Market Notes: Guerrero, Iwakuma, Latos, Prado, Cardinals, Ross

The Dodgers are having active discussions on utilityman Alex Guerrero, Ken Rosenthal of FOX Sports reports (Twitter links). Though Guerrero’s contract allows him to opt into free agency after the year if he’s dealt, Rosenthal notes that he’s expressed a willingness to work out a deal with a new team if he’s traded. Guerrero’s production has fallen back after a blistering early showing, and he’s lost playing time along the way, but he does offer relative youth and has shown good power. The 28-year-old has also dealt with a seemingly minor back issue of late. Los Angeles has several other similar utility options, as well as an overflowing stock of outfield pieces, so it’s certainly plausible to imagine that he’d have more value to another team.

Let’s take a look in at some other notable market developments as we continue to see significant activity in advance of Friday’s trade deadline:

• It’s not yet clear whether the Mariners will move pending free agent righty Hisashi Iwakuma, tweets Jon Morosi of FOX Sports. Seattle has, however, received interest from several clubs. Since a mediocre and injury-plagued start to the year, Iwakuma has turned in three consecutive solid outings and could be a nice mid-rotation piece for a contender.
• The Marlins are increasingly “confident” they’ll find a taker for starter Mat Latos, ESPN.com’s Jerry Crasnick reports on Twitter. Latos has pitched well of late and has appeal as a reasonably high-upside rental piece. According to the report, the market for his services is “coming into focus.”
• Marlins infielder/outfielder Martin Prado increasingly seems available, per Joel Sherman of the New York Post (Twitter links). An executive from another club says that the Fish appear to be “open to at least contemplate” a deal, which seemingly indicates slightly more availability than we heard yesterday (when Miami was said to be interested only for a sizable offer). Sherman notes that the Yankees and Mets could join the Royals with interest in Prado as a secondary option to Ben Zobrist (who is expected to be dealt in short order).
• The Cardinals are looking at possible bullpen additions to slot alongside the just-acquired Steve Cishek, Heyman tweets. St. Louis will hope to bring back righty Jordan Walden in the relatively near future, as he’s progressing through a rehab assignment, but the club has been active in recent years in adding pitching depth.
• Padres righty Tyson Ross remains a hotly-pursued name on the market, Jon Heyman of CBSSports.com reported yesterday. He’s drawn interest from teams like the Blue Jays, Astros, Dodgers, and Rangers, per the report. Expectations are that Ross would require a significant return, and Heyman notes that the team would likely prefer to move other pitching assets.
