It was decision time for Major League front offices today.

All 30 teams had until 6 p.m. ET to make decisions about their 40-man rosters. Some prospects earned a coveted spot, some did not and will thus be eligible to be picked up by another team in the Rule 5 Draft, which will take place at the Winter Meetings in Orlando on Wednesday, Dec. 8.

Players first signed at age 18 must be added to 40-man rosters within five seasons or they become eligible to be drafted by other organizations through the Rule 5 process. Players signed at 19 years or older have to be protected within four seasons. Clubs pay $100,000 to select a player in the Major League phase of the Rule 5 Draft. If that player doesn't stay on the 25-man roster for the full season, he must be offered back to his former team for $50,000.

• Intriguing names added to 40-man rosters | Toughest decisions

For this year, that means an international or high school Draft pick signed in 2017 -- assuming he was 18 or younger as of June 8 of that year -- had to be protected. A college player taken in the 2018 Draft is in the same position.

There are 14 players on MLB Pipeline's Top 100 Prospects list who needed to be protected or become exposed to the Rule 5 Draft.

+ Julio Rodriguez, OF, Mariners (No. 2)
+ Hunter Greene, RHP, Reds (No. 26)
+ Royce Lewis, SS, Twins (No. 35)
+ Ronny Mauricio, SS, Mets (No. 53)

Over the past six seasons, all 59 Top 100 prospects who were eligible got roster spots:

2020: 7
2019: 13
2018: 8
2017: 8
2016: 12
2015: 11

There were far more Minor League players eligible, of course, with over 2,100 players on the Rule 5 eligible list this year; 169 were on organizational Top 30 lists. Last year, there were 174 ranked on Top 30s and 149 in 2019. The percentage of Top 30 prospects protected over the past six years:

2020: 86 of 174 (49.4 percent)
2019: 87 of 149 (58.3 percent)
2018: 71 of 149 (47.6 percent)
