What happened: Báez homered on the first Major League pitch he saw. He went deep in his next two at-bats and drove in six runs.
Why it matters: No player had opened an MLB career with home runs in each of his first three at-bats. The power display turned his call-up into an immediate entry in the record book.
By the numbers: 3 at-bats, 3 home runs, 6 RBIs; first home run: 449 feet.
What to watch: Báez's next start will show how pitchers adjust after his unprecedented debut.
