Here at Metsmerized Online, we require a strict adherence to AP Style sports writing. The AP Style Guide is the quintessential authority on grammar style and sports verbiage, and was created and updated by Associated Press journalists to standardize sports writing.

Understanding and using AP Style is a must for any aspiring sports writer or journalist, and is taught as part of any college curriculum for journalism or a related course of study.

I have broken down this MMO Style Guide into two parts: AP Style baseball verbiage and an AP Style best practices.

AP Style Best Practices

Numbers
Proper uses: first inning, seventh-inning stretch, 10th inning; first base, second base, third base, first home run, 10th home run, first place, one RBI, 10 RBIs. The hitter went 1-for-3. The pitcher’s record is now 6-5. The final score was 1-0.

Innings Pitched
While 5.1 innings is perfectly acceptable, mathematically is means five and two-tenths innings. It’s best to use the fractional form 5 1/3 innings.

RBI or RBIs
For more than one run batted in, the abbreviation is RBIs. (Alonso led the majors with 127 RBIs)

Postseason vs. playoffs
The terms aren’t interchangeable. Postseason encompasses all the games after the regular season ends from the Wild Card round to the the World Series. Playoffs refers only to the first two rounds that determine the World Series opponents.

AL and NL championship series
Spell out “championship series” on first reference with the league abbreviations. It’s AL or NL championship series initially, then ALCS or NLCS on subsequent uses.

Titles
Italicize titles of movies, songs, books, magazines websites. Example: Metsmerized Online, New York Times, The Walking Dead, The Force Awakens, Stairway to Heaven.

Standings
Always write out first place or last place.

Ages
Use hyphens for ages. (a 6-year-old boy, an 8-year-old car, a 4-year-old house) Or you can express ages as follows: Bruce, 30, is a free agent after this season.

Rankings
Always abbreviate the word “number” in rankings. Write No. 1 draft pick, not number one draft pick. Examples: The Mets selected Chris Correa with their No. 6 overall selection.

Betting Odds
Use figures and a hyphen: The odds were 5-4, the Mets won despite 3-2 odds against them.

Awards
When naming awards, always capitalize the word Award.
Ex: Most Valuable Player Award not Most Valuable Player award. Cy Young Award, Rookie of the Year Award

Numbers Less Than 10
Spell out numbers less than 10 standing alone and in modifiers.

  • I’ll be there in five minutes.
  • He scored with two seconds left.
  • The game was called after four innings.
  • The two-minute warning.
