The Aaron Harang Streak That Won't End

I say "Aaron Harang" and you think...what?

Andre the Giant look-a-like?

League-average innings muncher?

Eight-team mercenary?

Active pitcher with the longest career without a playoff appearance?

Yes, Harang has donned a uniform for 13 summers and 352 starts without enjoying firsthand the pageantry of October. Although he has twice entered service for a playoff-bound squad -- first his rookie campaign and then his inaugural season in Cincinnati -- in neither case was he a sufficient staple of the rotation to eat playoff frames. Since then he has endured the Reds' lean years and successive one-year-or-less stints in San Diego, Los Angeles, Seattle, Queens and Atlanta, none of which hosted post-season contests.

This year, at 37, Harang has found work for $5 million before the good people of Philadelphia, or at least what few of them will deign to countenance Citizens Bank ballpark while the home nine kills time until 2019. His streak, so lovingly nurtured across 2,150 innings of regular season action, appears destined to flower further, in large part because Harang can be expected to Rototill innings while Phillies brass contemplate what they can secure in trade for closer Jonathan Papelbon.

The Hardball Times points out that Harang is sixth in baseball in games pitched since he became a regular in 2004, eighth in innings and 11th in strikeouts. That shouldn't obscure what a plug-average hurler he's been over his career. In fact, setting aside his two peak seasons of '06-'07, when he won 32 games with a 3.75 ERA, 24% better than average; consumed 466 innings; fanned four times as many batters as he walked; and added 11.2 wins to the Reds' standing; Harang has enjoyed just one season more than five percent above average and four seasons at least 8% worse.

Over the 13 years, Harang has earned 23 WAR, two-thirds of it in his three best seasons. In Atlanta last year, Harang kept the ball in the park unusually well en route to 204 thoroughly average innings. That is unlikely to occur in Philly's breadbasket ballpark. Don't be surprised if the giant Californian gives back a WAR or two in '15.

Then again, if he continues the third-starter act he reveled in last year, Aaron Harang could find himself trade-deadline bait, perhaps to a contender in need of veteran presence. That's about the only hope he has for the streak to end.

Your Team Needs to Strike Out More

Do a web search on "2014 strikeouts" and you will find a parade of articles postulating about a jump in Ks this year. 

"Seattle Mariners: Strikeout problem stalling offense"

"Where are all of the Johnny Cueto strikeouts coming from?"

"What's behind all those strikeouts for Joe Mauer?"

"Strikeouts galore for the 2014 Mets"

For the seventh consecutive year, the strikeout rate has risen in April, to more than one every five plate appearances. Roughly 16 batters whiff in an average nine-inning game.

Theorized reasons for this trend are myriad. Fastball velocity has risen over the years, from an average of 89.8 mph in 2008 to 91.4 mph this season, according to Beyond the Box Score. Chris Moran notes in this BTB article that 12 pitchers had averaged 94 mph in an April start last year. That number was 25 with half of April to go in 2014.

There are other factors as well. Batters are swinging more at balls outside the strike zone and less at pitches inside it. That may be due to improved catcher framing, which has become a subject of much more emphasis now that cameras are observing every pitch and recording the result. Analysis has discovered that catchers can alter a significant number of ball/strike calls in the course of a game because umps are more likely to call strikes on pitches caught by the catcher if he doesn't move to retrieve the throw.

From an aesthetic standpoint, most fans are not enamored of this development. Few people pay to see a lot of wind-making. From a strategic standpoint, it seems obvious that strikeouts are a negative event for the team at bat -- after all, they are outs. But in a more general sense, the evidence suggests that strikeouts are very necessary evils.

In fact, strikeouts are often a tradeoff. Batters who swing hard and wait for their pitch -- i.e., pass on pitches they don't like even if they're in the strike zone -- tend to whiff frequently. But that strategy yields more walks, fewer double plays and more home runs. 

New research from the Hardball Times illustrates the actual correlations between strikeouts and other events. As you can see below, batters who fan more get on base slightly less (OBP) but hit for more power (SLG, ISO), ground into fewer twin killings (GIDP) and have a slightly higher batting average when they do make contact (BABIP), presumably because they hit the ball harder. On balance it's a positive tradeoff; more whiffs correlate with better overall hitting (wOBA).

Individual K rate and offensive statistic regression analysis
Stat Correlation (R)
OBP -0.07
SLG 0.19
ISO 0.40
wOBA 0.10
GIDP -0.22
IFH -0.27
HR/FB 0.53
IFFB% -0.16
GB% -0.28
FB% 0.31
BABIP 0.08
BB% 0.28

Obviously there's a limit to that relationship; if every batter struck out there would be no OBP, SLG, HR or scoring at all. And Major League baseball may have reached that tipping point. Scoring has declined more or less steadily during the seven years that strikeouts have risen.

All this may be premature -- a blip on the season's radar. But as part of a larger trend, it's probably not. And that means more Ks and fewer Rs the rest of the way. You've been warned.
