Service time of 2020 players who were optioned for less than 20 days

 2020 MLB season was shortened due to COVID-19 pandemic, so the exceptional method was applied for calculating player's service time.

Like usual years, service time for 2020 consisted of days on active roster and some inactive list (like injury list). But, it was calculated with numbers pro-rated (multiplied) based upon the ratio of 67 days to 186 days (Each day as approximately 2.78 days of MLB Service Time). 

However, there are some points to keep in mind when calculating the service time of players who were optioned for less than 20 days in 2020.Such players were credited with service time through their option days, but their bonus days were NOT PRO-RATED.

Here is the table of Service time of 2020 players who were optioned for less than 20 days.

Club:     player's reserved club as of 3/1/2021

Real ST:     service time counted by real days except days on option

PRST:     pro-rated service time except days on option

DOP            days on option

Bonus ST:   days on option except duplication

            (If a player is optioned prior to the game of the day, that day is counted as both service time and day on option)

2020 ST:     service time for 2020 (PRST+Bonus ST)

career ST:    career service time
