According to the Wall Street Journal, the Indians starting rotation is the quickest working group in MLB-
“The Indians have two of the fastest-working pitchers in baseball, with Derek Lowe (17.1 seconds between pitches) and Justin Masterson (17.2) rating behind only Phillies ace Roy Halladay in pace between pitches. In fact, the slowest member of the Indians rotation—Josh Tomlin (19.2)—is still two seconds faster than the league-average starting pitcher so far in 2012.”
Obviously it is still early, but pitchers tend to have the same pace, or relatively close all season. Lowe and Masterson have always been quick workers. Gomez only had a couple of innings to demonstrate his pace before an early exit sticking up for Choo the other day.
