Clayton Kershaw has made things difficult for opposing hitters throughout 2013.
Kershaw's history against the Cubs is stellar-- he's made four starts against them and allowed two runs or fewer in each.
But what about Kershaw and big-picture history?
With the help of Baseball-Reference.com, here’s a snapshot of where Kershaw stands in statistical history with what is likely six starts left in his season.
Kershaw enters with a 1.72 ERA. In the last 30 seasons, only two pitchers have qualified for the ERA title with an ERA that low at season’s end: Dwight Gooden (1.53 for the New York Mets in 1985) and Greg Maddux (1.56 in 1994 and 1.63 in 1995, both with the Atlanta Braves).
Kershaw's Last 10 Starts
It is extraordinarily rare for a left-handed pitcher to finish a season with that low an ERA. In baseball’s live ball era, the only one to do so was Hall-of-Famer Carl Hubbell, who had a 1.66 ERA for the 1933 New York Giants. The last before him was Rube Marquard, who posted a 1.58 ERA for the 1916 Brooklyn Robins (who became the Dodgers).
Also rare: for a southpaw to finish with that good of an ERA relative to his league. Baseball-Reference tracks ERA+, which measures that, adjusting slightly for his primary ballpark.
Kershaw’s ERA+ is currently 207 (his ERA is 1.72, the NL ERA is 3.74). Only three lefties since 1900 have had an ERA+ that good, the last being Ron Guidry (208 for the 1978 New York Yankees). Only one of those three was a National Leaguer—Jack Pfiester for the 1907 Chicago Cubs (216).
Opponents are hitting .182 against Kershaw this season. The last ERA-title qualifying pitcher to finish a season with that low an opponents’ batting average was Pedro Martinez (.167) for the 2000 Boston Red Sox.
Lowest Opponents' OPS
The last lefthander to do so was a former Dodger, though only for a few moments: Sid Fernandez (who made two appearances for the 1983 team) held hitters to a .181 batting average for the 1985 Mets.
There have been six pitchers in the divisional era (since 1969) that finished a season with an opponents’ batting average that low. The only Dodgers pitcher among them was Hideo Nomo, whose was also .182 in his rookie season, 1995.
For those looking to make the inevitable comparison to Sandy Koufax, the Dodgers legendary lefty had one season with an opponents’ batting average that low, 1965, when opposing hitters batted .179 against him.
And if you prefer OPS to batting average, Kershaw’s currently stands at .495. Only three pitchers have held opposing hitters below .500 since Bob Gibson and Luis Tiant both did so in the Year of the Pitcher, 1968: Nolan Ryan (.496, 1981 Houston Astros), Maddux (.482, 1995 Braves), and Martinez (.473, 2000 Red Sox).
Kershaw currently has 188 strikeouts and it seems inevitable he’ll reach 200, perhaps as soon as tonight.
He would become the third Dodgers pitcher to record at least four straight seasons with 200 or more strikeouts, joining Koufax (six straight from 1961 to 1966) and Don Drysdale (four straight from 1962 to 1965).
Lastly, perhaps it’s wishful thinking, but Kershaw enters tonight with a 16-inning scoreless streak. If he throws seven scoreless innings of each of his next six starts, he’ll match Don Drysdale for the second-longest scoreless streak in major-league history.
And he would be one inning shy of Orel Hershiser’s record streak. That streak began 25 years ago Friday.
