“Strikeout-to-walk ratio”的意思、由来-开放百科全书

In baseball statistics, strikeout-to-walk ratio (K/BB) is a measure of a pitcher's ability to control pitches, calculated as strikeouts divided by bases on balls.

A hit by pitch is not counted statistically as a walk and therefore not counted in the strikeout-to-walk ratio.

The inverse of this calculation is the related statistic for hitters, walk-to-strikeout ratio (BB/K).

Leaders

Through 2018, the all-time career leaders were Chris Sale (5.31), Corey Kluber (5.14), and Tommy Bond (5.04).^[1]

The player with the highest single regular season K/BB ratio through 2018 was Minnesota Twins pitcher Phil Hughes in 2014, with a ratio of 11.62 (186 strikeouts and 16 walks).^[2] He is followed by Bret Saberhagen (11.00 in 1994) and Cliff Lee (10.28 in 2010).^[3] Despite pitching only 149 innings in 2016, Clayton Kershaw set a new record for K/BB ratio by striking out 172 batters while walking only 11 for a ratio of 15.6.

A pitcher who possesses a great K/BB ratio is usually a dominant power pitcher, such as Randy Johnson, Pedro Martínez, Curt Schilling, or Mariano Rivera. However, in 2005, Minnesota Twins starting pitcher Carlos Silva easily led the major leagues in K/BB ratio with 7.89:1, despite striking out only 71 batters over 188⅓ innings pitched; he walked only nine batters.^[4]
