This question was raised in the comments section, if maybe the Phillies have an incentive to leave Brown in the minors for x amount of time based on salary considerations. The Phillies have shown a willingness to bring guys up in the past when they are ready and not worry about the clock. Brown is on the 40 man roster, so that isn’t a consideration. Let’s look at the facts. For determining Super 2 status, arbitration, and free agency, MLB functions under the “Service Time” metric, and it goes in years.

1 year of MLB service time = 172 days on the 25 man roster, or on the MLB DL during the season.
1 MLB season generally consists of 182 days.

Players with 2 years or less of service time are eligible to have their contract renewed for the MLB minimum (or an amount the team chooses) unless they signed a contract previously which guarantees them a different dollar amount. Players with more than 2 years of service, but less than 3 years of service who have at least 2 years + 86 days of service time are put into a group. Of that group, the top 17% are deemed “Super 2” players and are eligible for salary arbitration. Over the last few seasons, the cutoff for “Super Two status” has been right around 2 years + 140 days of service time. After you have 6 years of service time or more, you are a free agent. So, let’s apply this to Brown.

Last year, Brown accumulated 68 days of service time.
As far as I know, when he was placed on the DL in spring training, he did not begin to accrue service time, as that only counts if the player is injured during a regular season game, when service time is assigned. Thus, he currently has 0 days of service time in 2011. Lets assume he comes up on June 1 of this year and then never goes back to the minors.

2010 = 68 days of service.
2011 = 120 days of service. (1.016 years total)
2012 = 182 days of service (2.016 years total)
2013 = 182 days of service (3.016 years total)
2014 = 182 days of service (4.016 years total)
2015 = 182 days of service (5.016 years total)
2016 = 182 days of service (6.016 years total)

So Brown will be a free agent after 2016, if he doesn’t sign a long term deal first. The Phillies would essentially have to trim 17 days off of his service time in 2011 to prevent this from happening.

120 days (figured above, as June 1 being the target) -17 days is June 18th.

Update —> Thanks for pointing this out in the comments about the 1 year of service. I originally had this as my estimate, then thought I was wrong and changed. I’ve now fixed it. Much better.
