※ 引述《abc12812 ()》之铭言：
: PA HR AVG OBP SLG OPS+ WAR
: Dansby Swanson 1697 40 .246 .317 .390 85 4.0
: Swanson当年被鲁蛇第一指名选进 不久后被交易到勇士
: 被当作是未来勇士基石而早早就升上大联盟
: 不过到目前为止 累积了三个完整球季的成绩只能说是普普通通
: 算是比杂鱼板凳好一些但低于平均的表现
: 以状元的标准来看 这样的成绩算及格吗?
: 还是当初太早升被rush到了?

用这篇文章回应一下，算是稍微帮天鹅哥平反一下。
稍微简述一下内容，
重点就是告诉你为什么认为他有很大的进步而且打出身价，里面用一种衡量方式，wOBA，
来衡量，这个指标算是衡量这颗球打出去成为全垒打或安打的期望值，算是衡量击
球技巧跟力量的指标。
Swanson连续几年都一直在进步，而且文章写的时候的2019超越了Harper, Goldschmidt,
Hoskins, 是Bellinger之外进步最多的。
自己认为：一个状元除了要打得好，以棒球这样长期培养的运动型态，能在大联盟等级持
续一直成长也是球员的价值所在吧？
底下附上最主要的论述段落：
Swanson is ...
Striking out less: 20.4 percent, down from 22.9 percent
Walking more: 9.3 percent, up from 8.3 percent
Hitting harder: 46 percent, up from 34 percent
Hitting fewer grounders: 39 percent, down from 44 percent
More importantly, when he hits the ball in the air (flies and liners), he's hi
tting it harder. In 2017-18, his hard-hit rate on balls in the air was just 40
percent. This year, it's up to 57 percent. It's where damage is found.
Those are all good things. But how do you combine them into one number?
The way we get to that is through Expected Weighted On-Base Average, which acc
ounts for quality of contact as well as amount of contact, in an attempt to re
move the effects of park and defense. (For example, when Swanson crushed a bal
l at 103.2 MPH and a 30 degree launch angle in the third inning on Sunday, we
give him credit for the fact that such a ball is a hit 80 percent of the time
and a homer 74 percent of the time, not that Ketel Marte tracked it down for a
n out in the deepest part of Chase Field.)
In 2017, Swanson's expected wOBA was .297, or in the 10th percentile. In '18,
it was .278, or in the sixth percentile. (The Major League average in '17-18 w
as .320.) So far in '19, Swanson is up to .373
