It already feels like I’ve written a short book on Kevin McGonigle since the 2025 season came to an end. Baseball’s consensus second ranked prospect entered major league camp knowing he already had the skills to make the Opening Day roster. Six weeks of excellent performance this spring under pressure to prove himself made it perfectly clear to all that the Detroit Tigers are a lot better team with McGonigle in the lineup and playing on the left side of the infield. We’ve called McGonigle the best prospect in the club’s history for over a year now. On Thursday he set about proving it with one of the best debut in MLB history, as he became the sixth player to record four hits in their first game. No one can predict a debut like that, but it’s become more and more clear over the past year that the Tigers’ have a pretty freakishly talented and composed young player here.
In Scott Harris’ first year running the Tigers, scouting chiefs Rob Metzler and Mark Conner hit a home run by drafting McGonigle with the 37th overall pick in the competitive balance A round of the 2023 amateur draft. They saved a little money on first round pick Max Clark’s signing bonus, as well as second rounder Max Anderson’s bonus, and that helped them to land McGonigle for a price of $2,847,500, which was about $550,000 over the recommended slot value. Money well spent.
McGonigle played his high school ball at Monsignor Bonnor HS in Drexel Hill, Pennsylvania, just outside of Philadelphia. His origin story is already taking on shades of Tigers Woods impersonating his father’s swing not long after he learned to walk, or Alex Honnold’s mother finding him high up in treetops when he was still a toddler. His mother told a story on the Opening Day podcast of a young McGonigle just 18 months old, stalking the house with a wiffle ball and bat, wanting someone to pitch to him. That love of hitting never left, and he and his father spent hours and hours watching footage of Tony Swynn and their favorite Philly, Chase Utley, to build his swing and approach at the plate.
On draft day, McGonigle was lauded for his outstanding eye at the plate and preternatual ability to barrel up any pitch in any part of the zone. Scouts wondered if he’d hit for average power based on his small, 5’9” stature, and his ability to stick as a major league shortstop was also in heavy dispute. Still, few wondered about the hit tool, and at least those assessments have proven prescient over the nearly three years since draft day.
By the end of his first pro season, concerns about power were put to bed, as McGonigle posted a few 109-110 mph exit velocities in Lakeland in 2024. He’s since topped out at 111 mph, into plus territory. His season ended with a fractured hamate, and so there was some fear that the power would take time to return. However, in 2025 spring camp, he quickly illustrated that he was 100 percent and posted plus exit velocities again. He was also hitting more and more balls to the pull field with natural loft, the perfect profile, while still being plenty capable of spraying line drives the opposite way and up the middle. And he does all this with low strikeout rates and a lot of walks drawn.
His 2025 season started with another unfortunate injury, as he sprained his ankle on Opening Day for the High-A West Michigan Whitecaps. Still, he returned without missing a step, teaming with fellow top prospects Max Clark and Josue Briceño at the top of the Whitecaps order to form one of the most dangerous lineups the Midwest League has ever seen. He crushed triple digit fastballs. He crushed changeups. He crushed breaking balls. There was simply no straightforward path to getting him out, and he and his teammates tore the Midwest League apart with the Whitecaps going on to post the best record (92-39) in the league’s High-A history.
Then 20 years old, McGonigle hit .372/.462/.648 with seven homers and 19 doubles in just 36 games. That was all the Tigers needed to see to promote him to Double-A Erie. There his batted ball luck hit a rough patch, but he still hit 12 homers in 46 games, walking far more than he struck out. By that point, we held the opinion that he was already the best minor league hitter the Detroit Tigers’ organization has ever produced.
McGonigle has an outstanding eye, but he’s not passively trying to take walks either. He’ll turn it loose first pitch, but while he’ll expand the zone against breaking balls and changeups, pitchers do not get him to chase the same way twice. In fact, he rarely chases much at all. He’ll be tested in the coming weeks as major league pitchers turn to throwing him a ton of breaking stuff, trying to get strikes and avoid throwing fastballs in the zone, and we’ll see how long it takes for him to adapt, but pitchers were already trying this late in camp without much success.
Because he’d missed some time to the injury, the Tigers sent McGonigle out for a month in the Arizona Fall League last October. The pitching competition wasn’t quite as good as he faced in Erie, and as expected, McGonigle tore the league to shreds en route to an MVP trophy. Even better, his defense at the shortstop position looked improved, and he played some third base as well, adding that to his toolkit after playing second and shortstop pretty much exclusively to that point. Getting those defensive reps was really the main point of the whole enterprise, and it has paid dividends this spring.
McGonigle was already like a fringe average shortstop, but he needed to clean up his defensive game and become more consistent and more efficient. At times, there would be bobbles, some double pumps to re-grip, and some routes to balls that left his momentum moving off line to first base when a better path would have gotten him in better position to throw. Tigers’ legend and Hall of Fame shortstop Alan Trammell, who had already worked with most of the minor league infielders at one point or another, then stepped in. Trammell took his own time to go out to the Fall League to work with McGonigle and fellow infield prospect Max Anderson on cleaning up footwork, glovework, and transfer, to help each get the most out of their skills. This really paid off.
McGonigle this spring has looked like a different man playing the infield. He’s been extremely efficient with less of the wasted steps and slow transfers we saw in his first two full seasons. He was always good with flips and tosses to second base, and he’s always had range, so he was working with a reasonable good base of skills. But that improved efficiency has countered his one “weakness” defensively. McGonigle has a good, accurate arm, but does have the cannon that many of the top shortstops around the game possess either. By cleaning up his game, McGonigle’s speed and range come to the forefront, and now he looks capable of playing above average defense at the shortstop position, as well as at second and third base. This was a pretty huge development, and perhaps the thing that carried him to making the Opening Day roster. We had no doubts by this spring that he was going to hit.
The final big note, and this is quite a huge development as well, is the 30.2 feet per second spring speed McGonigle recorded in his major league debut on Thursday. He also posted a 28.3 ft/sec mark and a 29 ft/sec mark on two other hits on the day. Trea Turner led all of baseball last year by averaging 30.3 ft/sec. I clocked McGonigle a few times last July as he made the jump to Erie. I never got a time over 29 ft/sec, so he clearly had speed, but I did not see that 30.2 ft/sec mark coming. Maybe the ankle was still bothering him a little throughout last season, but whatever the case, McGonigle appears to now have borderline elite speed to go with all his other attributes. Maybe he won’t average 30 ft/sec, but something around 29 would still be a full grade higher than we had him last summer.
The sky is the limit. McGonigle is going to be a very good player for a long time. He’s shown he can play average or better shortstop. He’s shown he can move around and play second and third as well. And we all know he can really hit and hit for plenty of power. He looks like one of the better pure hitters in the game, capable of 30+ HR seasons with low strikeout rates, the speed to steal 20 bases or more, all while playing sound defense at key positions.
The questions now are the really fun ones. Just how good can he get? As a young rookie, still only 21 years old until August, there may be some growing pains along the way. You can expect teams to immediately go full spin cycle against him in the weeks ahead as it becomes clear you can’t throw fastballs and changeups in the zone without paying the price. Once he adapts to that, it’s on. McGonigle is as close to a lock as it gets to be a well above average player for a long time. He’s also a pretty good bet to be a consistent All-Star caliber player for the Detroit Tigers for the next decade, and one of his generation’s top players.
