Sources: Joe Wieland to make MLB debut Saturday

And so continues the graduation of talent out of the Padres top rated farm system as all signs are pointing at Joe Wieland making his big league debut on Saturday for the San Diego Padres.

How did we come to this conclusion?

First, there was this mysterious tweet:

Greatest day of my life! My dream has finally come true!!! God is great!!!!

— Joe Wieland (@JWieland108) April 11, 2012

Did Joe Wieland have a child? Did he get married? I don't think so. Therefore he must be talking about the dream of every boy and girl in the western hemisphere, many of those in Japan and Korea, and the kinda different ones in Australia. He's talking about making an appearance in the Big Leagues.

Shortly after that tweet, Corey Brock, Bob Scanlan and others all surmised that Joe would slide into the rotation on Saturday.

Here's what John Sickels had to say about Wieland last season.

And here's our brush with the future starter at Spring Training.

Baseball Prospectus (is that you Geoff?) calls Wieland an "excessive strike thrower". And scouts generally agree he'll rely on a plus curveball and a low (sometimes mid) 90s fastball to do his dastardly work.

This is the kind of stuff we have to get excited about Padres fans. Appearances by the youngies. Pretend like you're at a car show and you're looking at all the concepts. They may not be drivable right this moment, but revel in the fact that you're getting a glimpse into the future.

Dustin Moseley's MRI on Monday showed extensive damage to his right shoulder. He's currently on the 15 day disabled list.
