Colorado Rockies: Five individual, advanced offensive stats that must be fixed in 2021

Raimel Tapia average exit velocity (85.3 MPH): Bottom 6 percent of the league

Raimel Tapia had his best season in the majors in 2020 as he hit .321 with an OBP of .369. If he can get on base at that .369 clip for a full season, his speed (and being able to read pitchers pick-off moves well) will be the big key.

However, at the plate, in 2020, there may be an even bigger key: hard contact. His launch angle is among the worst in baseball (1.8 percent with league average being 11.9 percent) but he will never be a power guy but his hard contact rate is something that will help him get on base more.

However, if he could even get in the 5-6 percent territory, he would be able to sustain his 2020 season for the whole 2021 season and raise the slugging percentage by a wide margin.

For this exercise, though, we chose exit velocity over launch angle and barrel percentage, which is tied in somewhat with exit velocity but barrel percentage is more power-based. For his exit velocity, his average was 85.3 MPH. With a league average of 88.3 MPH, you may not think that it is a huge difference but it is. Just that 3 MPH difference is the difference between the middle mark (50th percentile) and being among the lowest six percent of qualifying major league players.
