"Going to Fenway Park for Red Sox-Mariners Saturday? Bring a box of tissue. Bring your checkbook, too. Boston's ancient baseball theater will be one of 15 major league parks honoring the 70th anniversary of Lou Gehrig's farewell speech ("I consider myself the luckiest man on the face of this earth'') and raising funds to support ALS research. It's called "4ALS Awareness''

Nice going, MLB. In 1939, amyotrophic lateral sclerosis took Gehrig off the field after 2,130 consecutive games and now baseball is joining the fight against the deadly disease.

"We're involved with a whole series of charities,'' explained commissioner Bud Selig. "We get asked a lot. But I've had inquiries about ALS from a fair number of people over the years, because of the Lou Gehrig connection. I said to myself, 'This disease is so horrible and it affects so many people and it's as dreaded today as it was in 1939.' This is our chance to increase awareness, raise some money, and reach out to all the people affected and show people we do care.

"I can't give any more reason than that. That's how it happened. I wish my other decisions were as easy as this one.''

Throughout baseball Saturday, players will wear 4ALS patches. First bases (Gehrig's position) will be auctioned, and during the seventh-inning stretch there will be a reading of Gehrig's famous speech, delivered to 61,808 fans at Yankee Stadium July 4, 1939.

"You know how I feel about the tradition of our sport,'' said Selig. "Ask me how many times I've watched Gary Cooper in 'The Pride of the Yankees.' At least 100 times. He was such a wonderful human being. To be struck down the way he was and gone in two short years - he was an indestructible player.''

How good was Gehrig? You often read and hear about the 1927 Yankees. Buffered by performance-enhancing hot dogs, Babe Ruth smashed a record 60 home runs that season. But did you know that Gehrig hit .373 with 47 homers and 175 RBIs?

Never missing a game, the Iron Horse kept going strong into the late 1930s. He felt weak at the end of the 1938 campaign and took a $3,000 pay cut for the following season.

When he arrived at spring training in 1939, Gehrig's strength was gone. One day he swung and missed on 19 consecutive batting practice pitches. Two weeks into the season, Gehrig came out of the lineup. He tried playing again in June but fell over catching a line drive in an exhibition game in Kansas City. He went to see Dr. Charles Mayo in Rochester, Minn., the next day and a week later was informed he had ALS."
