Tuesday's full slate of Boston schools' baseball and softball games has been canceled due to inclement weather, wreaking havoc on the race for the city championships. The softball and baseball city championships are slated for this weekend but mother nature is making it difficult to determine who will be playing.

In softball, East Boston (9-6, 8-0) and O’Bryant (7-5, 7-3) are poised to represent the North conference in the city championships while Latin Academy (9-10, 7-0) and South Boston (9-3, 9-3) and Dorchester (8-3, 8-3) are fighting for the South conference slot.

The forecast isn’t much better for Wednesday, when Brighton and Latin Academy are slated to square off in a baseball battle that could be the key to determining who represents the North conference in the baseball city championships.

In baseball, the top two teams from the North conference qualify for the tournament so
English High is also in the running to make cities.

The top team from the Central and South also qualify for cities. East Boston is looking like the runaway leader in the Central conference while Boston International and Fenway are battling to represent the South conference.

International (8-3, 5-1), which has already had eight or nine rain outs this year, has several conference games to make up this week. They are slated to play a double header against Charlestown on Thursday and back-to-back games against Snowden and Burke on Friday.

Boston International coach Christian Irizarry said he has plenty of pitching to get his team through the nonstop schedule of games.

“I have five arms besides my regular pitcher,” he said. “So for our league we are pretty good in terms of pitching.”

Fenway (9-7, 7-3), which clinched the state tournament for the first time in eight years on Monday, feels like they deserve to be the South representatives in the city tournament, especially because they defeated Boston International, 8-4, on Saturday. International beat Fenway 6-5 earlier in the season.

First-year Fenway coach David Walsh said his team would go to cities if the tiebreak came down to runs scored.

“We would definitely do damage in the cities,” he said. “If we don’t get in at least I know we’re in states.”

If the remainder of Boston International’s league games are rained out, it’s unclear how they will be counted in the standings.

“If I don’t play anyone because of the weather why should [Fenway] be on top?” Irizarry said.

The baseball city championship semifinals will be at 10 a.m. and 1 p.m. on Saturday at English High. The title bout will be on Monday at 10 a.m.

The softball semifinals will be at 11 a.m. at Clemente and Cobe Fields in the Fens. The championship game will be at 10 a.m. on Monday at Cobe Field.
