Defensive spectrum

Last updated

In sabermetrics, the defensive spectrum is a graphical representation of the positions on a baseball field, arranged from the easiest (such as first base and the outfield corners) on the left to the hardest (such as the catcher and middle infielders) on the right.

The spectrum

The defensive spectrum is: [1] [2]

Designated hitter – First baseman – Left fielder – Right fielder – Third baseman – Center fielder – Second baseman – Shortstop – Catcher – Pitcher

In some versions of the defensive spectrum, pitcher and catcher are not included, since the demands of those positions are so specialized as to be inapplicable to players at other positions. [1] [3] The designated hitter is sometimes omitted as well, since that player is technically not part of the "defense" at all.[ citation needed ]

As an example of the concept in action, players who are drafted by Major League Baseball teams as shortstops are far more likely to ultimately end up at a different position than players who are drafted as first basemen. [4]

History

Like many original sabermetric concepts, the idea of a defensive spectrum was first introduced by Bill James in his Baseball Abstract series of books during the 1980s. [2] The basic premise of the spectrum is that positions on the right side of the spectrum are more difficult than the positions on the left side. Therefore, the positions are easier to fill as one goes left on the spectrum, since the physical demands are less. [5] A corollary to this is that, since defensive skill is at less of a premium on the left side, players at those positions must provide more offense than those on the right. [2] [3] Another corollary is that players can generally move from right to left along the spectrum successfully during their careers (especially as they age), [6] but moving a player from left to right is quite risky. [1] [7]

Historical shifts

A retrospective analysis of the 140-year history of baseball shows that the defensive spectrum shifted once. In the late 19th century and early 20th century, third base was generally considered to be more challenging than second base. This was because the double play was relatively uncommon in this period; [1] thus, the third baseman, who had to field hard hit grounders and throw the ball 120 feet to first base, had a far more challenging job than the second baseman, who threw the ball 70 feet at most. Frequent bunting also meant that the third baseman would be challenged defensively more often. [8]

As a result, there were far more good hitters at second base than third (including players such as Nap Lajoie and Rogers Hornsby), and the defensive spectrum was:

First baseman – Left fielder – Right fielder – Second baseman – Center fielder – Third baseman – Shortstop – Catcher – Pitcher

However, by the 1920s and 1930s, the defensive spectrum began to shift. Double plays were steadily becoming more common, increasing the defensive responsibilities of the second baseman. Offense correspondingly became more important at third base. One of the new breed of third basemen was Harlond Clift of the St. Louis Browns, who became the first third baseman to hit 30 home runs. [9] By 1945, second base was firmly established as a more important position defensively than third base.

In the early 2020s, due in part to increasing numbers of strikeouts and use of infield shifts, teams have become increasingly willing to move players to more difficult positions (rightward along the spectrum). [10] Players such as Ryan McMahon, Max Muncy, Travis Shaw, and Mike Moustakas have transitioned, either permanently or temporarily, from third base to second base as part of a trend of physically larger athletes being placed at the latter position.

In the sport of baseball, each of the nine players on a team is assigned a particular fielding position when it is their turn to play defense. Each position conventionally has an associated number, for use in scorekeeping by the official scorer: 1 (pitcher), 2 (catcher), 3, 4, 5, 6 (shortstop), 7, 8, and 9. Collectively, these positions are usually grouped into three groups: the outfield, the infield, and the battery. Traditionally, players within each group will often be more able to exchange positions easily ; however, the pitcher and catcher are highly specialized positions and rarely will play at other positions.

<span class="mw-page-title-main">Softball</span> Team ball sport

Softball is a game similar to baseball, and it is played with a larger ball on a smaller field and with only underhand pitches permitted. Softball is played competitively at club levels, the college level, and the professional level. The game was first created in 1887 in Chicago by George Hancock.

<span class="mw-page-title-main">Shortstop</span> Defense position in baseball and softball

Shortstop, abbreviated SS, is the baseball or softball fielding position between second and third base, which is considered to be among the most demanding defensive positions. Historically, the position was assigned to defensive specialists who were typically poor at batting and were often placed at the bottom of the batting order. Today, shortstops are often able to hit well and many are placed at the top of the lineup. In the numbering system used by scorers to record defensive plays, the shortstop is assigned the number 6.

<span class="mw-page-title-main">Error (baseball)</span> Baseball statistic

In baseball and softball statistics, an error is an act, in the judgment of the official scorer, of a fielder misplaying a ball in a manner that allows a batter or baserunner to advance one or more bases or allows a plate appearance to continue after the batter should have been put out. The term error is sometimes used to refer to the play during which an error was committed.

The Rawlings Gold Glove Award, usually referred to as simply the Gold Glove or Golden Glove, is the award given annually to the Major League Baseball (MLB) players judged to have exhibited superior individual fielding performances at each fielding position in both the National League (NL) and the American League (AL). The Gold Glove is widely considered one of the most prestigious defensive awards in baseball.

<span class="mw-page-title-main">Third baseman</span> Baseball position

A third baseman, abbreviated 3B, is the player in baseball or softball whose responsibility is to defend the area nearest to third base — the third of four bases a baserunner must touch in succession to score a run. In the scoring system used to record defensive plays, the third baseman is assigned the number 5.

<span class="mw-page-title-main">Second baseman</span> Baseball fielding position

In baseball and softball, second baseman, abbreviated 2B, is a fielding position in the infield, between second and first base. The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play. In addition, second basemen are usually right-handed; only four left-handed throwing players have ever played second base in Major League Baseball since 1950. In the numbering system used to record defensive plays, the second baseman is assigned the number 4.

<span class="mw-page-title-main">First baseman</span> Infield defensive position in baseball and softball

A first baseman, abbreviated 1B, is the player on a baseball or softball team who fields the area nearest first base, the first of four bases a baserunner must touch in succession to score a run. The first baseman is responsible for the majority of plays made at that base. In the numbering system used to record defensive plays, the first baseman is assigned the number 3.

<span class="mw-page-title-main">Baseball rules</span> Overview of the rules of baseball at different levels and in different countries

Throughout the history of baseball, the rules have frequently changed as the game continues to evolve. A few common rules most professional leagues have in common is that four balls is a base on balls, three strikes is a strikeout, and three outs end a half-inning.

<span class="mw-page-title-main">Right fielder</span> Defensive position in baseball

A right fielder, abbreviated RF, is the outfielder in baseball or softball who plays defense in right field. Right field is the area of the outfield to the right of a person standing at home plate and facing towards the pitcher's mound. In the numbering system used to record defensive plays, the right fielder is assigned the number 9.

A hit and run is a high risk, high reward offensive strategy used in baseball. It uses a stolen base attempt to try to place the defending infielders out of position for an attempted base hit.
