...Daisuke Miura felt tightness in his lower back on Tuesday and canceled his bullpen session. His scheduled start on the 5th was also postponed. Miura basically spent most of his time on Tuesday playing catch. He has not thrown a bullpen session since 2/23. Miura threw 1,770 pitches during Spring camp.
