The Giants are finally going to see Target Field in Minnesota next season. They also will pay a rare visit to Cleveland and start the year on the road as usual, if the tentative 2020 schedule is approved.

Opening Day is set for Thursday, March 26 at Dodger Stadium, which means the Giants would have to watch a World Series banner-raising if the Dodgers finally win their first in 31 seasons.

The April 3 home opener also is against the Dodgers. The Giants will finish the year at home, the upside to starting on the road, which they will do for the 11th straight season.

The Giants usually request road openers partly for that reason, and to get more dates when it's warmer.

The Giants will have visited Minneapolis once in the first 23 years of interleague play, in 2005, when the Twins still played at the Metrodome. They have been to Jacobs Field once as well, in 2008.

The Giants won both series. Sergio Romo made his big-league debut in the opener in Cleveland, striking out two of his three hitters in the ninth inning of a 4-1 loss.

Next year's tentative schedule has the Giants visiting Minnesota and Cleveland on the same trip, May 1-6. The Giants also will travel to Detroit in the middle of a three-city trip that begins in Denver on July 31 and ends in Philadelphia.

Detroit, Kansas City and the White Sox will come to San Francisco. The annual home-and-home against the A's will be on June 6-7 in Oakland and July 7-8 at Oracle Park.

All of the tentative Major League Baseball schedules can be changed before they are announced in September. They are sent to the teams and Players Association for review and alteration requests, which the league sometimes grants.
