The Detroit Tigers have signed No. 1 pick Casey Mize to a record $7.5 million bonus.

"It's such an honor to be the first overall pick and join a great organization like the Tigers," the former Auburn right-hander said. "I'm really appreciative of them considering (me) the best player in the draft and taking me with the first selection. For it to be official, it really feels great."

The $7.5 million signing bonus is the second largest in draft history and the record under the current bonus pool system, which was implemented in 2012.

The San Francisco Giants signed Georgia Tech catcher Joey Bart, the No. 2 overall pick in the MLB amateur draft, on Sunday.

According to MLB.com, he signed for $7.03 million -- the highest up-front bonus paid to a position player in MLB draft history. Despite that, the Giants were able to sign him below the slot value assigned to the pick, which was $7,494,600.

The San Francisco Giants are closing in on a deal with second overall pick Joey Bart.

The Georgia Tech catcher only needs to pass a physical to complete the deal.

Bart is expected to sign for slightly less than the $7,494,000 million slot value for the No. 2 pick.

The Philadelphia Phillies have agreed to a bonus with No. 3 pick Alec Bohm.

Bohm, a third baseman out of Wichita State, will receive a bonus in the range of $6 million.

The third overall pick comes with a $6,947,500 slot allocation.

The St. Louis Cardinals have agreed to a bonus with first-round pick Nolan Gorman.

The 19th overall pick will receive a full-slot bonus of $3,231,700.

Gorman is a high-school third baseman from Arizona. He is believed to be the hardest hitter among this year's draft class.

The Texas Rangers are nearing an agreement on a contract with first-round pick Cole Winn.

A pitcher out of Orange Lutheran High School (CA), Winn was the 15th overall pick earlier this month.

Winn is expected to sign for close to the $3,738,500 slot value attached to the selection.

Kyler Murray has agreed to a contract with the Oakland Athletics that will guarantee him $5 million and allow him to play football for the Oklahoma Sooners this fall, according to a report.

The A's drafted Murray, an outfielder, with the ninth overall pick on Monday.

He told Oakland officials Monday night that he will put baseball off and honor his commitment to Oklahoma. The slot value for the ninth pick in the draft is $4.7 million.

The Oakland Athletics drafted Oklahoma quarterback Kyler Murray with the ninth overall pick on Monday night.

The assigned value of the ninth pick is $4,761,500.

Murray is projected to start for the Sooners with Baker Mayfield in the NFL.

"Right now I'm not focused on the baseball-football situation," Murray told reporters, while adding that he planned to play football in 2018.

Murray could sign with Oakland and still play at least this season for the Sooners.

The Detroit Tigers used the first overall pick on Auburn right-hander Casey Mize.

It was the second time the Tigers held the No. 1 pick and the first since they drafted Rice pitcher Matt Anderson in 1997.

"It means a ton," Mize told MLB Network. "I can't describe this feeling right now."

Mize is 10-5 with a 2.95 ERA, 151 strikeouts and 12 walks in 109 2/3 innings while helping the Tigers to the NCAA Tournament.

In a statement, Al Avila said the Tigers are confident that Mize "will become a pillar in our player development system that's going to bring winning baseball to Detroit for seasons to come."

The Minnesota Twins traded Phil Hughes to the San Diego Padres last weekend.

San Diego sent prospect Janigson Villalobos to Minnesota. Hughes has $22 million left on his deal and the Padres will receive $7.6 million this year and $7.25 million next to offset that.

The Padres will also get the 74th pick in this week's draft along with the 812,200 in bonus pool money that goes with it.

Essentially, the Padres are paying $7 million for the competitive balance pick. When the Twins designated Hughes for assignment, they appeared willing to eat all of the $22 million remaining on his deal.
