Here’s the latest from The Boston Globe’s Nick Cafardo in the newest edition of his Sunday notes column…

Zack Greinke may not find anything longer than a five-year contract this winter, according to a Major League source. Greinke turns 32 in October, so it’s understandable that teams would be wary about committing big money to a pitcher into his age-37 season, despite Greinke’s current outstanding numbers. It’s not as if Greinke will be suffering for money if he takes the expected step of opting out of his Dodgers contract, as an NL general manager calls a five-year, $150MM deal as “a good starting point.” That GM also predicts Greinke will ultimately remain with the Dodgers since they can afford his salary demands.

Last week, FOX Sports’ Ken Rosenthal reported on some bad feelings within Baltimore’s front office, stemming from owner Peter Angelos’ refusal to let Duquette pursue the Blue Jays president’s job without compensation.

Former Cubs manager Rick Renteria could re-emerge as a managerial candidate this winter, with Cafardo speculating that the Marlins or Tigers could be fits. Cafardo notes that Renteria was the finalist for the Tigers job before they hired Brad Ausmus, and that position could be open again if Ausmus is fired in the wake of Detroit’s disappointing season.

Joe Kelly has pitched very well over the last month but he may not have a spot in the Red Sox rotation next year, leading Cafardo to suggest that Kelly be converted into a closer if Koji Uehara can’t recover from his fractured wrist. Cafardo sees the 2016 Boston rotation as Clay Buchholz, Rick Porcello, Eduardo Rodriguez, Wade Miley and a yet-to-be-acquired ace, though I’d argue that Miley’s spot is far from set in stone. Plans could yet shift if the Sox move a starter in a trade, and Cafardo hears from an AL GM that Miley and Buchholz “would have value” if Boston shopped either starter. (Presumably the Sox wouldn’t move a promising and controllable arm like Rodriguez, and Porcello’s big contract greatly limits his trade value.)
