I just waived him to take a flier on Walker. I really need a second closer and I doubt Takatsu will be it...
Since April 25th:
Takatsu 4 g, 2 sv, 0 bs, 2 losses, 3 1/3 IP, 5.4 ERA, 6 K, 1.5 WHIP
Hermanson 8 g, 5 sv, 0 bs, 0 losses, 9 2/3 IP, 0 ERA, 4 K, .72 WHIP
Takatsu's getting hit and currently Hermanson isn't. Guillen has expressed concern with teams that see him more than a few times, which doesn't bode well for his fantasy value. Tak does strike out a few more, but that's about the only positive right now.
