One of the more surprising, refreshing, and little-appreciated aspects of the Yankees’ solid season has been the team’s base running. We usually do not spend time talking about Yankee teams and base running because…well…in recent years it has not been good. From 2010 to 2016, the Yankees posted a negative BRR (base running runs, which is the runs better than average a team is at a certain advancement opportunity, with zero representing average) in four of those seasons, including every season from 2014-2016. Take a look at the chart below:

In other words, the Yankees have done a poor job in recent years at taking advantage of opportunities to take the extra base (making it to second successfully on a passed ball, going first to third on a hit to the outfield, etc). This is likely largely due to having older players who simply do not have the speed to do so. You could probably count on one hand a number of times you saw Carlos Beltran, Alex Rodriguez, or Mark Teixeira go from first to third or second to home on singles over the past three seasons.

This year, however, has been a much different story. The Yankees have collectively posted a BRR of 5.9, good for the eighth best mark in baseball (the San Francisco Giants rank first with a score of 9.6). The last time they ranked that high was 2013 when the team ranked ninth with a mark of 4.8. This year’s mark of 5.9 is the sum total of the individual scores given for the five different types of possible advancement by a base runner:

-SBR (Advancement on stolen bases): 2.10
-GAR (Advancement on balls hit on the ground to infielder): 1.18
-AAR (Advancement on balls hit in the air that are caught): 1.71
-HAR (Advancement on hits to the outfield): 1.59
-OAR (Advancement on other opportunities such as wild pitches and passed balls): -0.61

As you can see, the Yankees collectively are slightly better than average in four of the five potential advancement opportunities, while just a tick below average in taking advantage of passed balls and wild pitches (technically, balks are also included in “other”, but by rule the runner is allowed to move up a base, not by choice). The Bombers’ best baserunner in 2017 is unsurprisingly Brett Gardner, who currently boasts a personal BRR score of 3.2, good for 24th in all of baseball. Of the ten Yankees who have had at least 50 opportunities to advance a base or bases in any kind of manner (total base running opportunities), seven have posted scores above zero (again, with zero being average).

The 2017 Yankees being an overall good base running team not only passes the stat test, but it also passes the eye test. Here’s a good example of the kind of the thing that the stats say the Yankees are good at doing this season.

In the seventh inning of Thursday afternoon’s game against Detroit (in between all the brawling and bench clearings), the Yankees had team BRR leader Brett Gardner on first and Jacoby Ellsbury at third with nobody out while trailing by 6-4. Aaron Hicks hit a high fly ball to left which looked as though it was heading out for a three-run home run. Detroit’s Justin Upton leaped at the wall to rob Hicks of a long ball, but Ellsbury still tagged up from third to make it a one-run game.

Perhaps more importantly, Gardner did not get caught up in the fact that the ball may leave the ballpark but instead tagged up from first base and easily made it to second. Having the tying run at second with one out with the three and four place hitters in the lineup due up is a much better position than a runner at first with one out. And on cue, Gary Sanchez immediately followed with a ground ball single to center field that brought Gardner home with the tying run. So yes, while Sanchez gets credit for the RBI, Gardner also deserves a great deal of credit for the superb base running to get Sanchez in a situation where just a single could tie the game.

It feels nice when what the stats tell us and what our eyes/gut tell us actually coincide. In this instance, the two evaluation tools tell us that this Yankee team is quite good at taking the extra base when given the opportunity. As the regular season heads into the home stretch and playoff baseball approaches where outs are as precious as gold, this collective skill can help a team win games and ultimately series.

Aroldis Chapman threw an early contender for Pitching GIF of the First Half with this 90mph Slider to Brad Miller yesterday pic.twitter.com/OGFyVJEWmI

— Pitcher List (@ThePitcherList) April 5, 2017

Two things about this particular pitch: (1) As silly as Chapman made Miller look, that’s certainly much better than any of us would do in that spot; and (2) sliders from Chapman like that one will be a major factor in his continued success in the coming years.

