5 Statcast storylines for '17 Nationals

March 31st, 2017

As the 2017 season begins, so does the third season of Statcast™, the state-of-the-art technology that has tracked every play in every Major League ballpark since Opening Day 2015. And with two full seasons of data now collected, plus advances in applying that data, Statcast™ is better than ever. New metrics, such as Catch Probability and Hit Probability, will provide a deeper layer of analysis and further our understanding of the game.
With that in mind, here are five Statcast™ facts to know about the Nationals heading into the 2017 season.
1. Going higher
From 2015-16, raised his average launch angle from 10.7 degrees to 16.8 degrees. That gain (6.1 degrees) was the third largest among the 142 players who put at least 250 balls in play in both seasons, helping Murphy hit a career-high 25 home runs, 11 more than he ever had before.
Largest increase in launch angle from 2015-16
Minimum 250 balls in play in both years

  1. : 6.4 degrees (5.4 to 11.8)
  2. : 6.3 degrees (8.2 to 14.5)
    3. Daniel Murphy: 6.1 degrees (10.7 to 16.8)
  3. : 5.6 degrees (6.1 to 11.7)
    5-T. Brad Miller: 4.6 degrees (8.4 to 13.0)
    5-T. : 4.6 degrees (15.8 to 20.4)

2. Filthy four-seamer
During his National League Cy Young Award-winning 2016 season, Max Scherzer averaged 95 mph with his four-seam fastball, ranking 10th among pitchers who threw at least 1,000 of them. Meanwhile, his four-seamer spin rate (2,550 rpm) dwarfed the MLB average (2,264) and ranked second behind only out of 97 pitchers who had at least 750 such pitches tracked. High-spin four-seamers tend to create more fly balls and missed swings, and in fact, Scherzer finished second among qualified MLB pitchers in strikeout rate and sixth in fly ball rate, succeeding up in the zone.

    3. Hunting highlights
    With the White Sox in 2016, led all outfielders by making 30 catches that Statcast™ classified as four- or five-star plays -- the most difficult classifications on the 1-to-5 scale. The star system is based on Catch Probability, which factors in the distance the outfielder has to travel and his "opportunity time," which runs from when the pitcher releases the ball to when it is projected to land.
    Most four- and five-star catches made, 2016
    1. Adam Eaton: 30
  3. : 24
  4. : 21
    4-T. : 20
    4-T. : 20

Eaton also fared well in terms of his throwing arm. He recorded 12 outfield assists in which his throw was clocked at 90 mph or harder, tying him with for second in the Majors, behind only Ender Inciarte (13). Five of those assists reached at least 95 mph, tying Eaton for the MLB lead with and .

5. Winning with weak contact
Despite a rate of 7.4 strikeouts per nine innings that ranked 52nd of 74 qualified pitchers, posted a 2.83 ERA last season. It helped that Roark excelled at inducing weak contact, with opponents averaging an exit velocity of only 86.4 mph when they put the ball in play. That was seventh lowest among 145 pitchers who allowed at least 250 balls in play.
