1. First baseman

Sports · Baseball Abbreviations

Defensive player stationed near first base, position number 3 on a scorecard, who catches throws from other infielders to record outs. The position suits tall players with good hands and is often filled by power hitters.

Example: The manager moved his veteran catcher to 1B to save his knees.

First basemen record more putouts than any other position because most infield outs end with a throw to first. Lou Gehrig and Albert Pujols are among the greatest at the position. In stat columns 1B means a single instead.

2. Single

Sports · Baseball Abbreviations

Hit on which the batter safely reaches first base. In stat columns 1B counts singles, the most common type of hit.

Example: The rally started with a 1B to left and a walk.

In stat tables, 1B, 2B and 3B count hits, while in a lineup or on a roster the same symbols name defensive positions. Ichiro Suzuki's 225 singles in 2004 are the modern single-season record. Singles count one base toward slugging percentage.
