Forget all those unofficial, unsanctioned Matt Wieters(notes) prediction contests. Too sketchy if you ask me. This contest right here is the one you want.

Our rules are simple: In the comments section, offer your best guess at Wieters' fantasy line today. The contestant closest to the actual value of the showcase without going over will be declared the winner. Your prediction must be posted by 4:05 EDT.* First place earns you a spot in a midseason blog commenter league and the right to design the settings. (I'm still commishing, but you can declare the categories and playing style). Second place is a puma. 

Here are a few details to consider before revealing your forecast for Wieters' debut:

1) He went 4-for-4 in his final appearance at Triple-A Norfolk and he's hitting .368 over his last 10 games;

2) The O's are facing the 88-mph heat and .269 BABIP of Dontrelle Willis(notes) tonight, and the lefty says, "I'll just attack the strike zone";

3) Wieters is a switch-hitter who posted a 1.198 OPS versus left-handers last year, and he's delivered a 1.017 OPS against them this season; 

4) There's a chance of rain in Baltimore today, clearing in the evening.

My guess is that Wieters goes 1-for-2 with a pair of walks, two runs scored, one RBI and no steals. The hit will be a double, and it won't be cheap. And he'll have a sac fly. Please share your prediction below, after a few notes and links.

• Baseball America has posted their list of the top 200 prospects for the 2009 draft. Numbers 1-100 here; 101-200 here. 

• Clint Hurdle is about to open a cold-activated can of "You're fired," according to the Denver Post. 

• This is quite possibly the best thread in the history of message boards. There's obviously no penalty for piling on.

• Tom Glavine(notes) (shoulder) pitched five scoreless innings for Triple-A Gwinnett on Thursday. He's got another rehab start coming. Tommy Hanson(notes)? Still awesome: 60.2 IP, 1.48 ERA, 17 BB, 82 Ks.

• It sounds like Matt Capps(notes) and his owners have dodged a bullet. Nothing to fear there, except whatever you feared before.

• Good detail-rich read here from John Sickels on O's right-hander David Hernandez(notes). 

• Baltimore's Nolan Reimold(notes) has homered in three straight games, giving him five HRs in just 53 at-bats. He hit nine in 109 Triple-A at-bats, too. 

• Interesting stuff here on microfracture surgery from Jeff Stotts at RotoSynthesis; elsewhere, Chris Liss posted the results of the RotoWire NFL mock draft.

• Fake Teams poses an interesting question: Which shortstops can reasonably be started ahead of Ben Zobrist(notes) right now?

I'm off to conduct high level Billingsley research at Wrigley. If you're anywhere near a wireless network around 7:00 EDT tonight, please consider joining Scott for a very special Wieters Day extravaganza. We're going to play this one just like Opening Day, with a few updates throughout the evening.

*OK, we might consider entries posted after 4:05, but prior to the opening pitch. Depends on the quality of the early predictions. Someone must have nailed it.
