If the player wishes to dribble after a pivot, the ball must be out of his hand before the pivot foot is raised off the floor. If the player raises his pivot off the floor, he must pass or attempt a field goal before the foot is returned to the floor. 「如果球員在轉身之後想要運球,球必須在中樞腳離開地面之前離開他的手。如果球員的中樞腳已經離開地面,他必須在這隻腳重新落地之前將球傳出或者嘗試投籃。」 If he fails to follow these guidelines, he has committed a traveling violation. 如果他未能遵守以上原則,即發生走步違例。
FIBA規則中25.2節實際是分別對兩種情況做出的判定。但是在對小加這個範例判定上並沒有異議。 25.2節的大前提是「在比賽場地上接住一個活球的隊員確立中樞腳」(Establishing a pivot foot by a player who catches a live ball on the playing court)。
25.2.1節直接確立哪兩種情況下的中樞腳判定。分別對應「站立接球後」(While standing with both feet on the floor)的中樞腳判例,和「移動接球後」(While moving)的中樞腳判例。 25.2.2節用於分析這兩種判例,即「While standing with both feet on the floor」和「While moving」,另有「停步時無軸心腳(While coming to a stop when neither foot is the pivot foot)」的補充。
小加索爾接球時處於邊線內10英尺左右的位置,經過4次運球,近2秒時間才移動到了提問者第一張圖所在位置,所以他的情況當然不適用於「While standing with both feet on the floor」。 因為他根本就是moving過去的,而不是站在那個位置接的球。
沒走步,原因如下: 可以抬起中樞腳去投籃,但在球離手前中樞腳不得落回地面。
RULE NO. 10-VIOLATIONS AND PENALTIES Section XIV-Traveling g. If a player, with the ball in his possession, raises his pivot foot off the floor, he must pass or shoot before his pivot foot returns to the floor. If he drops the ball while in the air, he may not be the first to touch the ball.
