Cafardo’s Latest: Beltran, Guerrero, Marquis, Soria

In today's column, Nick Cafardo of the Boston Globe discusses Buster Posey and Scott Cousins, examines what went wrong with Daisuke Matsuzaka, and lists 25 of baseball's most passionate people. Here are the other highlights from Cafardo's piece:

• A National League talent evaluator on Carlos Beltran: "A contending team is going to get Beltran at the trading deadline, and they’re going to be very happy with him. He can still hit. He can be an emotional guy, but put him in a place where it counts, and he’ll produce for you."
• At least a couple National League teams are eyeing Vladimir Guerrero as a potential trade deadline pickup. As Cafardo notes, the primary concern for NL clubs is how significant a defensive liability Guerrero would be.
• Jason Marquis could be had in a trade if the Nationals received young talent in return. Cafardo speculates that Josh Reddick would be enough to acquire Marquis, but the Red Sox appear to be content with Tim Wakefield at the back of their rotation for now.
• Joakim Soria's demotion from the closer's role doesn't make him any more available via trade. Cafardo spoke to Royals people who said the team still wasn't considering dealing Soria.