Obviously, Chapman (who turned 29 in February) has made his living off his other-worldly fastball while mixing in his slider and changeup to keep hitters off balance. His secondary offerings—even if they are not executed perfectly—can make hitters look foolish since they typically are gearing up for 100 mph+.

However, the left-hander’s slider has been an elite pitch in its own right over his career. From 2010–16, opposing batters hit just .100 (24-239) with a .059 ISO against Chapman’s slider, which he threw a little over 16 percent of the time during that span. Batters aren’t hitting poorly against the offering just because they’re getting fooled by not getting the fastball; the pitch is also thrown hard (87.6 mph average in his career) and with some serious movement. Just take a look at the average horizontal movement of his slider for each month of his big league career.

Note: The lower the number, the more movement a pitch has

(By the way- see that little dot in the lower right hand corner of the chart just above 2017? That was the slider he threw to Miller. It moved 11.26 inches away from him. That’s absurd.)

Chapman’s slider is so good, in fact, that it compares favorably to the one owned by teammate CC Sabathia. Sabathia’s slider—which has long been considered one of his best offerings—also sits in that -2.5 to -7.5 inch range of horizontal movement. Even as Sabathia has lost velocity, he has gotten his slider to move even more, which helped him post the second highest soft contact percentage amongst all starting pitchers last season. While this is only one case, it does suggest one can survive a drop in velocity if one has great secondary pitches in the arsenal.

Of course, Chapman is not going to maintain his fastball velocity forever. It also remains to be seen whether his slider will lose its effectiveness once he does start experiencing a drop in velocity. No one knows for sure when it will begin to show signs of decreasing, but when it does, there is still reason to believe Chapman will still be an elite reliever because of his slider. Until that day comes, however, let’s just continue to enjoy highlights like the one above (sorry Brad) and hope that Chapman pushes off that day for a long time.

This particular story is an example of the latter type.

Over the past several seasons, Yankee fans have complained ad nauseam about the team’s inability to manufacture runs. In particular, the apparent inability to bring home runners from third.

Indeed, fans can trust what they see with their eyes in this instance. Over the past five seasons, the stats show that the Yankees have not done well at all with chasing in runners from third. The following chart shows the team success rate over the past five seasons with that particular task (I only factored in players who had over 300 total plate appearances in each season since those are theoretically a team’s best hitters, which usually was between 8 and 10 players each year).

In that five year span, the Yankees have ranked in the bottom half in the league in runs scored three times (16th in 2013, 20th in 2014, and 22nd last season), though they did rank second in both 2012 and 2015.

Now here is the good news: new Yankee Matt Holliday can help his new club fix this problem.

Holliday, 37, has been outstanding in getting runners in from third in his career. Over the past five seasons, the veteran has driven in the runner from third in 44.7 percent of his chances (or nearly ten percentage points higher than the Yankees as a team have averaged over that same span). The chart below breaks down how his success rate breaks down over each season:

Holliday’s 48.5 percent success rate in such situations in 2016 ranked 14th in baseball among the 258 players who received at least 300 at-bats. The highest ranked Yankee in 2016 was Starlin Castro, who checked in with a 41.7 percent rate (73rd). No other Yankee ranked in the top 100.

What does this mean in tangible terms? For one thing, it speaks to Holliday’s approach as a hitter. He’s never been a high strikeout guy (16.4 percent strikeout rate for his career, 16.9 percent over the past five seasons) and he puts the ball in play often and all over the field. His style is much different than what we have seen in the Bronx over the past several years when opposing teams shifted heavily in all situations against the likes of Brian McCann and Mark Teixeira.

Holliday’s all-fields/high contact approach seems to make him ideal at situations where any kind of ball in play equals a run. So even if Holliday this season drops down to his average success rate of 44.7 percent over the past five seasons, this important skill should be a big boost to the Yankees’ offense in 2017.
