Masterful unveiling: Joshua Baez first to hit 3 HRs in MLB debut

Joshua Baez might have made the best first impression in major league history on Saturday.

Baez became the first player ever to hit three ​homers in his big league debut, as he ‌helped the St. Louis Cardinals record an 8-4 victory over the host Chicago Cubs at Wrigley Field.

“It’s just unreal,” Baez said after delivering five RBIs. “To not only get a hit, but three ‌home ​runs? It’s crazy.”

Baez, 23, came up ⁠with one on in ⁠the opening inning and hit the first pitch he saw from Matthew Boyd 449 feet to center for his first homer.

He led off the fourth by belting ​a full-count changeup from Boyd over the wall in left to give St. Louis a 4-3 lead.

In ⁠the sixth, Boyd again couldn’t ⁠solve the rookie as Baez sent a ​1-0 slider over the wall in right for a two-run ​shot to make it 6-3.

“I was just really glad ‌that the ball went over the wall,” Baez said. “I had no idea. So I just started running, and then I seen that it went over and I ⁠was like, ‘This is insane.'”

Cubs manager Craig Counsell was amazed at what he was witnessing.

“He hit three different pitches for home runs. ⁠He had ‌a great game,” Counsell said. “He beat us ⁠for sure.”

Baez is St. Louis’ No. 3 ​prospect, ‌according to MLB Pipeline. He was recalled ​from Triple-A ⁠Memphis after drilling 34 homers in 103 games. He was batting .256 with 90 RBIs and 21 steals.

The Cardinals optioned third baseman Cesar Prieto to Memphis in a corresponding move. He was just 1-for-31 in 12 games with St. ​Louis.
