are attributed as "night game HRs," they were really hit under conditions of natural light, even if the sun wasn't shining bright in the sky.
