The curious case of Kyle Tucker’s quiet free agency
The Major League Baseball offseason is not known for moving at the quickest pace. There is usually some activity around the Winter Meetings in mid-December, but top free agents are regularly still signing well into Spring Training in March.
My producer, David Korn, wrote about the lack of rumors and reports surrounding Kyle Tucker’s free agency.
STAT OF THE WEEK - Expected Slugging Percentage (xSLG)
Expected Slugging Percentage (xSLG) is formulated using exit velocity, launch angle and, on certain types of batted balls, Sprint Speed.
In the same way that each batted ball is assigned an expected batting average, every batted ball is given a single, double, triple and home run probability based on the results of comparable batted balls since Statcast was implemented Major League wide in 2015. For the majority of batted balls, this is achieved using only exit velocity and launch angle. As of 2019, “topped” or “weakly hit” balls also incorporate a batter’s seasonal Sprint Speed.
All hit types are valued in the same fashion for Expected Slugging Percentage as they are in the formula for standard slugging percentage, with doubles being worth twice as much, triples being worth three times as much and homers being worth four times as much as singles. The single, double, triple and home run probabilities for an individual batted ball are plugged into the formula for slugging percentage -- (1B + 2Bx2 + 3Bx3 + HRx4)/AB) -- to get a player’s Expected Slugging Percentage on said batted ball.
