By Dan Ambrose: For the huge Vanes Martirosyan (32-0, 20 KO’s) fans out there, they might not be happy to learn that Top Rank has decided to move his fight against a badly overmatched Ryan Davis (24-9-3, 9 KO’s), which was previously scheduled for tomorrow night on the undercard of Julio Cesar Chavez Jr. vs. Andy Lee, to July 7th on the undercard of the Nonito Donaire vs. Jeffrey Mathebula super bantamweight unification bout.

The July 7th card needs a lot of beefing up after former WBA World lightweight champion Brandon Rios had to pull out of his scheduled fight against Maurcio Herrera due to an arm injury. The Donaire-Mathebula fight will be lucky if it draws any fans, because few people are interested in seeing Donaire face the little known Mathebula.

Boxing fans want to see Donaire face high quality fighters like WBA World super bantamweight champion Guillero Rigondeaux, Juan Manuel Lopez and Orlando Salido. The Mathebula-Donaire fight isn’t drawing any interest whatsoever, so Top Rank is probably going to need to make additional moves beyond just putting the Martirosyan-Davis mismatch on the card.

Earlier today, Top Rank put together a fight between former WBC/WBO middleweight champion Kelly Pavlik and Will Rosinsky for the card. However, Rosinksy is a complete unknown and Pavlik has lost a lot of fans, and he won’t be a big enough name to get many fans interested in his fight against the little known Rosinsky. If this was Sergio Martinez-Pavlik, then there wouldn’t be any problems because boxing fans would flock to see that fight. But not Pavlik-Rosinsky.

Martirosyan is taking a real go slow approach to working his way up to an eventual title shot by facing pretty much nothing but weak opponents while turning down big offers to face quality guys like Erislandy Lara and Alfredo Angulo.
