PHOENIX -- Speak with D-backs 2012 first-round pick Stryker Trahan for a matter of seconds and you'll know how he was brought up.
Every time the high school catcher out of Scott, La., responds to a question, he begins with either a yes or no sir.
The 18-year-old's humbleness and maturity for his age were out in full display on Saturday when he took batting practice at Chase Field only hours after signing a contract with the D-backs. A baseball source said the deal is for $1.7 million, which was the assigned value for the pick.
"At school, it was something new they were trying where you had to answer yes or no sir, and he just stuck with it," said Stryker's mother, Donna, who was in attendance along with her son's father and little sister. "He's an awesome kid. The D-backs are getting a lot more than a good baseball player."
Taken No. 26 overall this week in the Draft, Trahan spent about 20 minutes Saturday taking swings with D-backs pitchers. In his first few sessions in the cage, the recent high school graduate's nerves showed a bit, but he eventually warmed up enough to hit consecutive homers into the left-field bleachers.
"I could've done a lot better. I was a little anxious," he said. "This is what I've always dreamed of. It's a dream come true just being in the stadium right now. I was in complete awe, seeing Justin Upton and all these other guys. It's awesome."
Trahan, who used a wooden bat this season to help prepare himself for the pro game, comes from a family rich in catching tradition. Both of his parents played behind home plate when they were younger.
"I come from a whole line of catchers," he said. "I feel like it's my duty to be a catcher for my family. I just want to be the best athlete I can be and make my town proud."
Trahan said the D-backs will keep him in Arizona until September, training and playing with other rookies at Salt River Fields.
"I'm really excited to get started," he said. "It's a great feeling. It's a real honor."
The D-backs also announced that they have agreed to terms with 30 additional selections from the Draft, including their first six.
