Boston-born Joshua Baez sets a MLB record in Chicago.

Baez, 23, homers in his first three-bats in his first game in the major leagues for the Cardinals in a game against the Cubs at Wrigley Field. He was born in Boston, moved to the Dominican Republic with his family as an infant, then returned, and grew up in Dorchester, and attended Cristo Rey and Snowden International high schools, before being drafted by St. Louis.
