Welcome to the Bloomberg Sports Blog
Welcome to the debut of the Bloomberg Sports blog, a partner of Major
League Baseball and part of the MLBlogs network. Starting today and
continuing through the final pitch of the World Series, we’ll cover all
the hot topics in baseball and fantasy baseball, with the help of Bloomberg Sports’ proprietary software and analytics.
Say you’re preparing for your fantasy draft, targeting Joe Mauer as
your starting catcher. Bloomberg Sports’ Draft Kit includes rankings
for every player, called B-Rank. Using B-Rank, you’ll see how Mauer
stacks up against all other players.
You can then delve deeper. Say you want to eyeball a player’s value against others at the
same position, then make an informed decision on when in the draft to
grab him. Bloomberg Sports’ Scarcity vs. Demand graph shows you a graph
of the top 10 players at that position, how high each one should be
drafted, and where the best values might lie. If you’re scouting Mauer,
the yellow dot representing the Twins catcher will show up far above
all other catchers, a sign of his unique value.
Now let’s explore a player whose ranking isn’t as obvious, newly signed Arizona Diamondbacks first baseman Adam LaRoche.
According to B-Rank, LaRoche rates 17th among all major league first basemen for projected 2010 fantasy value, given standard 5×5 criteria. In a 12-team National League-only league or deep mixed league, LaRoche would be worthy of a starting job. He would project as a mid-to-late round pick, in a cluster with decent but unspectacular players like the Dodgers’ James Loney in the Scarcity vs. Demand graph.
Using our Spider Chart, you can see that LaRoche derives most of his value from counting stats such as home runs, runs scored and RBI, with less value derived from his batting average and virtually none from stolen bases. At a glance, you can spot LaRoche’s 2009 totals in every category against other players major league-wide, or just other first basemen. His 25 home runs, for instance, placed just below the average of 27 homers for qualifying MLB starters at first base, well below the MLB-leading total of 47 at that position.
Using the Scatterplot tool, you can
compare LaRoche’s value across two categories at once, measured against the top 10 players
in that two-category combination — home runs and batting average, RBI and stolen bases, and other customizable combinations.
The Bloomberg Sports team of writers will then dig up more nuggets of information for your perusal. Say you’re satisfied with LaRoche as a low-end starter for your team. But you’re concerned about his large splits – for his career, LaRoche has batted .252/.326/.447 (AVG/OBP/SLG) in the first half, with a much stronger .300/.363/.546 line in the second half. You might then view LaRoche as someone to target in trade around the All-Star break, rather than spending a pick on him in your draft or auction.
Ascertaining why a player fares better in one half of the season compared to the other can be a tough task. Often it’s the equivalent of flipping a coin and landing on heads five times in a row: a rare but possible occurrence that’s based simply on random chance.
Occasionally there might be other reasons. Some players perform better in warmer weather, or at least hit for more power in warmer weather. In Pittsburgh and even Atlanta, where he played the bulk of his first six major league seasons, LaRoche’s power indicators jumped across the board as temperatures rose. For his career, he’s hit home runs on 12.7% of his flyballs in March and April, 11.7% in May and 12.8% in June. That number soars to 18.9% in July and 17.0% in August, making LaRoche a greater power threat in the warmer summer months. In sweltering Phoenix, LaRoche can expect average highs of 84 in April and 93 in May. By June, the Diamondbacks will likely close their retractable roof for most games, with average temperatures near or over 100 for the final four months of the season. The closed roof would in turn create cooler home playing conditions as the season wore on.
We can’t say for certain if LaRoche’s superior performance and higher power output in the second half is the result of warmer weather – it could simply be another way to look at the same random streak of better second-half performances. If it is weather-related, though, playing in Arizona, and facing warmer-weather opponents more often in the NL West, could portend a hotter-than-usual start for LaRoche.
LaRoche could also get a boost from more favorable ballpark effects. Chase Field consistently ranks as one of the most favorable stadiums in baseball for hitters – second behind Coors Field in run factor last season and second behind Rangers Ballpark in Arlington. Chase’s configuration also plays to one of LaRoche’s greatest strengths as a hitter. LaRoche has averaged 37.5 doubles per year in the past four seasons, ranking him among the league leaders in that category. Only Fenway Park, with its shallow, towering Green Monster, has yielded a higher doubles effect in the past two seasons than Chase Field.
Once the season starts, Bloomberg Sports’ In-Season tools let you
track a player’s day-today performance down to the finest details. Say
you drafted LaRoche and he got off to another slow start, hotter weather and all. The Visual Benchmark
tool lets you plot how LaRoche’s three home runs through the first 40
games of the season compare to different cohorts: other players at his
position, other National League players at his position, or the league
average for all players.
Still not sure if you should hold or cut bait? Using the
Competitive Factors tool, you can see how LaRoche’s new team stacks up
against the rest of the league. Last year, the Diamondbacks ranked 19th in batting average (20th in MLB in runs scored), despite their hitter-friendly home park. If Chris Young, Stephen Drew and other talented but erratic teammates don’t fare better in 2010, that suppresses LaRoche’s potential to score
and drive in runs – meaning you might want to consider a different option at first base.
