Press B to swing or use B and press Left Analog-stick Up.
To steal home easily, when you have a runner on third, press the Left Analog-stick towards the third base line. You are now playing as the runner. Take the biggest lead that you can. The third baseman will run for the base. Once you see this, you should have plenty of time to get back, no matter how big your lead. After you slide in safely, take a huge lead again. When you see the pitcher move to pick you off, break for home. Because of your huge lead, you should slide in safely. If timed correctly, you should be safe about 95%. Note: Tap A rapidly to run faster.
