Ian Kinsler’s Historically Great Season at Second Base

In baseball, it may not be possible to have too much of a good thing when it comes to quantity of elite-level players. The sport is, almost by definition, at its best when great players face off against one another. If there’s a problem with a strong collection of elite talent, though, it’s that truly great players can get overlooked. It’s hard to distinguish oneself when surrounded by an array of other distinguished performances.

A look at the WAR leaderboard from the American League this past season reveals that four second basemen finished among the top 11 overall performers in the league by this metric.

We know MVP finalist Jose Altuve was outstanding and we know Robinson Cano had an absolutely tremendous season in Seattle. Slightly less heralded was the overall performance of the Twins’ Brian Dozier, although his 28 homers in the second half still garnered him plenty of attention. But what about the fourth second baseman on the list? Did we pay enough attention to Ian Kinsler this year?

Here’s the thing about Kinsler: he’s not just one of the second basemen on that list of top AL performances this season, he’s the oldest one, too — and “old” second basemen aren’t supposed to be this good. Kinsler turned 34 in June and the list of second basemen ever to record season WAR totals this high at age 34 or later is remarkably small:

5+ WAR Seasons by 2B age 34+ Since 1945
Season Name Team WAR
2003 Bret Boone Mariners 7.4
2002 Jeff Kent Giants 6.7
1999 Randy Velarde – – – 6.1
1991 Lou Whitaker Tigers 6.1
2016 Ian Kinsler Tigers 5.8
1982 Joe Morgan Giants 5.2
1993 Tony Phillips Tigers 5.2
1957 Red Schoendienst – – – 5.1
1951 Eddie Stanky Giants 5.0

Those are the top old second-base performances since 1956. Expand the list further back in time and you find that the only other second basemen to record higher WAR totals than Kinsler in their age-34 season or later are Hall of Famers Eddie Collins, Charlie Gehringer, and Nap Lajoie (who did it twice).

(Full disclosure: Kinsler is just four months older than Robinson Cano. Although this was technically Kinsler’s age-34 season and just Cano’s age-33 season, it’s a rather trivial distinction. But we already know Cano is not only fantastic, but a potential future Hall of Famer – a likely one, even. We can and will rave about him another day.)

When the Tigers traded Prince Fielder to the Rangers for Kinsler after the 2013 season, it looked at the time like a swap of two declining players on long-term contracts. Unfortunately, that was very much the reality for Fielder, whose playing career ended this summer due to injuries. But Kinsler? He has thrived in Detroit. Although he’s been an above-average contributor with the bat ever since the trade, much of his value has come from his glove. This year, however, he broke out offensively with a .288/.348/.484 slash line and 28 home runs. Overall, he posted a 123 wRC+, which is tied with 2011 for the second-highest mark of his career.


What’s changed for Kinsler? How is he putting together some of his finest offensive performances in his mid-30s? One significant trend over the past two seasons has been the decline of his ground-ball rate:


Another way to visualize this improvement is by looking at Kinsler’s performance charted on a strike zone. Naturally, ground balls are more common on pitches down in the zone, but Kinsler is doing a better job of not rolling over those pitches. The chart on the left shows his rate of grounders/pitch from 2012-2014 and the chart on the right documents that same thing from this past summer:


But the most significant change for Kinsler this season was his power. Home-run rates soared across the league in 2016, so he isn’t particularly unique in this distinction. However, the league’s rate of homers per fly ball (HR/FB) made a 12% increase from 11.4% a year ago to 12.8% this past summer. Kinsler, on the other hand, saw a 150%(!) increase in his HR/FB rate from 5.0% in 2015 to a nearly league-average 12.5% this year. Clearly, his personal improvements in this department far exceeded the league’s collective improvement. The result was as many homers in 2016 (28) as he hit in his first two seasons with the Tigers combined (17 in 2014 and 11 in 2015).

There is an important caveat which accompanies the improvement in power: of the 60 players with 25 or more homers recorded by Statcast this season, Ian Kinsler’s average home-run distance doesn’t just rank near the bottom; it comes in dead last, at 381 feet. Kinsler’s average home-run distance in 2015? Also 381 feet. Overall, he did see an uptick in exit velocity from last year to this year (86.2 mph to 87.5 mph), but his 87.5 mph exit velocity was still tied for the 125th lowest among the 150 batters this season with a minimum of 300 batted-ball events. This makes it easy to imagine Kinsler will struggle to replicate his power surge next season. Additionally, he posted the highest strikeout rate of his career and lowest contact rate since his rookie season. Swapping contact for power is great when it works, but the increased lack of contact may become conspicuous if it’s not accompanied by a similarly extreme a power surge next season.

Despite that one note of caution, nothing can take away from Kinsler’s tremendous performance this season. After missing the playoffs for the second straight year, the Tigers will look to find a way to put themselves in position to win again and soon. The fact that Kinsler is only under contract for one more season — with an additional team option for 2018 — could make him an intriguing trade chip this winter. Given the unlikelihood that Kinsler will improve further during his age-35 season, his trade value may never be higher than it is right now and the Tigers may find a trade return that can help them beyond 2018. Under contract for just $11 million next year, Kinsler could be an excellent fit for a team in win-now mode with a current weakness at second base such as the Dodgers, Cardinals — or, depending on the direction they take this winter, the White Sox.

Does he pull the ball in the air more than normal? That would explain how he gets home runs with less distance since the fence is closer down the line than to center.

He is an extreme pull hitter on fly balls. In fact, Baseball-Reference says he has hit 11 home runs to center or right field – in his entire career.
