Earlier, we took a look at the young season’s most impeded home run so far, which is the home run that faced the most opposition from the game conditions at the time. All necessary data was recovered from the ESPN Home Run Tracker, which is among my most favorite of Internet resources. If we look at one extreme, then, it follows that we should look also at the other extreme, or else the matter will feel incomplete, and this is a website devoted to completeness. And so we now turn our attention to the home run that has gotten the biggest boost from the game conditions. Home runs like this are probably more interesting than home runs that remain home runs despite strong winds and cold conditions, because these might be identified as “lucky”.

In terms of impeded home runs, we had one dinger at -20 feet, and another dinger at -17 feet. So it was a close race, and the error bars probably overlap. Here, in terms of aided home runs, we have one dinger at +64 feet, and another dinger at +43 feet. That’s a much bigger difference, but there might still be some error-bar overlap, for reasons we’ll get into. Let’s look at the home run in question!

In the first game of a Tuesday doubleheader in Colorado, the Braves and Rockies played in a temperature that was measured at 23 degrees at first pitch. It’s hardly impossible to imagine temperatures that low — in some places temperatures are that low all of the time — but it’s hard to imagine playing baseball, and specifically hitting a baseball, when it’s below freezing out. Nevertheless, the Braves and Rockies played, and the Braves emerged victorious, having slammed a trio of dingers. That got my mental gears whirring.

Take an ordinary fly ball. At room temperature, it would have a given distance. In hotter conditions, it would fly farther. In colder conditions, it would fly less far. So I found it impressive that the Braves hit three home runs when it was around 23 degrees, and my initial thought was that the cold canceled out the effect of the altitude. From there, I started messing around on the ESPN Home Run Tracker, and I looked beyond Tuesday’s first game in Colorado. I started looking for the 2013 home run that has lost the most distance due to non-standard conditions.

The hard-throwing, 24-year-old Matt Harvey has quickly become a must watch when he toes the rubber for the Mets. Called up in late July of last year, Harvey and his blistering fastball (94.6 average velocity) currently sport a 31.3% strikeout rate and an ERA- of 25 — no, not 75, 25. In 2013, Harvey has made four starts, lasting at least seven innings in each appearance. He has only allowed one home run and a paltry 10 hits in 29 innings.

Harvey does feature a number of pitches, but he’s heavily reliant on his four-seam fastball, throwing that pitch 60% of the time. That ranks him fifth among all qualified pitchers in 2013. And that fastball has been deadly.

According to the PITCHf/x leader boards at Baseball Prospectus (powered by Brooks Baseball), Harvey has induced a .042 ISO (2nd best) and a .167 BA (3rd best) against when using his fastball. David Golebiewski from Baseball Analytics recently wrote about Harvey’s ability to win with the high fastball. The numbers were eye-popping. Harvey so far this year has induced whiffs on high fastballs 48.4% of the time, and he’s throwing upstairs over 50% of the time.

I was curious how this compared to others this year and in previous years. So I did some digging.

Declarative baseball statements on April 24 surely don’t have much of a track record, but let me be clear: this is not, and will not be, the Year of the Rookie. To pretend as though 2013 will hold a candle to 2012 in terms of on-field rookie impact would be a lie. But, our series forges on regardless, and in even in down rookie seasons like this one, there are still phenoms (Jose Fernandez) and there are still great stories (Jim Henderson). Though neither of those solid April performers cracked today’s list.

One thing we have noticed is very strange: the American League offers nothing to chew on. This list contains four names and all are National Leaguers, and frankly, the NL would offer at least 8 rookies before we’d be forced to consider a player from the AL. So, it’s a promise, this list is not biased in favor of the Senior Circuit. It’s just that we’re not yet too excited about Pedro Florimon or T.J. McFarland (your current AL ROY race). Onto this week’s edition…

1. Matt Adams, 1B/PH, St. Louis Cardinals

The key I see from Adams this season is the ability to make adjustments in the middle of an at-bat. Adams has a SwStr% more than five percent above league average, but the bulk of these are occurring early in an at-bat, and oftentimes we’ll see Adams adjust against the same pitch a few pitches later. Let’s track three great examples with the help of the Brooks Baseball Pitch F/X tool.

