Brian Costello 1990 Clinton Giants card
Brian Costello looks back to his first career as basis for his second.

Costello's first career was as an athletic trainer in the minors. His second, according to his practice bio, is as a physician assistant in 2017 at a California orthopedics practice.

"An area of interest for me is sports medicine," Costello's bio at Webster Orthopedics reads, "as I can use my experience in professional baseball to better care for our patients."

Costello's athletic training career lasted four seasons, from 1989 to 1992. He spent all four seasons in the Giants system.

He became a trainer out of Cal State Hayward. He earned a degree in physical education.

Costello started with the Giants at single-A Salinas in 1989. He moved to single-A Clinton for 1990, wearing a neck brace while mimicking a pitcher on his 1990 Best card.

His 1990 season is also when he received certification from the National Athletic Trainers Association. He then received his masters in sports medicine in 1992,

Costello served as trainer at AA Shreveport in 1991 and high-A San Jose for 1992, marking the extent of his minor league training career.

He later received his physicians assistant certification. By 2015, he'd joined Webster. He assists in total joint replacement surgeries, as well as other operations and clinical work.

Hitting against Seton Hall, Heckel picked up three hits, including a home run, helping his team to a 6-2 victory . Heckel's performance that year got the notice of scouts for the Blue Jays , the team taking him way down in the 65th round of the draft that year. Heckel instead stayed in school, but the Blue Jays didn't forget him. A year later, Heckel had improved his draft stock considerably, the Blue Jays taking him in the 12th round .

Astros farmhand Jimmy White assessed his progress in 1994 to his hometown Tampa Tribune . When he started four years earlier, he didn't know anything. He just went up and hit, he told The Tribune . "Now you look over how the pitcher pitched you last time. You go up there more prepared," he told The Tribune . "Things are a lot different. I'm more patient and confident." White made AA for the first time that season. In a career that spanned seven seasons , he didn't make it higher. White's career began in 1990, taken by the Astros in the sixth round of the draft out of Brandon High School in Florida. Ahead of the draft, The Tribune spoke to scouts to gauge his prospects.

In previewing the 1991 season, The Asheville Citizen-Times highlighted two of the team's pitchers as control pitchers, then two others, including Fionel Nieves , as having good fastballs. As it soon turned out, would soon show he was not the former .  Control issues would soon mean he would see only three starts. That season, his second as a pro , would also be his last.

The Louisville Courier-Journal checked in on Louisville RiverBats veteran top picks in June 2000, among them former Astros first-round pick Tom Nevers . By then, Nevers was in his 11th pro season, having started in 1990. The highest he'd gotten was AAA. "The media and the fans can take it as, 'Oh, you're a first-rounder, you're going to be a star.,'" Nevers told The Courier-Journal then. "But there are no guarantees in this game." Nevers went on to play in two more seasons. The former first rounder never made the majors . Nevers' career began in 1990, taken by the Astros 21st overall out of Edina High School in Minnesota. The Astros picked Nevers to play baseball as he also had hockey options.

Ahead of the 1989 NHL draft, Nevers spoke to The Minneapolis Star-Tribune about his options. "I lov...

Texas' Coppell High School lost the game and lost the pitcher The Fort Worth Star-Telegram described as the team's ace, Steve Boatman , then 13-2.

Taken in the second round of the 1989 draft by the Astros, it took 16-yea-old New York City high schooler Jermaine Swinton until that September to sign, Newsday wrote . The delay in choosing between college and the pros meant he missed the 1989 season, first hitting the field in 1990. "I would have been happy either way," Swinton told Newsday in July 1990 of his decision. "But it turned out to be a good decision ... I just followed my heart to play pro ball." Swinton's pro career ended up spanning more than a decade . He spent more than half of that in independent ball. He topped out in the minors at high-A. Swinton's career began that year in 1989, taken by the Astros 42nd overall out of Fort Hamilton High School in Brooklyn. After his selection in 1989, his coach spoke to Newsday . "It didn't surprise me at all," Fort Hamilton coach Jim Apicella told Newsday . "He has good speed and some tremendous power." Swinton started for t...
