At least some folks think it to be the case:
Less than a week after the team slashed prices for many of its premium tickets, hundreds of premium New York Yankees tickets are turning up on StubHub, and speculation is rising that the team or intermediaries may have posted them.
While there is no direct proof that the team is involved – as a policy, StubHub does not disclose seller information – large quantities of premium seats are not turning up on other broker Web sites or exchanges, only on StubHub, which gives the impression that the tickets are not coming from multiple sources.
I don’t think there are any rules against this, though I suppose it’s possible that it may put the Yankees’ sideways with Ticketmaster, the team’s primary ticket agent. More than anything else it’s just kinda pathetic. The latest public evidence of a massive and arrongant miscalculation in demand on the part of the Yankees.
