The East Division-champion Detroit Tigers will help the American League open the 1988 season April 4 when they play the Red Sox in Boston, the league announced.

In other opening-day games, it will be Milwaukee at Baltimore, California at Chicago, Toronto at Kansas City, Cleveland at Texas and Seattle at Oakland.

The World Series-champion Minnesota Twins will play their first game April 5 against the Yankees in New York . . .

Boston Red Sox pitcher Bob Stanley was listed in good condition as he begins his recovery from tendon and nerve damage to his throwing hand, but the effects of the injury on Stanley's career may not be known for two weeks.

Stanley, 33, underwent four hours of microscopic surgery Friday to repair the damage after slipping outside his home in a Boston suburb and landing on broken glass . . .

Nellie Ruhland, a Baltimore centenarian whose dedication to the Orioles through thick and thin earned her the title of oldest living fan, died at a home for the poor at 104.

Her enthusiasm for the game became locally known after Ken Dixon, an Orioles pitcher, visited the woman and gave her a free pass to the team's home opener last year, said Sister Pauline Kelly of the home, which is operated by the Little Sisters of the Poor.

"This was her whole life," Sister Kelly said. "She wouldn't go to sleep when the Orioles were playing so she could hear" the games on radio.

Mrs. Ruhland said her husband, who died when both were in their 80s, told her before he died that, "Whatever you do, don't let the Orioles down," Sister Kelly said.

At age 101, she was evicted from her Baltimore apartment for failure to pay rent and moved into the Catholic order's home in Catonsville, a Baltimore suburb.
