当然是直接跑向二垒，还用问吗？楼主千万不要反问反驳，问、驳就说明你明知故问！
～如何论述吃饭对人的重要性～

沒有所謂被迫進壘。唯一會被迫進壘的時候是當球落地，而且打者已經踩上一壘，才會有一壘跑者被迫進壘。如果一壘跑者維持在一壘上，打者尚未抵達一壘，那打者封殺出局。
當打者擊出高飛球時，一壘跑者通常會向前幾步判斷是否安打。如果判斷會接殺就會回去踩一壘壘包待命，看接殺後有沒有機會上二壘。
假設，這球飛的超高，還沒落下時打者已經上一壘，一壘跑者一樣只能等野手接殺後才能跑壘。
如果這時野手漏接，打者會判安全上壘，然後原一壘跑者才會被迫進壘，這時候就是看是外野手傳二壘快還是一壘跑者快。
以上是只有一壘跑者時。
如果非二出局，跑者在一二壘或是滿壘狀態。
規則還是一樣跑者必須等高飛球被接到才能進壘。但是這時候看狀況會有一條特殊規則。
如果打者打的是「內野高飛球」那 infield fly rule「內野高飛規則」會介入。裁判只要喊「infield fly」代表不管這球有沒有接到打者自動出局。跑者可以自由推進自擔風險。

給 貼吧包打聽：《Tag-up Rule》
Rule 7.08 (c) defines,
“He is tagged, when the ball is alive, while off his base. EXCEPTION: A batter-runner cannot be tagged out after overrunning or oversliding first base if he returns immediately to the base;”
Explanation of Rule 7.08 (c),
The baserunner will be tagged if the ball is still in the air and he is off the base. The runner has to wait in his first base until a fielder catches the ball. An exception to this case only implies when the baserunner immediately returns to his first base by oversliding or overrunning.
Rule 7.08 (d) defines,
“He fails to retouch his base after a fair or foul ball is legally caught before he, or his
base, is tagged by a fielder. He shall not be called out for failure to retouch his base
after the first following pitch, or any play or attempted play. This is an appeal play;”
Explanation of Rule 7.08 (d)
Any failure to reach the base, whether the ball is fair or foul is an official tag. And thus, he will be tagged by the fielder. However, when he retouches the base by any means or on a foul tip, he will not be called out. The opposing team may request an appeal to replay the move in case they want to as followed by Rule 7.08 (d) comment,
