PITTSBURGH — Zack Wheeler is pragmatic about his place in the baseball universe and the market for his services.

MLB’s non-waiver trade deadline is Tuesday at 4 p.m., and the Mets right-hander realizes he could easily be dealt before then. The Mets have received plenty of calls about his availability but are telling interested suitors, according to sources, it will take a top-10 prospect — and possibly more than one — to land Wheeler.

Such is the benefit of having a solid rotation option who is peaking in a thin market for starting pitchers.

“You might as well ask for a bunch if there is not much out there because you also have team control through next season,” Wheeler said Saturday. “I am not an elite guy, but I am decent for what is out there right now.”

The 28-year-old Wheeler will get the ball Sunday against the Pirates at PNC Park in one last showcase before July 31. Trades can still occur in August, but they become more difficult as a player must first clear waivers.

At first glance Wheeler’s 4-6 record with a 4.33 ERA is unremarkable, but it’s his recent improvement and sustained velocity on his fastball that has turned him into a commodity.

Over the past two months Wheeler has pitched to a 3.54 ERA while sustaining his 97 mph heat deep into games. It represents Wheeler’s most consistent stretch since arriving to the major leagues in 2013 in a career that was sidetracked for 2 ¹/₂ years by injuries.

“He is a hard guy to replace,” manager Mickey Callaway said. “That is why if they trade him, it will really have to be worth it, and I think they will do the right thing in that regard.”

From the Mets’ perspective, it would make little sense to head into 2019 built on pitching and trying to contend if Wheeler is not a component of the team. On the flip side, the Mets need to get younger and more athletic with their position players, and Wheeler is among the few players in the organization who can potentially bring such pieces through a trade.

Jacob deGrom and Noah Syndergaard both remain available, but the haul in prospects the Mets would have to receive makes it unlikely either pitcher will be dealt. Steven Matz is deemed another asset that would require a substantial return in a trade.

“Obviously I would rather stay here, but it’s a business,” Wheeler said. “I want to be here, but you [don’t always] get what you want.”

In the past week, Wheeler had watched Jeurys Familia and Asdrubal Cabrera, both of whom are headed to free agency after the season, leave in trades to the Athletics and Phillies, respectively.

Familia’s departure was especially difficult for Wheeler to absorb.

“Me and Familia sort of came up together, ever since we came over here, so it was tough because he is a good guy, a real genuine guy,” Wheeler said.

“When he asks you how your day is going, he actually cares about how your day is going, so that’s tough losing a guy like that. Cabby I think really did a lot for our big league team and he was a good guy, too.”

Wheeler insists he has not stopped to consider he might be pitching for the final time in a Mets uniform Sunday. In 2015, he was nearly traded twice but survived both scares. After his “fake” trade to the Brewers — along with Wilmer Flores — was scuttled because of concerns over Carlos Gomez’s medicals, Wheeler’s name had surfaced in a potential deal with the Reds for Jay Bruce. At the time, Wheeler, who was recovering from Tommy John surgery, called general manager Sandy Alderson and expressed his desire to remain in the organization.

This time around, Wheeler says he has not contacted the front office to say he wants to stay. That might be the product of realizing his voice probably won’t make a difference at this juncture in his career. For now, he is content to stay with the Mets and try to resurrect a franchise that could have a special starting rotation, if nothing else, in 2019.

“We’re all healthy for the most part, and when we get out there and take the ball, it’s tough to beat us,” Wheeler said. “We have got four guys in a row that don’t give other teams a break, so that is always tough on the other hitters.”
