Kimbrel's success this year adds to the accomplishment he achieved last year, when he became the first pitcher in Major League history to record at least 40 saves in each of his first three full seasons.
Kimbrel has successfully converted 90.7 percent of the 197 save opportunities he has had since the start of the 2011 season. His 178 saves during this span are 47 more than any other Major Leaguer over the same period.
