The dimpled grin transcends language.It speaks Spanish. It speaks English. It speaks Vladdy.Even pre-game warmups were an event at the Rogers Centre on Friday night, when top prospect Vladimir Guerrero Jr. made his major-league debut for the Blue Jays against the Oakland A’s. (Rick Madonik / Toronto Star)Says: Hello world, here I am!Leadoff double in the bottom of the ninth, scored tied 2-2 with Oakland. Deep into the right-field corner.So hey, how do you like Vladimir Guerrero Jr. so far?“Just the way I dreamed it.’’Maybe not quite. Maybe a walk-off home run starred in that CinemaScope dream, reprise of a year ago in Montreal, exhibition intro to the city of his birth. But the winning run crossing the plate — albeit Alen Hanson pinch-sprinting for Guerrero — was debut dandy.And every move he made applauded by a Vladdy-giddy crowd at the Rogers Centre.“I was just concentrating on every at-bat,” he said later, after the Jays celebration at the dish, after the Brandon Drury home run, after the Blue Jays’ 4-2 win over the A’s. “I was just trying to do my job. It was exciting.’’A bundle full of words from the newly minted Major League Baseball player, delivered through team translator Hector Lebron.Trundled pre-game, pre-debut, into a jam-packed press conference, shaking hands with every stranger standing along the wall as he made his way to the dais — kind of like a political candidate ascending the stage at a rally.Somebody pass the dude a baby to kiss.Except he’s the bouncing baby Blue Jay, his arrival so eagerly anticipated and have-a-cigar celebrated.The only words we heard Guerrero utter in English on Friday, after the translated Q&A with reporters, after the fist-bump greetings, after the click-click-click of cameras that had trailed him into the Rogers Centre — wearing an Expos jersey over jeans, on his maiden day as a big-league ballplayer — were these, directed at a club PR employee: “The answers were good?”That’s kind of sweet, that Guerrero would have been anxious about how he came across, amidst the media maelstrom.He did just dandy.A twinge of nerves could have been expected. Except Guerrero — the future and the franchise — has never shown even a flicker of unease or discomfort in the spotlight, not even the three years he’s been under the glare, waiting to launch.“First, I want to thank God, my family, my people in Dominican Republic and all the entire Blue Jays organization for giving me the opportunity to play the best baseball in the world.”Well, that’s how the translation came through.What’s also beyond need of interpretation: The three bombs Kid V.G. Jr. blasted over the fence during BP, prior to the Jays hosting Oakland, each wildly cheered by a first-through-the-gate audience.Ovations came quick and often at the ballpark that Guerrero will call home for … oh … the next 15, 20 years, God willing.A good-sized (the Vladdy Effect) jazzed-up crowd brought the love as Guerrero stretched in the field, took ground balls at third base, hit in the cage, trotted out for the national anthem, made his first real play (scooped up a ball trickling foul) and, oh yeah, came to the plate for his first major league at-bat.“LET’S GO VLADDY! LET’S GO VLADDY!’’Hard to tell who wanted it more — a hit, a signature Guerrero jack — the player or the spectators.He had the nerve to stare down the first fastball from A’s pitcher Mike Fiers. Took it for a ball. Then fouled one back into the stands — 1-2, 2-2 and … a liner straight to first baseman Kendrys Morales, so recently, at spring training, his teammate and pseudo-daddy.“That was the first thing I did, send Kendrys a message,” said Guerrero, about informing the traded-away Jay that he’d been called up. “He told me that he was very, very proud of me.”An anti-climactic virgin at-bat, but no matter. Plenty of bops in that stick. With that powerful swing. With that discerning eye — walks more than he strikes out. And hell if Guerrero, batting fifth, didn’t nearly sock one over the fence in his second trip to the plate — a parabola caught at the wall in left field, 328-foot ride.Giant roar of encouragement also when Guerrero made his first out, charging the ball, throwing across the diamond to get Stephen Piscotty out at first, receiving a low-five of appreciation from starter Marcus Stroman. “I let him know right on the spot how I feel about it,’’ said Stroman of Guerrero’s slick defence.Then — THWACK — that leadoff double in the bottom of the ninth, score tied 2-2, clapping his hands, self-applause, stoked as he stood on second base, lifted for Hanson. And very much part of the pile-on revelry at the dish after Hanson and Drury — displaced as third baseman by Guerrero — came bounding across home.Just another Jay, in those seconds. Just another winning baller.His destiny, though. Written in the wind, under the Dominican sun, in the family DNA. Wearing his hall of fame father’s No. 27.With pops Vladimir Guerrero Sr. beaming, savouring this second-generation thrill — that chubby little boy who doffed his helmet and saluted the crowd at Olympic Stadium, standing alongside his dad. Now a big strapping boy of 20, with peroxide tipped dreadlocks — they look like Cheetos — the gaudiest prospect in all of baseball.