Through Sunday, Boston’s record is 30-13 on the regular season, which puts the team 10-1/2 games in front of second-place Baltimore and New York for the lead in the American League East. However, believe it or not, this only ties the second-best record to start a season to this point. In 2002, Boston also began the season at 30-13 through 22 May but, to that point of the season, the Red Sox were only one game in front of the second-place Yankees, who had started 31-16. Two days earlier, Boston had improved its fast start to 30-11 after thumping the Chicago White Sox 9-0 at Fenway Park behind Derek Lowe’s eight-inning masterpiece on the mound and home runs from Jason Varitek and Shea Hillenbrand, but had dropped the final two games of the series. Boston would go on finish at 93-69 in skipper Grady Little’s first year as manager but 10-1/2 games behind eventual division champion New York.
In 1946, Boston’s record after 43 games of play was an amazing 34-9, in part thanks to a team-record 15-game winning streak between 25 April and 10 May of that season, which put their record to that point at an unbelieveable 21-3. The Red Sox had gone on to win another 13 of 19 and put themselves seven games in front of second-place New York. Boston would finish the season at 104-50, the second-best record in team history behind the 1912 club that had won 105 games and the World Series, and easily won the American League pennant by 12 games over Detroit and 17 games over New York. In contrast, the team’s worst record after 43 games was 8-35 in 1932 on a club that would finish with 111 losses that season, a franchise record for futility.
