Here are some notes from the big apple's two big league clubs:

• The Mets are "in desperate need of clearing several spots" on their 40-man roster, and have "put out word to other teams that they are interested in moving non-core prospects" who would have to pass through waivers to be retained, writes Adam Rubin of ESPNNewYork.com. With the team likely in need of four roster vacancies to account for players who figure to be added to the 40-man before Opening Day, the Mets could look to move players such as Gonzalez Germen, Darin Gorski, Reese Havens, Juan Lagares, Cesar Puello, Elvin Ramirez, and Hansel Robles, according to Rubin. 
• The Blue Jays could be interested in the aforementioned Havens, tweets Andy Martino of the New York Daily News. Havens, a 25-year-old second baseman, has yet to see big league action and hit .215/.340/.351 over 390 Double-A plate appearances last year.
• After allowing him to reach free agency, the Brewers "didn't want to touch" Shaun Marcum this offseason due to injury concerns, tweets Martino. Marcum, now with the Mets, is looking unlikely to start the season in the rotation due to neck and shoulder issues, Anthony DiComo of MLB.com explains.
• The Yankees "will not receive credit on their 2014 luxury-tax payroll" for recently-acquired outfielder Vernon Wells, tweets FOX Sports' Ken Rosenthal. Instead, "the charge for him will simply be zero." Rosenthal had previously discussed the complicated background of the Yankees' attempt to maximize their ability to get under the luxury tax threshold in structuring the Wells deal. Wells is still due $42MM over the next two seasons as he plays out the end of his 7-year, $126MM deal. As Rosenthal explains, the Yankees will pay him $13.9MM of the remaining obligation, with only $2.4MM of that allocated to 2014 for purposes of luxury tax avoidance.
• Rosenthal discussed the financial impact to the Yanks for acquiring Wells, questioning whether the club might have been better served by instead inking Russell Martin this off-season. In particular, Rosenthal explained that Martin told New York that he would agree to a one-year deal for around $9-10MM before he agreed to terms with the Pirates on a two-year, $17MM contract.
• Discussing his contract, which he originally signed with the Blue Jays before it was famously assumed by the Angels, Vernon Wells acknowledged that "no one's worth that kind of money," tweets Andy McCullough of The Star-Ledger. Wells continued: "It’s what the market’s worth at that time … I caught the market at a good time."
• While commentators and fans seem skeptical of the Yankees' prospects for 2013, as well as their recent roster moves, GM Brian Cashman is resolute, writes McCullough (hat tip to River Ave. Blues). Cashman says that any notion of rebuilding is "just not part of our DNA," and rejects the notion that the team has been holding back on spending, though he acknowledges that he intends to "tread water until the guys come back." In terms of philosophy on long-term commitments, Cashman says he will not be "gun-shy," but nevertheless will be "more choosy" going forward. 
• Cashman also discussed the decision not to beat the Mets' offer for then-Twins hurler Johan Santana. Unlike current Yankees starter C.C. Sabathia, Cashman noted, Santana profiled as a "high-risk player going forward, health-wise."
