Cardinals 8, Cubs 4: Báez Homers in First Three ABs of Debut

August 15, 2026 - Chicago - Joshua Báez saw one pitch in the major leagues and put it halfway up the Wrigley Field bleachers. He grinned at the dugout on the way around the bases. Then he did it again. Then he did it a third time, opposite field, same starter still on the mound. The St. Louis Cardinals beat the Chicago Cubs 8-4 because a kid called up that morning wrote a debut nobody had ever seen.

Báez went 3-for-4 with three home runs and five RBIs. Major League Baseball said he was the first player in the modern era to hit three home runs in his debut. He was the first to do it in his first three at-bats, period. Thirty family members were in the seats. Rain still came later. The photos on the field still happened.

First pitch, then left field, then the other way

Matthew Boyd (8-2) threw the first pitch of Báez's career. It traveled an estimated 449 feet into the left-center bleachers, a two-run shot that announced everything St. Louis wanted from its No. 3 prospect. Michael Conforto answered with a three-run homer in the second and tied the game at 3-3. Boyd still had to face Báez again.

In the third, Báez worked a full count and ripped a changeup 382 feet down the left-field line for a solo shot that put St. Louis back in front 4-3. In the sixth he faced Boyd a third time and went the other way, a 368-foot line drive that cleared the right-field wall for another two-run homer. Five RBI. Three different parts of the yard. Three different pitches. Boyd's afternoon was already over in spirit before Blaze Jordan's homer finished the outing.

Boyd lasted 5 1/3 innings: five hits, seven earned runs, three walks, two strikeouts, four home runs allowed. "He's a good player. There's a reason why he's called up," Boyd said afterward. "He just, he got the better of me today." Cubs manager Craig Counsell kept it shorter: Báez beat them for sure.

McGreevy under the dugout, history on the monitor

Michael McGreevy (5-9) won for the first time since July 8. He worked six innings, five hits, two walks, six strikeouts. Three runs scored, all unearned. On a humid Wrigley afternoon he spent stretches under the dugout and watched Báez's second and third homers on a monitor. When his own day ended, he found the only sentence that fit.

"I love when history gives me run support," McGreevy joked. He also said the clubhouse knew the power was real from Memphis. Thirty-four Triple-A home runs will do that. Three in three at-bats still left everyone searching for words.

Burleson added a solo homer off Colin Rea in the eighth. Jordan's shot had already closed Boyd's ledger. The Cardinals piled enough cushion that Chicago's early punch, Conforto's three-run swing included, never became a second half story.

Line: Cardinals 8 runs, enough damage to make one debut immortal; Cubs 4 runs on a day their starter could not solve a first look.

Marmol watched it like a fan

Oliver Marmol had talked Friday about the edge and confidence that "screams at you" when you watch Báez for any length of time. Saturday he got to stop managing for a few seconds and just look.

"There was a calmness and a smile, like, 'I'm here,'" Marmol said. "It's rare for me to pick my head up to enjoy parts of it. He didn't exactly give us an option but to actually take a step back and enjoy the heck out of what was going on there."

Báez's own take stayed simple. "It's just unreal," he said. "To not only get a hit, but three home runs? It's crazy." The CBS postgame version ran close to the same place: unreal, a dream, words that refuse to land when the ball keeps leaving the yard.

He is the ninth Cardinals player to debut in 2026 and the first St. Louis player to homer in his first plate appearance since Lane Thomas in 2019. He also joined a short club list of Cardinals who went deep on the first pitch of their careers. Adam Wainwright did it as a pitcher in 2006. This one was different. This one kept going.

Both clubs sat at 62-61 after the final. Chicago had won nine of 11 entering the afternoon. St. Louis had dropped the series opener. One call-up flipped the vibe of the whole weekend.

Sunday: Hunter Dobbins (2-3, 3.40) for the Cardinals against Edward Cabrera (5-4, 5.10), back from a left hamstring strain for his first start since June 23.

I would not rewrite Boyd's season from one Saturday. I also would not pretend the debut was anything but historic. Three swings. Three souvenirs. One afternoon that Wrigley will talk about for a long time.

AthX Engine angle

Báez scored about 17 AthX Engine hitting fantasy points on the debut that will live longer than any daily board. McGreevy added about 24 pitching fantasy points while the runs behind him stayed unearned on his card. The Cardinals finished near 14 team fantasy points. That is AthX Engine (our projection and scoring system) grading a night that needed almost no help to look loud.

Fantasy points measure what a player did. Price is what the market will pay. They move together, but they are not the same number.
