Dodgers closer Kenley Jansen, who has struggled badly since returning from the disabled list after a second diagnosis of an irregular heartbeat, says he's had enough of his heart medicine and what it has done to his on-field performance. Since being activated and while on medication, which he says he discontinued on Sunday, Jansen went 0-2 with a blown save while allowing seven hits, five runs (all earned) and four home runs in three outings, one inning each. Jansen compared the feeling he would get on the field to "sleepwalking," when instead he needs what he called "the good anxiety" to pitch his best.
