ST. PETERSBURG -- On Monday, the Rangers announced the signings of Luke Jackson, the 45th overall pick in the 2010 First-Year Player Draft, and right-handed pitcher Justin Grimm, their fifth-rounder out of the University of Georgia. Jackson agreed to a $1.545 million bonus and Grimm, who turned 22 years old on Monday, agreed to a $825,000 bonus.

Jackson pitched at Calvary Christian Academy in Fort Lauderdale, Fla., where he was 8-1 with a 0.90 ERA while leading his high school to the Florida Class 2A Regional Quarterfinals. The Rangers worked hard at signing Jackson, who had a scholarship waiting for him at the University of Miami in case the Rangers missed Monday's deadline.

Grimm, considered a power pitcher with a fastball in the range of 90-96 mph and a sharp curveball according to Baseball America, was 3-7 with a 5.49 ERA his senior season with the Bulldogs after missing most of his junior year with a broken arm.

Both Grimm and Jackson will report to the Rangers' Rookie League affiliate in Arizona.
