Last year, Jacob Nix thought he hit it big in the 2014 MLB draft. But after he and top pick Brady Aiken were rejected by the Astros, Nix is hoping to hit it bigger this year.

On a still March afternoon in Texas, Jacob Nix kicks and delivers. Flashing a 94-mph fastball, a hard slider and a sharp curve, he throws six scoreless innings, allowing two base runners and striking out 13. His team holds on for the 7–1 win. It’s the kind of performance the Astros had in mind when they selected Nix in the fifth round of the 2014 draft and offered him first-round money.

But Nix is not in Houston. He’s 174 miles northwest of Minute Maid Park, at Division III Southwestern University in Austin, playing for the postgrad program at IMG Academy. The guys around him are mostly young strivers taking one last shot at a scholarship after disappointing senior years or kids who played out their high school eligibility but haven’t yet graduated.

Wrapping up a long spring training with its 10 biggest storylines

Most of them only dream of pro ball. Nix, 19, is simply biding his time until he can be drafted again. Last June, he became the first player in MLB history to be picked, offered a contract and pass a physical, then have his deal pulled. Nix never envisioned pitching in Texas while the Astros were holding spring training in Florida. But he has no regrets. “After the way things went,” he says, “any day of the week I’d take Southwestern over Minute Maid.”

Thanks to his spotty performance and his monetary demands, no one took Nix in the first two rounds of the June draft, and he went to bed after the first day assuming he would play college ball. As the fourth round ended, his adviser, David O’Hagan of Excel Sports Management, texted, “You’re gone.”

As he and his family rushed out to buy Houston hats, Nix thought of the years of 6 a.m. lifts, spring breaks spent at the ballpark and missed parties. “It all paid off,” he says. “In that moment it was all worth it.”

On June 24, Nix boarded a one-way flight to Houston, where he planned to take his physical, sign his contract and then fly to Kissimmee, Fla., to join the rookie-level Gulf Coast League Astros. At the hotel, the Nixes ran into Brady Aiken and his family. The Astros had taken Aiken, a high school lefthander from San Diego, with the No. 1 pick, and he too was in town for a physical and signing ceremony. The two players, good friends from their days on the 2013 USA Baseball squad that won gold at the U18 World Cup, were set to be introduced together.

In retrospect, Nix’s mother, Cindy, realizes she should have known something wasn’t right. Aiken had already taken his physical that day, and well into the evening Astros officials kept pulling him and his family into conference rooms.

The next day, after a doctor gave Nix the thumbs-up and welcomed him to the Astros, his family returned to the hotel only to see the Aikens, including Brady, in the lobby with all their luggage. After an hour of confusion, Houston director of amateur scouting Mike Elias summoned the Nixes to a meeting, where Elias explained that the Astros were very excited to have Nix, but there would be no signing. The team needed to work some things out and would be in touch soon.

Nix flew home with his family and tried to get used to something he hated but would become good at: waiting. “I’ve never been that kind of guy,” he says. “I’ve always been out doing something.”

Looking to escape AL West cellar, Astros place faith in streaky hitters

Before the current collective bargaining agreement took effect in 2012, teams could select college-bound players and throw money at them to entice them to skip school. This led many players to scare off small-market teams—often the ones with the highest picks and most in need of talent—by making it known that they would require a large bonus to sign. To combat the problem, MLB and the players’ association agreed to impose a salary slot for each pick position. If a team signs a player for more than his allotted dollar figure, it has to make up the difference by signing one of its other draftees for that much less. There are heavy penalties for going over the limit, and if teams fail to sign a pick, they don’t just lose the player—they lose his slotted amount from their pool.

As the top pick, Aiken was slotted for $7.9 million, while Nix’s fifth-round spot held a value of $370,500. But the Astros had worked out a preliminary deal to sign Aiken for $6.5 million, allowing them to divert $1.4 million to Nix. Everything looked good until Houston’s doctors raised concerns about Aiken’s UCL. The team dropped its offer to $3.1 million. Aiken declined. If the Astros didn’t sign him by 5 p.m. on July 18, they would lose him and his slot money, which meant signing Nix for so far above his slot value would cost them two future first-round picks.

Nix waited two weeks to hear what was holding up his own signing. Although he and Aiken shared the same adviser and were friends, Aiken had to keep his negotiations secret. Nix found out about Houston’s medical concerns the same way the rest of the world did: on Twitter.

Then Nix waited another week to hear whether his deal would come together. At last, a little more than an hour before the signing deadline, he says he got an email from Astros general manager Jeff Luhnow with a revised offer: $616,165. Nix passed and, with the backing of the union, filed a grievance—which jeopardized his NCAA eligibility, locking him out of his UCLA scholarship. He spent six months at home, watching Sons of Anarchy on Netflix and playing catch in the park.

The grievance dragged until mid-December, when the Nixes and the Astros worked out a settlement. (Both sides refuse comment, but the Houston Chroniclehas reported that Nix received a six-figure sum.) January came. The NCAA still hadn’t ruled on his eligibility, so when Nix heard about IMG Academy, a pre‑K-through-12 sports-focused prep school in Bradenton, Fla., that also offers camps and postgrad programs and is run by the powerful sports agency, he jumped at the chance to get away.

American League's biggest questions, battles as spring training ends

“This could’ve been the best thing for him,” says Dave Coggin, Nix’s personal pitching coach in high school. “He’s gotten so much life experience in the past year.”

When Nix first stepped on the mound for IMG, on Feb. 5, he was shocked to see nearly 80 scouts crammed behind the backstop. He didn’t disappoint them, tossing four scoreless innings with seven strikeouts against Webber International, an NAIA program.

He’s continued to impress, showing an improved curveball thanks to a new grip in which he uses the tip of his index finger to spike the ball. He’s also learned that he doesn’t have to throw his fastball, which tops out at 97 mph, as hard as he can every time. His mechanics have improved, although he still struggles with consistency of release point at times.

“He’s like a kid who just got his driver’s license and his first car is a Lamborghini,” Coggin says. “He didn’t know how to hit the gas yet just a little bit to still go as fast as everybody else. He kept hitting the gas like you would in a regular car, and it goes all over the place.”

It makes sense that Nix is still learning the craft. He had to sit out a full year when he was 12 due to a congenital back problem, since corrected by surgery, and he played catcher until his freshman year, when his team needed an emergency starter. Nix threw a five-inning no-hitter. You can toss your catcher’s gear, the coach told him.

He was devastated. “Why can’t I hit?” he whines even now, as IMG Academy officials give a tutorial on the video camera setup in the batting cages. But he’s come to love life on the mound. The same things he liked about catching are true of pitching—the control over the outcome, the involvement on every play, and the responsibility.

He’s not taking classes at IMG—full-time baseball just like the pros—and he was rooming with Aiken, who justified the Astros’ concerns about him when he had Tommy John surgery last week. Nix, who will head home in May to work out for teams before the draft, is expected to go in the first round and improve upon last year’s bonus offer, because he’s both pitched well and pitched often.

“His crew did a really nice job getting him to IMG so early,” says Keith Law, who covers the draft and minor leaguers for ESPN. “He was scouted very heavily because the weather was so bad across the country. There’s a comfort level with him.”

There is one team, though, that won’t have him on its draft board. Nix did not sign the papers that would allow Houston to redraft him. “I hear nothing but good things about 29 teams,” he says. “I just want to get in and start my career.”
