They are tied with the Milwaukee Brewers for the worst record in MLB, but the Phils would get the pick because they had a worse 2014 record than the Brewers.
MLB Standings
The gap in run differential between the Phils and the second worst team is now up to 13: the Phillies are at -60, vs. the Rockies' -47.
The pythagorean projection based on that run differential puts them on pace for a 46-116 record.
The Pirates are similar to the team that just left town -- they've gotten very good pitching (though not quite as good as the Mets), but their hitting has been even worse than New York's.
