What can the Dodgers expect from Clayton Kershaw over the next seven years?

Per MLB.com, the Dodgers locked up Clayton Kershaw for seven years at $215 million earlier today. Dodgers president Stan Kasten is hopeful that the club will make the deal official by Friday morning. The news caused our eyes to jump to the horizon, wondering how the lefty will fare between now and 2020. But first, let’s put Kershaw in some historical context with what he’s already done.

Kershaw has led the Majors in ERA three years in a row, a feat only accomplished by Lefty Grove and Greg Maddux. In 2011, he became the youngest pitcher since Dwight Gooden to win the Cy Young award in the National League and already has two of them at the young age of 25.

Adjusting Kershaw’s ERA for league and park factors, we find that Kershaw’s 194 adjusted ERA in 2013 was the 41st-best dating all the way back to 1901 among starters who qualified for the ERA title. (Note: 100 is average.) Since 1930, it’s the 24th-best. If you limit the time frame to 1970-2013, Kershaw is one of only 11 pitchers to post an adjusted ERA of 190 or better.

Expanding the time frame back to 1901, Kershaw’s 2013 was the 10th-best by a left-handed starter. He is one of 12 left-handed pitchers to post an adjusted ERA of 190 or better in the last 112 years.

Now, back to his contemporaries. Combining 2011, 2012, and 2013, Kershaw’s aggregate 166 adjusted ERA is the best in baseball among starters who have tossed at least 500 combined innings. The next-best is Justin Verlander at 149, followed by Cliff Lee at 139. Among left-handers, only Kershaw, Lee, and Gio Gonzalez (126) have finished above 125 since 2011.

Kershaw’s deal makes him the most well-paid pitcher in baseball, ahead of Justin Verlander, who signed a seven-year, $180 million deal with the Tigers on March 29 last year.

How will he do going forward? It’s difficult to make comparisons with Kershaw since he is such a unique pitcher given his age, his resume, and the way he pitches. Since 1901, there have been 19 pitchers to post an adjusted ERA of 125 or better while throwing at least 1,000 innings before the age of 26. Only five – Walter Johnson (176), Kershaw (146), Tom Seaver (141), Roger Clemens (141), and Hal Newhouser (141) – were above 140. Kershaw, Newhouser, Noodles Hahn, and Gomez are the only lefties, and Newhouser was the most recent – he retired after the 1955 season.

Baseball Reference lists Kershaw’s ten-best comparables through the age of 25. They are Gary Nolan, Seaver, Jim Palmer, Vida Blue, Jim Maloney, Pedro Martinez, Dave McNally, Roger Clemens, Lefty Leifield, and Hal Schumacher. Nolan and Seaver get the highest similarity scores by a wide margin.

Nolan posted a 1.99 ERA in 1973 at the age of 24, but he missed time in August and September with neck and shoulder issues. He only threw 10 1/3 innings the next season due to arm issues, and missed all of 1974 as well. Though he was solid in 1975 and ’76 for the Reds, he quickly ran out of steam. He posted  6.09 ERA in 57 2/3 innings in ’77 at the age of 29 and then was out of baseball due to more arm and shoulder issues.

Seaver, of course, is a success story. Despite putting a strenuous workload on his arm throughout his career, topping 200 innings pitched in 16 of 20 seasons, he was able to pitch through his age-41 season. After his age-25 season, he had already won a Rookie of the Year award and a Cy Young award, but he wasn’t finished. He won two more Cy Youngs in 1973 and in ’75 at the ages of 28 and 30, respectively. Through age 32 – which is how old Kershaw will be in the final year of his deal – Seaver had a career 2.48 ERA (142 adjusted ERA) in nearly 3,000 innings.

