Seager was at Dodger Stadium for Saturday's game, taking pictures with Matt Kemp and taking batting practice with Don Mattingly, and he'll be reporting to play rookie ball in Ogden, Utah, in the next couple of weeks.
MLB.com has confirmed Seager's signing bonus is worth $2.35 million, more than the assigned value for the pick, which was $1.95 million.
For the humble and polite Seager, he's ready to get back on the field now that he's locked up.
"I'm just excited to be part of the Dodgers and get started right away," he said. "I've been ready to start, but that stuff has to get figured out first."
Playing ball is all Seager has wanted to do since being drafted by the Dodgers earlier this month. After being picked in the first round, the young infielder from Northwest Cabarrus High School in North Carolina just went out that night to play in his Legion game to get away from phone calls and text messages.
He was stranded in the on-deck circle that night as the batter before him ended the game with a walk-off hit, but he thinks he would've struck out with how excited he was to be drafted. One month later, he is just as excited to officially sign and, just like Draft night, he just wants to go back out and play.
Seager said he was committed to play for the University of South Carolina, but he changed his mind and opted to sign with the Dodgers instead. The team plans on keeping Seager at shortstop with hopes he can develop into a rare middle infielder with power.
The North Carolina native said his older brother, Mariners third baseman Kyle Seager, helped him a lot along the way with the decision process, from helping him with college choices to making sure he knows he's not going to be the only guy out of high school in the Minors.
He also prepared him for the challenges ahead.
"He didn't tell me it was easy," Seager said. "He told me it was a grind every day."
This was the second straight year Dodgers scouting director and assistant general manager Logan White worked out a deal with the team's first-round selection through agent Scott Boras.
"We see eye to eye a little more," White said with a laugh as Seager and Boras sat by his side in the Dodgers' dugout.
