F/F SPOTLIGHT: Michael Brantley

A glance at the 10 hitters who have produced the most value in 5x5 leagues so far this season reveals some expected names. Mike Trout, Andrew McCutchen, Carlos Gomez, Paul Goldschmidt, Giancarlo Stanton, and Billy Hamilton make up 60% of that list, and each of them was taken early or at high prices in most drafts.

The player with the fifth-highest 5x5 YTD value in MLB might come as a surprise: Michael Brantley (LF, CLE).

His five-category output explains why his returns have been so high:

.316 BA, 15 HR, 65 RBI, 70 runs, 11 SB

Only four OF have posted 15+ HR and 10+ SB so far this season: Gomez, McCutchen, Trout, and Brantley.

Let’s take a deeper look at Brantley in an effort to see if his hot first half is legit.

 

Background

Brantley was drafted in the seventh round of the 2005 amateur draft at age 18 by the Milwaukee Brewers.  He is the son of former major leaguer Mickey Brantley.

Scouts liked his speed and strike zone judgment, but his lack of power limited his upside and his inconsistency on defense was a concern. He was viewed more as a fourth-OF type than an impact MLB regular early in his minor-league career.

At the end of the 2008 season, Brantley was traded from the Brewers to the Indians in the deal that sent C.C. Sabathia from the Indians to the Brewers.

 

Minor League History

Brantley did not crack many top prospect lists during his time through the minors. In fact, he barely made Baseball America’s list of MIL’s Top 30 prospects when he was in their system.

This may have been a blessing in disguise, as he was not rushed through the minors. He skipped High-A but had a full season’s worth of AB at both Double-A and Triple-A.

Here are the raw stats posted by Brantley during the parts of six seasons that he spent in the minors:

Year  Age  Level     AB   BA    HR  RBI  BB  K   SB  CS  OPS 
====  ===  ========  ===  ====  ==  ===  ==  ==  ==  ==  ====
2005   18  Rookie    173  .347   0   19  22  13  14   5  .802
2005   18  Rookie     34  .324   0    3   6   4   2   0  .807
2006   19  Low-A     360  .300   0   42  61  51  24   7  .741
2007   20  Low-A     218  .335   2   32  31  22  18   6  .853
2007   20  Double-A  187  .251   0   21  29  25  17   3  .647
2008   21  Double-A  420  .319   4   40  50  27  28   8  .793
2009   22  Triple-A  457  .267   6   37  59  48  46   5  .711
2010   23  Triple-A  273  .319   4   29  34  28  13   5  .820

A few things stand out about Brantley’s background:

  • He was consistently a .300 hitter in the low minors
  • He proved that he could make adjustments and solidified his high-BA profile by hitting .300 in his second stints in Double-A and Triple-A
  • He had more walks than strikeouts at every level in the minors
  • He was consistently an efficient basestealer
  • He only posted a .400+ Slg in two of his eight stints in the minors

 

MLB History

Brantley was called up to CLE in late 2009 and broke camp in 2010 with them. After going back-and-forth between Triple-A and CLE during the 2010 season, Brantley stuck with CLE starting in the 2011 season.

Year  AB   BA    HR  RBI  BB%  CT%  Eye   G/L/F     PX  Spd
====  ===  ====  ==  ===  ===  ===  ====  ========  ==  ===
2009  112  .313   0   11   7%  83%  0.42  47/26/27  31  108
2010  297  .246   3   22   7%  87%  0.58  48/20/32  50  120
2011  451  .266   7   46   7%  83%  0.45  49/20/31  82  111
2012  552  .288   6   60   9%  90%  0.95  49/23/29  75  108
2013  556  .284  10   73   7%  88%  0.60  47/23/30  72  108

An inability to loft the ball seemingly capped Brantley’s power ceiling, an observation confirmed by his consistently mediocre power skills.

Brantley’s elite batting eye in the minors did not initially carry over from the minors to MLB. That changed in 2012. That’s when his contact rate reached an elite level and his batting eye soared.

 

2014 Results

Let’s insert Brantley’s 2014 results into his MLB stats and skills line:

Year  AB   BA    HR  RBI  BB%  CT%  Eye   G/L/F     PX   Spd
====  ===  ====  ==  ===  ===  ===  ====  ========  ===  ===
2009  112  .313   0   11   7%  83%  0.42  47/26/27   31  108
2010  297  .246   3   22   7%  87%  0.58  48/20/32   50  120
2011  451  .266   7   46   7%  83%  0.45  49/20/31   82  111
2012  552  .288   6   60   9%  90%  0.95  49/23/29   75  108
2013  556  .284  10   73   7%  88%  0.60  47/23/30   72  108
2014  399  .316  15   65   8%  91%  0.94  46/27/27  113   88

The most noticeable change can be seen in Brantley’s big HR spike. It has been supported by a corresponding jump in PX, as well as a huge surge in hard contact and line drives:

Year  HctX  LD
====  ====  ===
2009    68  26%
2010    98  20%
2011   111  20%
2012   100  23%
2013    92  23%
2014   131  27%

Reports suggested that Brantley increased his training regimen in the off-season and added significant muscle.

He also has become much more proficient at hitting fastballs with authority.

