What Is Jose Valverde's Real Birthday?

My old (blog) buddy Tim Dierkes writes mlb trade rumors. I was looking through it the other day at an entry discussing Jose Valverde's impending free agency and noticed that he stated that Jose is 32. I thought - Tim mis-typed, I'd better send him a note. You see, Jose's birthday is July 24, which is Barry Lamar Bonds and Barry Lamar Dog's birthday, so I PARTICULARLY remembered that, and I also remembered the talk about him turning 30 this July. (I also noted that it was more than interesting that TWO guys on my team had that July 24 birthday - Jason "ofer" Smith is the other guy.) But, surprise, surprise, even though Jose's birthday was listed as July 24, 1979 in last year's media guide and on the Opening Day lineup card, it is now listed as April 24, 1978 on the Astros website, Yahoo and Espn. Not surprisingly, it is still listed as July 24, 1979 on Baseball-reference.com and Baseball Cube. Is this a mistake? Or is Jose yet another person who, uh, had an, um, er, birth certificate whose numbers were, uh, um, let's say, illegible? This isn't my imagination or me mis-remembering. According to the Chron, Valverde was 28 in December of 07 when we obtained him from the Diamondbacks. In fact, almost every Chron story which lists Valverde's age corresponds to him having a July 79 birthday. Might could be that the extra 15 months may affect Valverde's value as far as long term contracts go, even though he is still obviously a top-notch closer. I guess that after the whoop-to-doo over Miggy and the 2 years, the Astros are, if this isn't a mistake, trying to sneak this one under the radar. And they woulda gotten away with it, too, iffn it wasn't for them meddling bloggers.
