MLB Trade Rumors

The rise of Pirates call-up Gregory Polanco from a virtually unknown international signee to a top prospect has been quite rare in recent history, writes Alex Speier in an ESPN Insider piece. Slowly but surely, the 22-year-old tightened his skills to match his raw tools, and his now-obvious upside emerged.

Here’s more from the National League:

• While Polanco is undoubtedly an exciting addition for the Pirates, the team should nevertheless be prepared to sell over the summer, opines Paul Swydan of ESPN.com (Insider link). Russell Martin and Francisco Liriano are among the pieces that the team could consider moving, he says. Meanwhile, the Mets and Padres are other NL clubs that Swydan says should look to move pieces.
• While Swydan does not discuss their situation, the Phillies also seem like possible sellers, though it is hard to know the club’s thinking. Corey Seidman of CSNPhilly.com discusses the trade-worthiness of several of the team’s possible deadline chips.
• The Mets‘ struggles this year are bad enough that they have shifted the team’s seemingly promising trajectory, writes Kevin Kernan of the New York Post. The team’s key cog, third baseman David Wright, says that he remains committed to the Mets and has no desire to be dealt. (Of course, that seems a rather unlikely outcome regardless.) “I knew that when I signed my extension, I knew that things were not going to be easy,” he said. “If I wanted the easy way out, I would have signed somewhere else. The challenge of it, the loyalty to the organization, the direction I think we’re going, yes, we’ve gone through some rough stretches … but that is the process.”
• The Rockies, who dropped their ninth of ten games tonight, are now dealing with another spate of bad injury news. In addition to placing recent top prospect call-up Eddie Butler on the 15-day DL after his first big league start, the team learned today that it will be without two key veterans for some time. Star outfielder Carlos Gonzalez will undergo exploratory surgery on the left index finger that has bothered him this year, reports Nick Groke of the Denver Post (via Twitter). And right fielder Michael Cuddyer has suffered a fracture of the glenoid socket in his right shoulder, which will keep him out for at least six to eight weeks, as Cody Ulm of MLB.com reports on Twitter. Now well off the pace in the NL West, the Rockies would need a quick turnaround to position themselves as contenders as the trade deadline approaches.
• In need of arms, the Rockies will call up 23-year-old lefty Tyler Matzek to start on Wednesday against the Braves, Patrick Saunders of the Denver Post reports on Twitter. Once a top-25 prospect league-wide and the 11th overall choice in the 2009 draft, Matzek has climbed through the minors even as his prospect shine has dimmed somewhat. After opening the year rated 12th among Colorado prospects by Baseball America, which noted that struggles with consistency and command could push him to the bullpen, Matzek has worked to a 4.05 ERA in his first 66 2/3 innings at the Triple-A level. More importantly, perhaps, he has worked to a career-best 4.2 BB/9 at Colorado Springs while also racking up 8.2 K/9.
• ESPN.com’s Keith Law has posted his round-up (Insider link) of the draft haul from National League clubs. He says that the Diamondbacks brought back an impressive haul across the board, and casts some doubt on some of the Cubs‘ early-round selections while noting that the team went after high-upside arms further down.
