Report: Cuban-American businessman Mas serious contender to buy Marlins

Despite news of Jeb Bush joining Tagg Romney's group to bid against Derek Jeter in the sale of the Miami Marlins, it appears another individual has the upper hand.

A small group led by Cuban-American businessman and Miami resident Jorge Mas appears to have the most solid footing and deepest pockets among potential buyers, a source with direct knowledge told ESPN's Pedro Gomez.

Mas' group is said to be appealing to the club because it consists of less than a handful of venture capitalists, with Mas contributing a significant portion himself.

Citing Forbes, Gomez added that the group is expected to put forward a bid of $1.1 billion, which, according to Craig Davis of the Sun-Sentinel, would match the reported bid from the Bush-Romney group.

Jeter, meanwhile, recently told MLB he still hasn't raised enough funds to move forward with a proper bid, and was still seeking help from investors.

Mas, a graduate of the University of Miami, is the chairman and co-founder of MasTec, a $5-billion infrastructure, engineering, and construction corporation based in Coral Gables, Fla.
