With his 100th strikeout on Sunday, Los Angeles Dodgers ace Clayton Kershaw broke the record for fewest walks (5) by a pitcher reaching the century mark. Kershaw finished the outing with 105 strikeouts versus just five walks, producing an impossibly high 22:1 K/BB ratio.

The K/BB record holder at the 100-strikeout pole had been Cliff Lee, who reached 100 against seven walks in 2010, needing until July 22 to get there. While Kershaw is on pace to shatter the season K:BB record, just one wobbly afternoon can torpedo the ratio. Of course, the Dodgers' three-time NL Cy Young Award winner doesn't have many bad outings.

Incidentally, the Dodgers are now visiting the Chicago Cubs, where one of the NL's other most dominant starters is looking to break a record. If the Cubs and Jake Arrieta beat the Dodgers on Tuesday, Chicago will have won 24 consecutive games started by the reigning NL Cy Young Award winner. Twenty-four! Run support helps but Arrieta hasn't required much at all during this streak.

So with the Dodgers and Cubs locked up and Kershaw and Arrieta both spinning sub-2.00 ERA seasons, we decided to look at some of the most mind-boggling starting pitcher stats from the last 50 years -- or since 1967. The year 1967 gives us a cool half-century to examine and splits the difference between (1) the MLB's expansion to a 162-game season in 1962 and (2) the AL's adoption of the designated hitter in 1973.

You may notice this Kershaw fellow appears below, as he's got a couple season streaks in progress.

Note: season figures listed below require a minimum of 162 innings pitched, which is the requisite number for eligibility for the individual pitching championship (lowest ERA). Numbers are courtesy STATS LLC. And unless otherwise indicated, statistics date back to the 1967 MLB season.
