Miami Marlins Starting Rotation, Round Six

Anointed the “staff ace” near the very start of Spring Training, José Ureña took some time to get going. Now after six turns, he ranks fourth out of the starting five, but he’s still really close to last place.

Initially, I was using the original GameScore metric to rate and rank the starters one against the other, but recently swapped over to Tom Tango’s Game Score Version 2.0. The newer model penalizes equally for hits and walks, equally for runs whether earned or unearned, and adds a significant penalty for giving up home runs. I used the last 10 starts, weighted so that more recent games count more than the ones that were played longer ago.
