Coaches hopeful to have found Jansen's flaw

SAN DIEGO -- The Dodgers are hopeful that they've spotted a mechanical flaw in reliever Kenley Jansen that has led to the four home runs he has allowed in the last 10 innings.

Bullpen coach Ken Howell said pitching coach Rick Honeycutt determined through video comparison with last year that Jansen has been pushing off with a stiff right leg and not utilizing the lower half of his body, resulting in decreased velocity and movement.

And resulting in home runs. He served up a 445-footer to Cameron Maybin on Opening Day, after allowing three in only nine Spring Training innings. In the regular season last year, Jansen allowed only three home runs in 53 2/3 innings.
