For some reason, swinging at the first pitch is something of a divisive act. Like just about everything, it is a largely a product of results. Player swings at first pitch and makes out? Bad idea. Player swings at first pitch and reaches? Aggression is good!

The numbers suggest that swinging at the first pitch is often good for business, even if our mind tricks us into thinking otherwise.

Quite obviously, swinging at the first pitch is contingent on the first offering of the at bat being hittable. Swinging away at just anything a pitcher throws up there is not good for anyone, in any count. But the hitters of the world thrive when they jump on the first pitch, as evidenced below.

The numbers suggest the first pitch is a great time to rake: hitters slug the first pitch at a high rate, much higher than other even counts. Swinging at the first pitch is also wise at it represents a high likelihood of seeing a fastball. Since the beginning of the 2011 season, 57% of the first pitches thrown to qualified hitters were fastballs. 53% of those pitches were in the zone. Fastball in the zone? Pull the trigger, friends.

While the league-wide numbers suggest swinging at the first pitch (if it is a strike) is good on the whole, there are plenty of players who individually excel at hitting first pitches. Matt Kemp has 12 first pitch home runs since the beginning of last year, though Aramis Ramirez leads with 15 first pitch homers. Of Kemp’s 12 long balls, 10 came on fastballs.

According to ESPN Stats & Info, Aramis Ramirez also leads with 64 “well hit balls” on first pitches, with Robinson Cano, Josh Hamilton, Miguel Cabrera and Michael Young (!) rounding out the top five. As a whole, qualified hitters have a .297 Well Hit Average, comparing well to 3-1 counts (.355 Well Hit Average) and 3-0. where hitters have a .424 WHA, though fewer hitter swing 3-0 as a rule. Big leaguers swing at 3-0 pitches just 7.5% of the time, compared to 54.8% of 3-1 pitches. The league swings at the first pitch 25.9% of the time.

The other major advantage of being aggressive with the first pitch seems obvious, when the numbers listed above are considered. Falling behind in the count is deadly. Hitters on the first pitch own a .848 OPS but falls to .603 after falling behind 0-1.

Hitting 1-0 is as beneficial to a hitter’s numbers as falling behind is detrimental. It certainly seems like something worth considering, contrary to what we all told each other in little league. Really, it all comes back to fastballs. More fastballs means more line drives, it would seem.

It is a delicate balance to strike, quite obviously, between aggression and hacking. How a professional hitter can maintain that balance…well that is what makes these guys so good and, eventually, rich. Good hitters post great numbers in just about every count mostly because they’re good hitters, the count is just the framing device. A good approach needs to be applied at all times: see a pitch in your zone and drive it. Simple, right? I’ll just sit here by the phone, waiting for the roving hitting instructor job offers to roll in.
