"Fred is pissed every time the Yankees make a move," a source told Mike Puma of the New York Post. "And he always seems surprised."
At the root of Wilpon's consternation is the Yankees' willingness to take on huge contracts, an economic model he has long felt was "unsustainable" dating back to the team's decision to trade for Alex Rodriguez in 2004.
"[Wilpon] keeps saying the Yankees can't keep this model up," the source told Puma. "And they keep showing that they can."
"He cares a lot about the Yankees," another source added.
The Yankees may agree that their lavish spending isn't completely sustainable, however. The Yankees have been hit with the luxury tax for 15 straight seasons and "vow to get below next year's tax threshold of $197 million,'" according to Bob Nightengale of USA Today.
"My goal is still to be under the threshold," Yankees owner Hal Steinbrenner said last week. "Even with [Stanton] added. We're comfortably under the threshold with some more money to spend, whenever we deem we want to spend it."
The Mets payroll, meanwhile, is expected to sit around $135 million on Opening Day, according to Joel Sherman of the New York Post, a $20 million decrease from last season. That would put the Mets right around where the Houston Astros were last season, when the team had the 18th highest payroll in baseball at $134.1 million, per Nightengale.
The team's lone move this offseason is the signing of relief pitcher Anthony Swarzak for two years and $14 million.
