1st-round pick Tyler Kolek agrees to terms for $6 million

Tyler Kolek is about to become one of the wealthiest 18-year-olds -- if not THE wealthiest resident of any age -- in the Texas town of Shepherd. The hard-throwing right-hander, whom the Marlins selected with the second overall pick in last week's amateur draft, has agreed to terms on a $6 million bonus, sources have confirmed.

The deal is pending a physical.

The Marlins surprised some by taking Kolek over North Carolina State lefty Carlos Rodon, who went to the White Sox on the next pick. But the Marlins found Kolek and his triple-digit fastball too good to pass up and drafted the hurler right after Houston took high school pitcher Brady Aiken first overall.

The $6 million bonus, which was first reported by MLB.com's Jim Callis, is the third-largest ever given to a high school pitcher (behind Aiken and Jameson Taillon) but will save the Marlins, as the slot value assigned to that pick was $6.8 million.

The Marlins have also agreed with second-rund pick Justin Twine for the slot value of $1.316 million, according to Jon Heyman of CBSsports.com.
