With 15 minutes to go before today's Friday 5 p.m. Eastern signing deadline, 15 picks in the top 10 rounds remained unsigned. From top to bottom, here's what happened with them:

Kevin Gausman (Orioles, first round, No. 4 overall): Signed for $4.32 million. That made him one of the few players to get more than his assigned pick value ($4.2 million ) in the first round. He got the third-highest bonus in the draft, behind No. 2 overall pick Byron Buxton ($6 million) and No. 1 overall choice Carlos Correa ($4.8 million).

Mark Appel (Pirates, first round, No. 8 overall): Did not sign. A source said Pittsburgh offered him $3.8 million, the most it could without forfeiting a 2013 first-round pick. Considered the likely No. 1 overall choice before the draft, he will return to Stanford for his senior season.

Lucas Giolito (Nationals, first round, No. 16 overall): Signed for $2,925,000. He likely would have gone in the top three picks had he not injured his elbow in March. While he didn't get the money he would have commanded at the top of the draft, he got well in excess of his $2,125,000 pick value.

Nolan Sanburn (Athletics, second round): Signed for $710,000, slightly above his pick value ($691,000).

Teddy Stankewicz (Mets, second round): Did not sign. A source said New York never came within 10 percent of his $680,400 pick value. Originally committed to Arkansas, he now plans to attend Seminole State (Okla.) JC.

Alec Rash (Phillies, second round): Did not sign. Philadelphia pulled its offer to Rash a week ago after he didn't pitch as well in Iowa's summer high school season as he had in the spring.

Avery Romero (Marlins, third round): Signed for $700,000. His pick value was $458,400, and the difference between those two figures and Miami's reluctance to pay a penny of draft tax cost the club promising 19th-rounder Cody Gunter. Gunter would have signed for $200,000 and will  head to Grayson (Texas) CC.

Kyle Twomey (Athletics, third round): Did not sign. Will attend Southern California.

Brandon Thomas (Pirates, fourth round): Did not sign. Will return to Georgia Tech for his senior season.

Colin Poche (Orioles, fifth round): Did not sign. Will attend Arkansas.

Andre Martinez (Twins, sixth round): Signed for $80,000. Shortly after the draft, Martinez agreed on a $260,000 bonus in a slot with an assigned value of $200,000. But a physical exam raised questions about his left (pitching) shoulder, so he took a discounted deal.

Preston Tucker (Astros, seventh round): Has not signed. But because he's a college senior with no eligibility, the deadline doesn't apply to him. Houston still expects to sign him later this month.

Nick Halamandaris (Mariners, eighth round): Did not sign. Will attend California.

Kevin Ross (Pirates, eighth round): Signed for $130,000. That's slightly less than his pick value of $138,200.

L.J. Mazzilli (Twins, ninth round): Did not sign. Will return to Connecticut for his senior season.
