Recall that we can use the batter's OBP, the pitcher's OBP, and the league OBP to find an expected OBP for a given matchup using the odds ratio. Since gOBP is still a proportion, we can use it to perform the same analysis. To determine which is more accurate, we first group the batters and pitchers into bins with width five points (.005). We then find an expected OBP for all pitchers and batters in that bin, and compare this to the actual results of those matchups. As an example, consider the first pair in our database: David Aardsma and Bobby Abreu, who faced each other once in 2010.
OPS stands for on base plus slugging and is exactly what it sounds like. You take a player’s OBP and add it to their SLG to get OPS. This stat is often used to measure a player’s overall ability as a hitter, combining their skill at getting on base (OBP) with their aptitude to hit for power (SLG). Sometimes it will be included at the end of a typical slash line, so if you see a slash with four different numbers in it, then OPS is what the fourth one represents.
Mike Napoli hit a career-high 34 home runs in 2016 with the Cleveland Indians, the third-most home runs in this free agent class, just agreed to a one-year deal, $8.5 million deal with the Texas Rangers in early February. The first baseman was worth just 1.0 fWAR after factoring in his base running skill (minus-5.2 runs) and defensive play (18th in DRS).
These are important because they show you how often (on average) a player walks and strikes out. Unlike batting average, K% and BB% are given in a direct percentage format, so there’s no need to translate it. The application of these stats is pretty straightforward; a player with a high BB% and low K% would typically have a good batting eye, and a player with opposite-type numbers would typically have a poor batting eye.
The second number in a slash line represents on base percentage. This is calculated by dividing the total times a player gets on base (hits, walks, and hit-by-pitch) by a player’s total number of eligible at bats, essentially all trips to the plate minus events outside of the batters control, like reaching on error and hitting into a fielder’s choice). These “eligible at bats” are calculated by adding regular at bats with the total number of times walked, hit-by-pitch, and hit into a sacrifice fly. That gives you the following formula to calculate on-base percentage, or OBP for short.
Am I the only person who feels cheated? I feel cheated out of seeing actual skilled batsmen. I feel cheated in that the only records being broken are by guys who seem to have the advantage of steroids. I feel cheated that home run records seem to be broken more than wooden bats, but hitting for average seems to be lost in the translation of the "new MLB."
If you want to hit farther, hitting the ball straight-on may not be the best way of doing it. Successful players who tend to score home-runs generally try to focus on hitting at the lower two-thirds of the baseball. This gives the hit both height as well as distance. So the next time you are aiming at hitting far, try to focus on the lower two-thirds of the baseball. This is a tough nut to crack and may take some practicing before you are able to master it.
A major league pitcher can throw a baseball up to 95 miles per hour -- some can move it even faster. At this speed, it takes about four tenths of a second for the ball to travel the 60 feet, 6 inches from the pitcher's mound to home plate, where the batter, with muscles as tense as coiled springs, like a predatory animal about to pounce, waits for the precise moment to swing at the ball. Baseball is a game played at the edge of biological time, just within the limits of a human's ability to react.

Players who hit 40 or more home runs produced 3.4 fWAR on average, the lowest rate since 2008 (1.8) and the third-lowest average on record since expansion, slightly behind the 1984 campaign (2.8 average fWAR from a batter with at least 40 home runs). Compare that with the average fWAR from batters with between 20 and 29 home runs (3.1 in 2016) and it is easy to see where the value lies.
Runs batted in (RBI): It's one of the most familiar and comfortable offensive stats around, and it's still got plenty of advocates. It's one of my least favorites, not only because of its native weaknesses but also because of its outsized importance when it comes to awards, bar-stool debates and the like. The primary problem with RBI is that it's highly, highly team-dependent. After all, it's hard to drive in many runs unless runners are getting on base in front of you, and that's not something you can control. Additionally, it's highly dependent upon your spot in the lineup. Take the exact same two hitters, put one in the leadoff spot and one at clean-up and you're going to get vastly different RBI totals. Like any traditional counting stat it's useful at the margins (e.g., it's hard to drive in 130 runs and somehow suck, but it's entirely possible to plate 100 runs and not be a useful player). Mostly, if you feel compelled to pay attention to RBI, don't do so without also paying attention to RBI percentage, or the percentage of runners than a batter plated. You can't consider RBI without also considering opportunities for RBI. - Perry

