The Pittsburgh Pirates have landed themselves a generational kind of player in rising star Konnor Griffin. In Spring Training so far, Griffin has been very impressive and is being compared to players of the past who made their MLB debuts with roughly the same amount of inexperience and youth in their professional careers.
At just 19-years-old and only one professional season under his belt, Griffin is looking to do what very few have done and that’s make an MLB opening day roster as a teenager. The Mississippi native has already found himself in a small group of players with the kind of hype that he has generated, but he’s in line to be in an even smaller fraternity if he can crack the Major League level this season.
Over the last 40 years, there has only been four players to see time on a big league roster as a teenager and with so little experience in the Minor League ranks. Those four players are Ken Griffey Jr., Bryce Harper, Alex Rodriguez and Juan Soto. All four of those players were highly touted in their respective draft classes and have gone on to become all-time greats in the game of baseball, and now Konnor Griffin has a real shot at being mentioned in this rarified group.
The most notable of this group is without a doubt Griffey Jr. who made the Seattle Mariner’s opening day roster at 19-years-old in 1989 after being drafted first overall in 1987. “The Kid” went on to have one of the most storied careers of any player in MLB history amassing 10 Gold Gloves, seven Silver Sluggers and was a 10 time All-Star and was the AL MVP 1997.
Bryce Harper was one of the most highly touted prospects in baseball history and ended up dropping out of high school after his sophomore year to play college baseball at Southern Nevada. Regarded as a true five-tool player Harper primarily played catcher but was drafted first overall as an outfielder by the Washington Nationals in 2010 in an effort to maximize his talents and get him to the Major League roster faster. It took little time for Harper to make an impact in Washington as he spent just one season in the Minor Leagues before being promoted to the majors in 2012. Harper is one of the most dangerous hitters in baseball and is an eight time All-Star selection, a two time NL MVP, was the NL Rookie of the Year and is a four time Silver Slugger.
Perhaps the most controversial player of this fraternity is Alex Rodriguez. After being drafted first overall in 1993, Rodriguez made his professional debut in 1994. On July 8, 1994 Rodriguez would make his MLB debut as an 18-year-old. At the time he was just the third 18-year-old shortstop in MLB since 1900 and was the youngest player to ever suit up for Seattle. He remains as the last 18-year-old to play in an MLB game. “A-Rod” became a World Series champion with the New York Yankees in 2009 and is also the recipient of the most Hank Aaron Awards with four. His history with PEDs will likely keep him out of Cooperstown but there is no doubt he is one of the most successful baseball players of all time, especially considering he made his MLB debut at just 18.
The most recent draftee of this group (so far) is Juan Soto. The Dominican superstar was signed by the Washington Nationals in July 2015 and made his professional debut in 2016. When Soto made his MLB debut in 2018 he was the youngest player in the majors at 19-years-old and was the first player born in 1998 to appear in an MLB game. Even at a young age Soto was a feared hitter. He became the youngest player since Griffey Jr. to be intentionally walked in a game and was the youngest player in Nationals history to hit a home run. Soto became a World Series champion with Washington in 2019 and is a six time Silver Slugger Award winner. Soto signed the largest contract in professional sports history during free-agency in 2025.
Griffin has one minor league season under his belt in which he was very impressive. Baseball America named him the top Minor League player of the year in 2025 and a Minor League All-Star. USA Today named Griffin the top Minor League player of the year as well. He was also named a Rawlings MiLB Gold Glove award recipient. Griffin finished the 2025 season with a slash line of .333/.415/.527 to go along with a .942 OPS, 21 home runs, 94 RBIs and 65 stolen bases. Now in just six Spring Training games Griffin is the first teenager to have three homers in a single Spring in at least 20 years.
On paper, this is the best looking Pirates team in at least a decade if not longer, and Griffin could certainly be a player that puts them over the top. If he doesn’t make the opening day roster, there is a strong probability that he’ll still make his MLB debut in 2026, and if he’s half as good as any of the other aforementioned players, the league is going to have to recognize that the future of baseball has a name; that name is Konnor Griffin.
