Lourdes Gurriel Jr.’s 2019 season was characterized by a loss of confidence in his throwing ability, a demotion to Buffalo, a position change, 37 missed-games due to a quad injury, and season-ending surgery to remove his appendix.
Grading system
I constructed my own grading method. It is a combination of a standard grade system and the 2018 fWAR percentiles for position players; Table 1 shows the grading scheme. The highlights are as follows:
- The data set of fWARs reflects any position player with a minimum of 100 plate appearances and an fWAR that is not negative
- An fWAR that is approximately in the top-third will earn a B
- A grade of C is awarded to an fWAR that is roughly the median of the data set
- I arbitrarily decided that any fWAR that is in the 15th or lower percentile receives an F
The evidence
Table 2 contains some data that is relevant for an assessment of Gurriel Jr.