Overall, BABIP is a stat that is largely out of the batters control, which makes sense because as a hitter, once you hit the ball onto the field, you can’t affect what happens next. The league average BABIP is usually right around .300, meaning balls in play typically land for a hit about 30% of the time. So in theory, if a player has a BABIP of .350, you might say he had a “lucky” season, and you could expect him to regress the following season, right? On the surface it makes sense, but the whole point of this article is to look beyond just the surface stats, and that is exactly what we will do.
I am in a 14 team league with average and OPS, wish it was OPS and OBP. I had Dozier in that league, the year before I had Altuve and Dozier. I went after SanDiego’s Cabrera what a mistake. Hope to have Altuve and Dozier this year but for value Altuve looks to be a early 2nd round pick, that is to high for me, I would rather get a guy with power and RBI’s in the first two rounds.
FB% – This stands for fly ball percentage, which is the percentage of balls a player hits that end up as fly balls. Flies are the type of batted ball that are least likely to end up as a hit, and the league average is just .212 for a 21% success rate. Also, because a lot of fly balls end up as home runs, the league average BABIP for flies is even lower at .126, which tells us that fly balls that stay in the field end up as hits just 13% of the time. It’s no secret that players who hit lots of flies will suffer in the BABIP department, and a quick comparison of players with an above-league average FB% (.297 BABIP) to their counterparts (.318 BABIP) will really drive home that argument.
Runs Batted In: "The guys that knock em in," as Leyland calls them, do make the big bucks in the baseball market. But RBI are, to a great extent, a function of opportunities. You can’t drive in runs, other than solo home runs, unless there are runners on base to drive in. A typical lineup should be arranged so that the big RBI guys follow guys who frequently get "on base, on base, on base." Leyland happened to be talking about Jhonny Peralta, his 80 RBI, and his value to the team when he launched into his philosophical discussion of on-base percentage. What he didn’t mention was that Peralta led the league in at bats with runners in scoring position the previous two seasons. It should be understood that players who get hits tend to also get hits with runners on base, or in scoring position, at about the same rate, averaged over time.
OPS stands for on base plus slugging and is exactly what it sounds like. You take a player’s OBP and add it to their SLG to get OPS. This stat is often used to measure a player’s overall ability as a hitter, combining their skill at getting on base (OBP) with their aptitude to hit for power (SLG). Sometimes it will be included at the end of a typical slash line, so if you see a slash with four different numbers in it, then OPS is what the fourth one represents.
There is a very important Biomechanical Principle that pertains to the initiation of the baseball swing. The principle states: "A ballistic motion, once initiated, produces trajectories that can only be changed at its margins." This means, the forces applied to the bat during initiation produce trajectories that will set the tone for the entire swing. If the swing is not initiated correctly - little can be done to compensate for it.
Here's how to practice the proper weight shift going back. Set up with your driver, but take a narrow stance, about 12 inches wide. Then make a slow-motion swing, stepping out with your right foot as you start the club away (above). This side step will get your weight shifting to the right. With your weight in your right instep, you're in position to drive your body toward the target as you swing down. That's how you hit the ball with power.
In Part 1, we'll take a look at the method to the madness of on base percentage (OBP) and slugging percentage (SLG) and see if we can give them their due respect on the scale of importance. In part 2, we'll explore why wOBA is a better stat to use than OPS and produce a scale so we can easily see what wOBA is above or below average and how the Tigers' players fit in.

"It's all about having a quality at bat," said Garrido, who has won five national titles. "You can't just go up there and start swinging and expect to get hit after hit. You have to be able to separate the pitches you can hit and the pitches you can't hit. And when you find that pitch let the ball location help you decide where you want to hit it. If you can do that you are on your way."
