Los Angeles Dodgers pitcher Clayton Kershaw posted the best single-month WHIP by any starting pitcher (minimum five starts) since 1913, recording a sterling 0.52 mark over his six starts in May, per MLB Stat of the Day on Twitter.

Well on his way to a fourth Cy Young Award, the 28-year-old lefty went 5-0 with a 0.91 ERA in May, allowing just five runs (all earned) on 24 hits and two walks in 49.2 innings while striking out 65 batters.

Also impressive in April, Kershaw now owns a 7-1 record, 1.56 ERA and 0.65 WHIP for the season, with 105 strikeouts and just five walks in 86.2 innings (11 starts). He’s gone at least seven innings in every outing and has recorded double-digit strikeouts in seven of his last eight.

During his most recent start, against the New York Mets on Sunday, Kershaw became the first pitcher since 1900 to have five or fewer walks at the time he recorded his 100th strikeout in a season, per Elias Sports Bureau (via SportsCenter on Twitter). 

He also set a record for the most strikeouts (65) in a month featuring five or fewer walks and became just the fourth pitcher to record both a sub-1.00 ERA and 65-plus strikeouts in a calendar month, joining Randy Johnson (June 1997), Roger Clemens (August 1998) and Pedro Martinez (September 1999), per Elias (via ESPN.com).
