More Than You Probably Wanted to Know About First-Inning Scoring
Any new fans coming to major league baseball through this past weekend’s London Series between the Yankees and Red Sox got a rather distorted sense of the game’s scoring and temporal norms, particularly in the first inning of each contest. In Saturday’s series opener, each team sent 10 batters to the plate, scored six runs, and chased the other team’s starting pitcher (New York’s Masahiro Tanaka and Boston’s Rick Porcello). The 12-run, 58-minute inning was just the opening salvo of a slugfest that seemed to be imported straight from Coors Field, a 17-13 slog that took four hours and 42 minutes to play. Sunday’s game, won 12-8 by the Yankees, wasn’t quite as high scoring, but it did feature a four-run first inning by the Red Sox that clocked in around 26 minutes, not to mention a nine-run seventh inning by the Yankees in a game that lasted four hours and 24 minutes.
Though neither team in Saturday’s game came close to outdoing this year’s first-inning high score (10 runs by the Phillies on April 16 against the Mets), and the two teams fell short of the combined record of 16 runs most recently accomplished by the A’s (13) and Angels (3) on July 5, 1996, the rivals did make some history. According to STATS, this was the first time since June 23, 1989 (Blue Jays at A’s) and just the sixth time since 1912 that both teams scored at least six runs in the first inning. Via the Baseball-Reference Play Index, that game was one of just three since 1908 in which neither starter got out of the first inning after allowing at least six runs, with an August 4, 1948 game between the Red Sox and Browns, and an April 16, 1962 game between the Cardinals (not Bob Gibson’s best day) and Phillies being the others.
The Yankees’ big numbers in London helped them overtake the Twins for the major league lead in scoring (5.80 runs per game). While Saturday’s game was the second time in less than two weeks the team chased a former Cy Young winner in the first inning after clobbering him for six runs — they did so on June 19 against the Rays’ Blake Snell as well as Saturday against Porcello — they’re actually not the majors’ most prolific first-inning team. They entered Sunday ranked eighth in the majors with 0.62 first-inning runs per game, a per-nine rate of 5.56.
