 Biographical Information
Harold Danielson was a catcher for six seasons. He started his professional career at the age of 16 with the 1945 Kansas City Blues, hitting .226. He finished one vote short for rookie of the year (American Association). In '46, he split time between the Binghamton Triplets, the Norfolk Tars (.208/~.283/.250 in 15 games) and the Joplin Miners (.203/~.259/.241 in 23 games). In 1947, Danielson batted .244 for the Twin Falls Cowboys and made the all-star team for the first time in his career. In 1948, Harold hit .309 with five home runs for Twin Falls. This time he was the top vote-getter in All-Star balloting for the Pioneer League. A year later, he homered a career-high six times for the Cowboys, drove in a career-best 63 and batted .268. With the Beaumont Exporters that year, he posted a .368 average. He finished his career with the Victoria Athletics and Salt Lake City Bees (.284/~.397/.333). in 1950.
 Two Grand Slams in One Game
Many good hitters have hit two or more home runs in a game, but grand slams? On August 6, 1949, Harold Danielson of the Twin Falls Cowboys did just that, clearing the bases twice. Since then, only eleven other players have achieved this feat, making this one of the most amazing and elite hitting feats in the game.
What makes this feat so wonderful, is that it is a team effort. One man may end up with all the glory (and RBIs), but without his teammates getting on, he just has two solo home runs. However, each player who achieved this feat deserves his place in history, as he has overcome the pressure not once but twice in one day to lead his team to victory.
