Meaning of 大振り in boxing


I know 大振り is usually used in baseball to refer to a big swing of the bat, but
what is its meaning in boxing? I found it in the following sentence from a
manga in which a boxer is being encouraged by its trainer:

> お前のパンチは当たれば倒せるパンチなんだ！ただし勢いにのまれての **大振り** は御法度だ！コンビネーションから繋いでいけ。

I think it refers to a fast and strong punch, but why is it considered a
negative thing in this case? I would be grateful if you also could correct my
translation and explain the general meaning of the sentence. My attempt:

> Your punches can knock him down if you manage to hit him! But don't overdo
> it and avoid fast punches! Start from the combinations!




大振り is not fast. It refers to [a strong/heavy but slow
punch](http://streetfighter.wikia.com/wiki/Punch), which tends to give the
opponent a chance to dodge or counter-attack. Unlike jabs, 大振り cannot be
chained to a next movement, either. I think 大振り usually has a negative
connotation like this one. 勢いに飲まれる is an idiom meaning "to be overwhelmed",
"to lose one's cool in the heat".