Check out his production by pitch type in 2013, specifically his feeble ISO power against four-seamers and cutters (data provided by BrooksBaseball.net):

Now look at how he is mashing both four-seamers and cutters so far in 2014:

While Brantley is hitting the ball with more authority, he has been the beneficiary of a HR-per-flyball rate that is more than double the highest level he had previously shown:

Year  HR/F
====  ====
2009    0%
2010    4%
2011    6%
2012    4%
2013    7%
2014   15%

In more detail, Brantley’s HR/F rates have been extremely high against four-seamers and cutters compared to other pitches (data courtesy of BrooksBaseball.net):

Brantley’s HR/F against cutters has increased from 9% in 2013 to 20% in 2014. His HR/F against four-seamers has gone up from 3% in 2013 to nearly 11% so far in 2014.

It's clear that Brantley’s HR/F-fueled HR spike merits further analysis.  We will revisit that in a bit. 

However, his elite BA does not.  His .328 xBA is the highest in MLB and has been fueled by his elite 91% ct% and his surge in hard contact.

As Brantley’s power has blossomed, his speed skills have declined:

Year  SB  Spd
====  ==  ===
2009   4  108
2010  10  120
2011  13  111
2012  12  108
2013  17  108
2014  11   88

Adding more bulk to his frame has likely contributed to this dip.

Interestingly, this decline has not been noticeable in his SB results because he has become even more efficient on the basepaths. His SB success rate by year over the last three seasons:

Year  SB%
====  ===
2012  57%
2013  81%
2014  92%

Getting a green light on the basepaths is becoming increasingly difficult for Brantley, a fact that makes little sense given how efficient he is at stealing bases:

Year  SBO%
====  ====
2009   21%
2010   15%
2011   15%
2012   13%
2013   13%
2014   10%

It seems intuitive that the green light given to Brantley should increase given his surging and elite SB success rate. If he can tap into his previously strong speed skills again, that combination could help him show the 30+ SB upside he flashed in the high minors.

 

Batted Ball Distance

One of the best ways to validate a batter’s HR/F is to look at his batted ball distance. Given Brantley's seemingly inflated HR/F, let's complete that exercise on him.

The average batted ball distance among batters this season is 279.54 feet (data courtesy of BaseballHeatMaps.com).

Here is Brantley’s batted ball distance trend along with how it ranks among MLB batters:

Year  HR/F  Distance  MLB Rank
====  ====  ========  ========
2010    4%    270.28       282
2011    6%    266.13       265
2012    4%    269.80       227
2013    7%    276.45       187
2014   15%    281.62       126

It’s noticeable that Brantley’s batted ball distance has been steadily increasing over the last few seasons.

That said, the above data also shows that there are 125 batters this season with a higher batted ball distance than Brantley.  His mark is just slightly above the MLB-average level.

This suggests that his high HR/F has little chance of sticking. In fact, its decline has been evident so far in July:

Month  HR/F
=====  ====
Apr     17%
May     19%
Jun     17%
Jul     10%

As a hitter who hits a lot more groundballs and line drives than flyballs, Brantley’s likely continued HR/F decline makes it very probable that his HR output will decline significantly in the second half.

 

PITCHf/x Plate Discipline Metrics

Strong plate discipline is one of Brantley’s primary calling cards.

Brantley’s PITCHf/x plate discipline metrics bring to light a couple of interesting trends about his plate approach.

First, a couple of definitions:

  • Swing%: % of pitches a batter swings at (MLB average in 2013 = 46%)
  • Z-Swing%: % of pitches a batter swings at inside the strike zone (MLB average in 2013 = 63%)

Here are those plate discipline metric trends for Brantley during his career:

Year  Swing%  Z-Swing%
====  ======  ========
2009   33.8%     46.0%
2010   36.8%     48.3%
2011   37.9%     50.3%
2012   40.5%     57.1%
2013   41.7%     59.6%
2014   41.7%     60.7%

Brantley has started to put his pitch recognition to good use. He has increased his rate of swinging at pitches inside the strike zone for five consecutive seasons.  That increasing skill has helped Brantley make a lot more hard contact this year.

His higher rate of swinging at more pitches inside the strike zone has increased his hot zones significantly from 2013 to 2014 (data courtesy of ESPN.com):

Finally, let’s look at the location of Brantley’s batted balls to see if he’s a hitter who uses the entire field or not (data provided by Fangraphs.com):

The left-handed Brantley sprays flyballs all around the park.  With a continued increase of his batted ball distance, some of those long flyballs to center-field could start to leave the park. However, it’s clear that his HR power is generated entirely by pulling pitches as all of his HR have been to right field.  His lack of opposite-field power caps his overall power ceiling.

 

Conclusions

With firmly elite plate skills and increased aggressiveness at pitches thrown inside the strike zone, Brantley should continue to provide a high batting average and a lot of hard contact.

His efficiency on the basepaths makes him a near-lock for 15+ SB, with many more possible if his opportunities to steal bases increase.

What’s not likely to continue at its current pace is Brantley’s HR output. Even though he's hitting fastballs with more authority, his mediocre batted ball distance makes it unlikely that he can sustain his current 15% HR/F. He will need to find a way to loft the ball more to become a sustained HR threat.

At age 27, Brantley is entering the prime of his career and remains a strong hold in keeper leagues. View him as a multi-category contributor—especially in BA, SB, and runs—but not one who will maintain his current elite level of power.
