Seven clubs -- the Dodgers, Angels, Brewers, Marlins, Pirates, Mets and Blue Jays -- were most active during the first month of the Season of the #Whiff campaign, which encourages fans to tweet every time they witness a strikeout on television or at the stadium during the regular season. Head & Shoulders pledged $40,000 during the month of April, and it raised $130,000 for RBI programs last year.
This year's campaign is expected to double last year's contribution, and Head & Shoulders will automatically donate an additional $1 to the RBI program for every strikeout this season. There were 405 games and 6,446 strikeouts in April, yielding another $6,446 in contributions for RBI.
