This is what happens after he throws 2 innings, or when he pitches on consecutive days. His ERA doubles and he his swing-and-miss rate tanks. His cutter was sitting at 89-90. Even scrubs like my buddy's son Andrew Knapp were teeing off on him.

Roberts did the Joe Torre routine on Jansen's arm 2 years ago with all of the 2 inning saves and crazy over-use and he's never been the same. He melted down in the WS, his HR/9 has gone way up since that season and now he's 31 with a lot of miles on the arm. One more example of the price you pay for Roberts mis-managing the bullpen.
