It's pretty clear that Don Mattingly doesn't care for Alex Guerrero. Guerrero only has 23 at-bats in the last ten games and continues to ride the pine.
Fantasy Impact
Guerrero not getting playing time is more of an indictment on Mattingly rather than Guererro's performance. Apparently Mattingly doesn't care about advanced stats as Guererro carries a .394 wOBA, 155 wRC+ and a .336 ISO. If you're not playing in an NL only league or a 15+ team mixed league you can feel free to drop the talented Cuban.
