Highest Leading ERA this Year?

I was surprised to find that 2006 may set a new record for highest ERA to lead the majors! Currently, Josh Johnson of Fla. Marlins is the lowest qualifier (1+ innings per game played by team), and his ERA is a not-so-impressive 2.84 (Liriano of Minn. was listed as leader for awhile, and currently stands at 2.19, but with only 119 IP and on the DL right now, it's not likely he'll pitch enough innings to qualify.) The highest ERA to ever lead the majors for the year was Lefty Grove's 2.81 in 1929, baseball's first "juiced ball" era. THe highest since then was Saul Rogorin's (who's?) 2.78 in 1951, and the highest ERA to lead the majors in recent years is Jimmy Key's 2.76 in 1987.
