Two quick site announcements this afternoon:

• We've updated the draft data to include results from earlier this month.
• Short-season minor leagues like the Appalachian, Arizona, Gulf Coast, and Pioneer Leagues (in addition to the Dominican & Venezuelan summer leagues) will now be updated daily.

Two notes:

- We have added minor-league player newsfeeds to the site, so now the names of any active minor-leaguers will be linked when you use the Automatic Player Linker Tool. Click here to read more about the linker program, and to learn how to submit your content to the B-R newsfeeds.

- Also, please welcome the following sites to the linker program:

Thanks for your feedback!

After months of technical difficulties, we're happy to say that the Oracle of Baseball is once more operational.

For those who don't remember it, the Oracle is a tool that allows you to find connections between any two major league players via teammates. (As an example, here is the shortest possible chain of teammates between Joe Tinker and Starlin Castro.)

For more information about the Oracle, click here. Thanks for your patience as we worked to get the Oracle up and running again.

I'm pleased to announce that Mike Kania has joined Sports Reference as a web developer. Mike previously worked as a developer for SixApart and AOL and also designed the very valuable reference site HasTheLargeHadronColliderDestroyedTheWorldYet.com. He dramatically increases the number of Cleveland fans on staff (bringing us to one) and works in our Philadelphia office. Mike will be focusing on football initially. He's been on the job a couple of weeks and is already close to rolling out a couple of new features on the football site.

Quick announcement about the Minors section of the site: we ran the most recent SABR update yesterday, so stats from the Dominican Summer League and Venezuelan Summer League are now updating daily.

2011 New York Yankees Batting, Pitching, & Fielding Statistics - Baseball-Reference.com.

Last year in August, there was a bit of a debacle when I started incorporating 2010 season stats into the park factors. Yankee Stadium III had been a much better hitters park and SafeCo a better hitter's park and adding in the 2010 season stats swung the AL pitcher WAR race (temporarily) in Sabathia's favor.

To avoid a similar problem this year and in future years I am going to begin updating the park factors around Memorial Day.

UPDATE: The Win Probability Added calculations for 2011 will also be updated daily to reflect the 2011 park factors and run scoring environment.

The Park Factors on B-R are 3-year factors when appropriate, so 2000's park factor relies equally on 1999, 2000 and 2001.

So now for 2011 since it is underway, we start with the PERCentage of the season played and

PF_2011_3yr = (PERC*PF_2011 + PF_2010 + (1-PERC)*PF_2009)/2

PF_2010_3yr = (PERC*PF_2011 + PF_2010 + PF_2009)/(2+PERC)

This should prevent violent swings in the park factors and at the end of the season we will end up with PF we were going to have throughout the offseason.

2011 pages will of course be updated daily. 2010 pages will be updated less often. To see what goes into each team's park factor you can look at the various one-year park factors listed on their team/year pages.

A quick note to let everybody know that we now list WHIP and ERA+ on the Cy Young Award voting tables:

2010 NL Cy Young Voting

1969 AL Cy Young Voting

Special thanks to B-R user Brendan for the suggestion!
