St Louis Cardinals 2nd baseman
If you're talking about the person who tags you to get you out is 1st baseman 2nd baseman and 3rd baseman.
The Yankee's second baseman is Robinson Cano.
1st Baseman 2nd Baseman 3rd Baseman Pitcher Catcher Short Stop Batter
You have your catcher, pitcher, 1st baseman, 2nd baseman, short stop, 3rd baseman, right fielder (behind 1st), left fielder (behind 3rd), and you center fielder (behind 2nd)
Lets say there is a man on first base, and the batter gets an infield ground hit that is picked off by the shortstop. The shortstop throws the ball to the 2nd baseman who steps on 2nd base before the runner a at 1st can reach it. This is a force out as the 2nd baseman does not have to tag the incoming runner. If the shortstop caught the ball before the ball hit the ground and can throw the ball to the 1st baseman before the runner at 1st can get back and put his foot on the bag, then that would also would be a force out.
