The Mets did end up paying a very small portion of Mo's contract. To put it in perspective the Angels ended up paying twice as much for Appier. But the money that the Mets were still on the hook for was deferred money to begin with. So yes techinically the Mets are still paying him and it works out to something like this:
There is some confusion because the Mets paid nothing in 02, 03, 04, because all of that money was picked up by insurance. So the Mets ended up paying ~14M for Mo but it hasn't been paid yet although it was accounted for in 02 so it's not a big deal. Cedeno's deferred money kicks in this year too. It's like 800K per year over the next three seasons.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