Generally speaking, one would expect Kershaw to more or less match his output in the recent past through about his age-29 season before gradually tapering off. At the moment, we only have projections for 2014, but here’s what they look like from multiple sources:

  • Steamer: 192.0 IP, 3.08 ERA, 197 K, 52 BB
  • Oliver: 233.0 IP, 2.13 ERA, 237 K, 55 BB
  • ZiPS: 227.1 IP, 2.26 ERA, 233 K, 54 BB

By all three projection systems, Kershaw is expected to once again be the best starter in baseball in 2014. Starting from there, Kershaw should continue to be plenty productive as he wraps up the latter half of his 20’s. He has a lot of room to be worse and still provide enormous value to the Dodgers, as long as he can stay healthy.

Therein lies the rub. Kershaw must stay healthy. Projecting injuries is still at best an inexact science and a science best left to the experts. But as a general point, gambling seven years on Kershaw’s age 26 through 32 seasons is a lot better than gambling five years on Ryan Howard’s age 32 through 36 seasons, for example.

Jeff Zimmerman at FanGraphs has done tremendous research on injuries and predicted rather well for the 2013 season. In his formula, Zimmerman suggests that for every year older a pitcher gets, his likelihood of suffering an injury increases by one percent. If he makes a full season’s worth of starts (33), his odds diminish by three percent. If he suffers through an injury-plagued year, his odds increase by eight percent.

Over his six-year career, Kershaw has been almost perfectly healthy. He has never been on the disabled list, and has only missed time due to the AC joint in his right shoulder in 2009 (missed 13 games) and an impingement in his right hip last season (missed 10 games). Kershaw has also made exactly 33 starts three seasons in a row (he made 32 and 30 in the seasons prior, as well). So Kershaw’s odds of suffering an injury are pretty low going into 2014.

Taken all together, this is about as good of a gamble as the Dodgers could have hoped to have taken. The Dodgers are gambling on seven years which encompass the entirety of Kershaw’s prime and the contract barely takes him into his 30’s. Moreover, Kershaw has had a pristine bill of health through six seasons, especially since he has avoided elbow and shoulder injuries in his pitching arm. And, of course, he has been by far the best pitcher in baseball in recent years. There’s always the chance that this deal will go horribly wrong for the Dodgers, but you’ll be hard-pressed to find a more favorable situation with which to invest $215 million.

Kris Bryant exits game with sprained right ankle

The Cubs had a scare on Wednesday night when third baseman Kris Bryant left with an apparent ankle injury. In the bottom of the fifth inning, Nationals catcher Matt Wieters hit a pop up that veered just into foul territory near the third base bag. Bryant caught it but his momentum took him back into fair territory. In doing so, he stepped awkwardly on the third base bag and appeared to twist his ankle. Bryant needed the assistance of manager Joe Maddon and the team trainer to get off the field.

Bryant was diagnosed with a mild ankle sprain, CSN Chicago’s Patrick Mooney reports.

Bryant was 2-for-3 on the night before departing and being replaced by Jeimer Candelario. He’s now hitting .264/.395/.520 with 16 home runs and 32 RBI in 329 plate appearances. Needless to say, the 39-39 Cubs would see their playoff odds hurt immensely if Bryant were to miss a significant amount of time.

Hector Gomez reports Twins third baseman Miguel Sano will participate in the 2017 Home Run Derby, to be held in two weeks at Marlins Park in Miami. So far, Marlins outfielder Giancarlo Stanton is the only other confirmed participant.

Sano, 24, is having an outstanding season, batting .274/.375/.548 with 18 home runs and 53 RBI in 293 plate appearances. According to MLB’s Statcast, only Yankees outfielder Aaron Judge (96.7 MPH) has a higher average exit velocity than Sano (96.4 MPH).

Brian Dozier was the last member of the Twins to participate in the Home Run Derby. In 2014 at Target Field, Dozier failed to make it into the second round after hitting only two home runs. Justin Morneau is the only Twin to have ever won the Home Run Derby, as he beat Josh Hamilton 5-3 in the finals of the 2008 Derby at Yankee Stadium — although Hamilton out-homered him in total 35 to 22.
