Boston English, Latin Academy and East Boston have clinched spots in the Boston City League baseball championships, according to a Boston schools’ athletic department official.

Boston International can clinch the fourth and final spot in this weekend’s championships by taking one game in a doubleheader against Charlestown on Thursday. If Boston International loses both games, however, Fenway High would sneak into the championships, the official said.

The top two teams from the North conference qualify for the city championships while the top teams from the Central and South conferences go to the championships.

In the North conference, Boston English finished in first place while three other teams (Latin Academy, Madison Park and Brighton High) tied for second place.

The tiebreaker for second-place in the North came down to run differential, which is the third in a series of tiebreakers. Latin Academy’s run differential was nine while Madison Park's was zero and Brighton’s was negative nine.

Brighton failed to qualify despite squeaking out a 4-3 victory against Latin Academy on Wednesday.

The semifinal games will be played at 10 a.m. and 1 p.m. on Saturday at English High while the championship game will be played 10 a.m. on Monday, also at English High.

The athletic department will announce the softball city championship matchups on Friday afternoon.
