Can't believe the Marlin collapse last night, but on further review it's even more difficult to blame Guillen there for summoning Heath Bell in the 9th.
Bell, for all his troubles early in the season, had gone 10 appearances in a row, covering nearly 10 full innings, without giving up a single run. Bell was 7 for 7 in save opportunities during that stretch spanning all the way back to the last week in May.
I'm sure the 4 run lead seemed a safe call and a sure thing for the guy. He just had a terrible outing.
