5:43pm: The Yokohama BayStars signed Leach, according to Patrick Newman of NPB Tracker.
5:07pm: The Dodgers designated Brent Leach for assignment, according to Dylan Hernandez of the LA Times (on Twitter). The lefty appeared in 38 games for the Dodgers in 2009, but hasn't surfaced in the majors since.
Like Scott Nestor, whom the Dodgers signed today, Leach has struggled with command and posted high strikeout totals as a professional. Leach, who has started occasionally in the minors, has posted 9.3 K/9 and 4.9 BB/9 over the course of his six-year minor league career. Last year he posted a 5.25 ERA with 7.7 K/9 and 4.6 BB/9 in 104 2/3 innings for the Dodgers' Double-A and Triple-A affiliates. Now 28, Leach has been in the Dodgers organization since they selected him in the 6th round of the 2005 draft.
