Boston's Aroldis Chapman sets MLB record for strikeouts as a reliever with his 1,364th K

Aroldis Chapman has become the major leagues’ career leader in strikeouts as a reliever, toppling a record that had stood for more than half a century. The Boston Red Sox’s 38-year-old Cuban left-hander fanned the Angels' Denzer Guzman for the 1,364th strikeout in Chapman’s 17-year career with seven teams. It broke the record long held by Hoyt Wilhelm, the Hall of Fame knuckleballer whose 21-year career ended back in 1972. The Red Sox celebrated Chapman’s achievement in their Angel Stadium clubhouse, showing a video retrospective of Chapman’s career to his younger teammates.
