Carlos Correa

The 2012 amateur draft kicks off soon, and yesterday we heard that the Astros are expected to select Stanford right-hander Mark Appel with the first overall pick. Here's the latest news on the event, starting with an update on the first overall selection…

• MLB.com's Jonathan Mayo has heard a lot of chatter about Puerto Rican shortstop Carlos Correa going first overall to the Astros (Twitter link). He feels it's posturing, however, and that Appel is still their selection.
• The Braves are likely to select a college player with their first round pick (No. 21), according to the sources of MLB.com's Mark Bowman (on Twitter). As Bowman notes, Mayo has Atlanta selecting Texas A&M outfielder Tyler Naquin.
• Though the Astros appear to have identified Appel as their top choice, they could move on to other options if the right-hander doesn’t show a willingness to sign at Houston’s price, Jon Heyman of CBSSports.com reports.
• WEEI.com's Alex Speier provided a breakdown of the new rules implemented by the new collective bargaining agreement, and also a primer on what the Red Sox may do.
• The Cardinals have five picks in the first and supplemental first round, and Rick Hummel of the St. Louis Post-Dispatch wrote about their possible plan of attack.
• The Phillies hope to land a college hitter who can reach the majors in short order with their first pick, writes David Murphy of The Philadelphia Daily News. They pick 40th overall after forfeiting their first rounder to sign Jonathan Papelbon.
• Nick Piecoro of The Arizona Republic tells us what to expect from the Diamondbacks on draft day. "The boring, standard answer is we’re going to pick the best player available," said scouting director Ray Montgomery.
• Nationals assistant general manager Roy Clark spoke to Adam Kilgore of The Washington Post about the difference between picking first overall (like the Nats did in 2009 and 2010) and picking in the middle of the first round (like they'll do this year).