“He was born in Canada, in Montreal,’’ said Sr., bustin’ his buttons. “And now he gets to play his first game in Canada. I’m just so happy about that.’’A gesture from the son to the father, that No. 27 Vladdy — because surely he will henceforth and always be known as just that, Vladdy — on the back of his Jays jersey.“It was more like honouring my dad. Since I was a kid I was running around with my dad in the clubhouse in Montreal. I wanted to bring that back today.”Giving pops that double hit ball, too. “And the bat. Everything is going to my dad.”A remarkable day for the Vlads. A remarkable day in Toronto’s sporting history, with lots of giddiness and benevolent feelings, just the tonic for a city to get its chin off the ground after another traumatizing Game 7 playoff loss by the Maple Leafs.“As he walked into the clubhouse yesterday, seeing him here put a massive smile on my face,’’ said GM Ross Atkins. “I think that’s what this means for so many. It’s an exceptional day.’’Silly episodes too, on Friday. Such as reliever Joe Biagini — team goofball — striding across the clubhouse, dropping to his knees, and kissing Kid V’s hands.They’ve given Guerrero a cubicle next to Clay Buchholz and the empty locker of injury-rehabbing Ryan Borucki, nowhere near any of the many Spanish-speaking Jays. But maybe there’s cunning to that also, encouraging Guerrero to speak English. Thing is, he clearly understands it just fine, his eyes sparkling with comprehension when questions are posed. He starts to answer in his native tongue before the query is translated.But of course he’s had three years of minor-league ball in North America. And he’s a clever young man. Not just baseball IQ either. Knows the right things to say, making a good first impression, and appearing quite genuine about it.“Basically I’m very happy, very proud myself of making my debut here in Canada.”Though Lord knows they made him wait long enough, the panjandrums of Blue Jays baseball who didn’t bring Guerrero up for a taste last September and then, with the oblique injury he suffered at spring training, a handy excuse to delay his debut in 2019 — manipulating and thereby maximizing his service time blah-blah-blah. Blessedly a topic that can be set aside now.“We have a Canadian-born Dominican baseball player, son of a hall of famer, that is coming into Canada to play for this great city and country,” Atkins said at the pre-game media confab.At least he had the grace to mention, however peripherally, all the Vladdy-spotters who were here before him, before president Mark Shapiro, most crucially ex-GM Alex Anthopoulos, who recognized in a 15-year-old Guerrero a gem in the not-so-rough, and signed him as a teenager, expending the entire international baseball budget on a $3.6-million U.S. bonus for the prodigy.Hail Alex, down there Atlanta way.So many baseball savants have had their eyes and their mentoring hands on Guerrero along the way. But he — whether by genes or desire or inspiration — is very much his own creation, so poised and unaffected by all the surrounding hype.Manager Charlie Montoyo, drooling over his unwrapped toy, could scarcely fathom Guerrero’s preternatural calm, breaking his MLB maiden. When he, Montoyo, had been such a bundle of frazzle on the night he made his debut — as an Expo and teammate of Guerrero Sr.“Never seen it. Not anywhere. It’s pretty cool to be that cool.’’But of course Guerrero has forever been surrounded by ballyhoo and The Show was never a foreign country, from his Expos rugrat days.The Jays made the call to Buffalo on Wednesday and put out the word — Vladdy’s-a-coming — when the Bisons were in Syracuse, where Guerrero had just tattooed his fourth homer. Guerrero called home, to kinfolk on the island: “I told my entire family to make sure to get here to Toronto to see me play in the first game. I haven’t had the chance to talk too much with my teammates because, I mean, everything happened so fast.”It only happens once, that first time.“I’m going to play hard. give my 100 per cent for the team and whatever happens, happens.”It sounded sexier in Spanish.Rosie DiManno is a columnist based in Toronto covering sports and current affairs.
