One of the things that helped Bill Haas get over the hump this weekend in our nation’s capital was his splendid iron play. Haas, a top-10 finisher six other times this season on the PGA Tour, claimed his first TOUR win of 2013 on Sunday with a three-stroke victory at the AT&T National. Haas led the field with 25 birdies and also tied for fourth in greens in regulation (GIR), hitting more than 76 percent of his greens. For the year, Haas ranks 9th on TOUR in GIR at 69.02%, and is second in GIR from 150-175 yards (73.8%) and seventh from 200-plus yards (53.9%). Those numbers alone speak to his iron efficiency.

　　本赛季比尔-哈斯有6场美巡赛的前十完成。精湛的铁杆技术帮助比尔-哈斯取得了AT&T全美锦标赛的冠军。四轮比赛他一共抓下了25只小鸟，上果岭率76%(greens in regulation ，GIR)，排名并列第四。整个赛季他的上果岭率为69.02%，排名第9;150-175码间的上果岭率为73.8%，排名第2;200码以上的上果岭为53.9%，排名第7。这些数字再一次证明了他铁杆之精准。

　　What makes Haas such a good ball-striker — not just with his irons, but with all his clubs — is his ability to transfer his weight forward onto his left side during the transition phase of his swing. By the time Haas starts down from the top, his center of gravity has already shifted forward of the ball and most of his weight is on his left leg. Coupled with a very forward ball position, this is what allows Haas to launch his long irons on a higher trajectory, so the ball lands softer.

　　令哈斯成为优秀击球手的原因不仅仅是他的铁杆，而是他所有的球杆。在挥杆运动时，他能够提前将重量转移到身体左侧。当他上杆至顶端开始释放时，他的重心就已经转到了球的前面，他大部分的身体质量被移到了左腿上。再加上一个非常靠前的球位，哈斯就能用长铁将球打出一个更高的弹道，这样球在落地时会更柔软。

　　Ball position is a critical element to getting more distance and height from your long irons. Most amateurs make the mistake of playing the ball too far back in their stance, with their head over the ball. This forces them to hang back and try to help the ball up in the air. Usually, they end up hitting the ball thin or smothering it. The best iron players on TOUR, like Haas, play the ball well forward with their long irons, and then they go up and get it by aggressively shifting their weight onto their lead side on the downswing.

　　想要用铁杆将球打得远，打得高，球位是一个关键因素。很多业余球手错误地以为球应该在他们站位靠后的位置，头恰好悬在球的上方。这导致他们望而却步，通常情况下会导致打薄或者挥空。像哈斯这样最优秀的铁杆球员都会把球放在前面一些，然后他们能够具有攻击性地先将重量转移到主动的一侧，再把球“捞”起来。

　　If you want to hit high, majestic long irons like the pros do, than you need to commit to a more forward ball position and work on transferring your weight to your left side as fast as you can on the downswing. Here’s how to do it:

　　如果你想像职业球员一样用长铁杆击出高弹道的球，不妨尝试将球的位置稍微放前一些，然后努力练习在下杆的瞬间，尽量快地将重量转移到左侧。以下是具体的步骤：

　　Step 1: Position the ball inside your left heel (at least two balls forward of center in your stance) and assume a shoulder-width stance. Tilt your spine to the right so that your left shoulder is higher than your right and your head is behind the ball.

　　1：站姿与肩同宽，球的位置在左脚踝内(站姿中线前至少两个球的位置)，将脊柱向右倾斜，这样你的左肩就要比右肩高一些，头就在球的后方。

　　Step 2: Initiate the downswing by laterally moving your left hip and knee toward the target, so that they’re directly over your left ankle. This lateral bump brings the low point of your swing forward so that you can hit down on the ball with the club’s true loft.

　　2：通过超目标方向横向移动左臀和左膝来启动下杆。这样击球时左臀和左膝会直接处于左踝上方，会让你挥杆的最低点提前，这样你就能用球杆的真正杆面倾角接触白球。

　　Step 3: As you shift forward, maintain a swing direction that’s slightly to the right, or in to out. You still want to hit down on the ball, but try to brush or bruise the turf; don’t dig.

　　3：当你提前转动时，挥杆的方向略微向右，或者说由内向外。可能你仍然想打出球，但试试扫草坪，不过不是挖它。
