DETROIT — The Kevin McGonigle era begins now.

The Detroit Tigers announced Tuesday they will carry McGonigle on their Opening Day roster, leaving baseball’s No. 2 prospect set to debut on Opening Day against the Padres in San Diego.

The 21-year-old McGonigle will skip Triple A and play in the big leagues after only 46 games last season in Double A.

McGonigle blazed his path to the roster by posting a .923 OPS in Grapefruit League play this spring. McGonigle hit .250 with a .423 on-base percentage, blasting two home runs in the Grapefruit League and another 461-foot shot against Luis Severino in an exhibition game against the Dominican Republic National Team.

For all his success, McGonigle also got a taste of the major-league learning curve. He cooled to a 4-for-27 finish to camp as pitchers began attacking him more with offspeed and breaking balls. Though he squared up fewer pitches during that stretch, he mostly maintained a mature plate approach, ending camp with 11 walks and only eight strikeouts.

“He’s a really good player,” Tigers manager A.J. Hinch said. “He’s a quick learner. I think his ability to process everything from subtleties within the positions to feedback when he makes a mistake is a great sign for a young player who is trying to find his way. He’s not overwhelmed by the moment. … He’s had an impressive camp production-wise, which is what everybody sees. But a lot of the little details, he’s excelling at.”

Just as importantly as his damage with the bat, McGonigle was rock solid defensively, answering perhaps the biggest question evaluators both internal and external might have had. McGonigle played in 10 games at shortstop, showing improved footwork and timing. He also played seven games at third base, where he could eventually have the best chance to become a plus defender.

“He’s done a great job on just coming in on balls or playing some balls one-handed, some of the technique stuff,” said Ryan Garko, the Tigers’ assistant GM who heads player development. “I think having watched him all these years and all of a sudden now you’re on a field with bigger, faster, stronger players, he’s done a really nice job making some really tough plays look pretty easy.”

Behind the scenes, McGonigle also thrived, showing a cool and composed demeanor but also looking undaunted on the field with major-league players.

Because McGonigle is on the roster, he will have a chance to earn a full year of major-league service time. Via MLB’s Prospect Promotion Incentive, the Tigers could gain a draft pick in the event McGonigle wins American League Rookie of the Year or finishes in the top three of MVP voting at any point before he reaches arbitration.

For now, McGonigle will join a Tigers team coming off back-to-back playoff appearances and looking to up the ante after the offseason additions of Justin Verlander and Framber Valdez.

And from everything we’ve seen, he looks ready for the challenge.

“The quiet confidence and the grittiness, the steadiness, is always the same,” Garko said. “I don’t think anyone on our staff ever saw Kevin go through the normal emotions and ebbs and flows any young player tends to go through. It is just who he is as a person. It’s a slow heartbeat with an ultra-grinder, competitive mindset, as well. It’s pretty unique to have both of those things.”
