Can Los Angeles Dodgers pitcher Clayton Kershaw dominate in his 30s like he did in his 20s?
Kershaw turns 30 on March 19th. He enters the 2018 season (and his 30s) with 144 career wins and only 64 losses, a .692 winning percentage. Kershaw’s career in his 20s was one of the best in MLB history. Consider this:
- Kershaw is one of only 34 pitchers in baseball history to have 140 or more wins in his 20s.
- Kershaw’s .692 winning percentage is the second-best all-time of the 171 pitchers who won 100 or more games in their 20s. Whitey Ford was 105-40 (.724 winning percentage) in his 20s, the highest winning percentage in this stat.
Kershaw is one of three active pitchers who won 140 or more games in their 20s. C.C. Sabathia won 157 in his 20s, while Felix Hernandez won 143 in his 20s. (For the record, Sabathia has won 80 in his 30s; Hernandez has won 17.)
As I stated in the opening paragraph, the question will be can Kershaw, now age 30, match the success he had in his 20s. Can he reach 200 wins? How about 250? Or 300?
Looking at the 31 non-active pitchers who reached 140 or more wins in their 20s, it’s interesting to note that not all had success in their 30s. In fact, nine of the 31 did not reach 200 career wins after posting 140+ before hitting their 30s. Others flourished in their 30s… some even winning more games in their 30s than their 20s. For example, these pitchers with 140 or more wins in their 20s won more in their 30s than their 20s;
Pete Alexander (won 160 in his 20s; 213 in his 30s)
Roger Clemens (won 152 in his 20s; 202 in his 30s)
Greg Maddux (won 150 in his 20s; 205 in his 20s)
Tom Seaver (won 146 in his 20’s; 165 in his 30s)
There have been 11 pitchers who won 140+ in their 20s who won less than 40 games in their 30s. Unfortunately, some of these pitchers passed away during their baseball careers. For others, injury or other performance factors played a role in them not matching their win totals from their 20s. Those 11 pitchers are:
Dizzy Dean, 3 wins in his 30s… 147 wins in his 20s
Addie Joss, 5 wins in his 30s… 155 wins in his 20s
Wes Ferrell, 18 wins in his 30s… 175 wins in his 20s
Hal Newhouser, 22 wins in his 30s… 185 wins in his 20s
Ken Holtzman, 23 wins in his 30s… 151 wins in his 20s
Don Drysdale, 32 wins in his 30s… 177 wins in his 20s
Fernando Valenzuela, 32 wins in his 30s… 141 wins in his 20s
Chief Bender, 36 wins in his 30s… 176 wins in his 20s
Lefty Gomez, 36 wins in his 30s… 153 wins in his 20s
Dave McNally, 36 wins in his 30s… 148 wins in his 20s
Dwight Gooden, 37 wins in his 30s… 157 wins in his 20s
One final note: There are only two active pitchers under the age of 30 who have accumulated 100 or more wins. Rick Porcello sits at 117 career wins. He dies not turn 30 until after the end of the 2018 season. Madison Bumgarner has 104 career wins and doesn’t turn 30 until August 1, 2019. He certainly has an outside chance of reaching that 140 career wins in his 20s.