Yes, well obviously Roberto Hernandez is not Fausto Carmona. The name Fausto Carmona belongs to someone else, and though the history of Cleveland Indians starting pitcher “Fausto Carmona” belongs to Roberto Hernandez, the two pitchers (the one pitcher) are not the same.

What I’m saying is: Roberto Hernandez is striking out batters.

He has a 22.5% K-rate right now. His previous career high was 17.1%, but that was mostly as a rookie reliever. As a starter, his highest K-rate was 15.6%. In fact, if we dig even deeper, we find his 22.5% K-rate is the highest strikeout rate he’s ever posted over a four game period:

His recent success — underscored and even underappreciated in his 3.75 FIP and 3.60 SIERA — appears to be the product of deliberate changes. That suggests he could maintain a new level of success.

Monday night, Jesus Montero went where no man has gone before — at least in 2013 — with this mammoth home run to center field at Minute Maid Park. With the blast, Montero became the first player to homer to dead-center field at Minute Maid this season. Observe, all home runs at Minute Maid Park, with 2013 home runs in blue (Montero’s marked by a “+”):

The third team to play while I was in Lexington was the Greenville Drive. Last year would have been the season to see this team as Garin Cecchini, Blake Swihart, Keury De La Cruz, Matt Barnes, Henry Owens, and others lined the roster. This season’s team definitely doesn’t have the star power, and I wasn’t terribly impressed by the overall level of talent. I will say, however, that the weather was cold – the low 50s/high 40s – and windy, but the team did not impress over the two games I saw them.

The Marlins and the Twins are playing a doubleheader on Tuesday. In the first inning of the first game, Giancarlo Stanton faced Kevin Correia with a man on, and Correia threw a first-pitch fastball at 89 miles per hour down the heart. Stanton swung and grounded into a double play, and one of the Marlins’ broadcasters remarked that it was probably Stanton’s best swing in a week, since returning from injury. Stanton finished the first game 0-for-3, dropping his average to .176. He has the worst average in the Marlins’ lineup, and the Marlins’ lineup sucks.

Let’s now go back a few months. Several months, I guess, depending on where you draw the line between “few” and “several”. After the Marlins swung the big trade with the Blue Jays, Stanton tweeted that he was pissed off. Now, I’ve been pissed off at lots of things I love and am loyal to to this day. I do, after all, still watch the Mariners. But that was a tweet of particular interest, because it helped to fan the trade-rumor flames. Already, the Marlins were probably eventually going to have to trade Stanton. Then the Marlins made Stanton upset, and who wants a surly ballplayer?

When we, as fans, use anecdotal evidence in our quest for baseball truths, we often over-emphasize iconic moments. Our sample degrades into big moments we can remember. So we turn to data to give us an unbiased look at the facts. But when a hitter evaluates himself and his swing, he usually turns to his memory for help. And though that evidence is anecdotal as well, the sample is huge — that hitter spends most of his time thinking about hitting, and all of his time being himself.

So it’s no surprise that Chase Headley knows best why Chase Headley showed more power in 2012. And that the slugger has had a complicated history when it comes to using data.

Back in November, Jack Moore wrote about the return of the stolen base as a valuable offensive weapon. As offensive levels have decreased in MLB over the last few years, the value of taking an additional base has gone up, and the cost associated with giving up an out has gone down, so we’ve seen teams running more often now than they did back when runs were plentiful.

It’s a perfectly logical construct. As hitting is more frequent, running becomes less necessary. When hitting suffers, teams try to find runs other ways to score, and one of the primary ways a team can create additional runs is through efficient base stealing. Base stealing is essentially a substitute good for power, and so SB rates follow a fairly predictable pattern of rising and falling depending on the offensive environment.

Except, that predictable pattern has gone off the rails so far in 2013.
