Rangers working on deal with Luke Jackson

The Rangers are working on a deal to get Luke Jackson, the 45th overall pick in the draft, signed. Club officials said he's already been to Arlington for a physical.

Jim Callis at Baseball America reports Jackson has agreed to a signing bonus is $1.557 million, which is well above slot and will require the commissioner's office signing off on it before Monday's deadline for it to become official. The Rangers say they are still working on a deal.

Jackson, a right-hander, throws his fastball in the mid 90s and was considering going to the University of Miami. He pitched for Calvary Christian in Fort Lauderdale, Fla., and was 8-1 with 96 strikeouts and a 0.90 ERA in helping his team reach the Class 2A regional quarterfinals in 2010.

Callis writes that the recommended slot for Jackson, by the way, was $764,100.
