Miami is not wasting any time before locking up its 2015 MLB Draft selections. The Marlins announced seven more selections agreed to contracts on Thursday, with second round pick Brett Lilek and third rounder Isaiah White among them.

Although the Marlins have yet to sign first baseman Josh Naylor, who was selected with the 12th overall pick in the first round, eight of Miami's selections picked in the first 10 rounds have been signed. Naylor is expected to sign next week, according to MLB.com's Joe Frisaro.

Naylor is not formally allowed to sign with the Marlins until he officially graduates from high school, which will come on June 25. It is not expected to take the Marlins long to sign the future infield prospect after he ends his high school career.

The Marlins are confident Lilek, a left-handed pitching option, and White, an experienced outfielder, can develop into well-rounded major league prospects, making the early signings notable. Fourth round pick Cody Poteet, fifth rounder Justin Jacome, tenth rounder Kelvin Rivas, 11th rounder Ryan McKay, and 19th round selection Curt Britt are now all under contract.

Frisaro adds Lilek was signed to a $1 million bonus, which is $196,000 under the slot, while White signed for the slot value at $698,100.

27 of the Marlins' 40 selections have now been signed. Here is a list of draft picks now under contract:
