I would sell it. Doubt Topps will replace it. There are people dieing to get his card no matter the condition. You can sell it for less than a perfect center but you will still get some bucks for it.
T-30 minutes till he pitches against the Tribe,..lots of tickets sold.The weather is very humid and hot so he's going to get heated up quick.The Tribe bats have been soft(remember the near perfect game 2 weeks ago),.
Sent about 12 2010 Bowman Chromes (including Strasburg) back last week and received those exact same 12 cards back from Topps today,all with well centered backs. Hope they hook you up like they did me.
