From Fraley...

+ For the eighth time this season, Rangers' manager Ron Washington used the bullpen for five-plus innings. That is the most five-plus-innings games for a bullpen in the American League. Kansas City, last in the AL Central, has done it seven times. The Los Angeles Angels, whose manager MIke Scioscia fiercely protects his bullpen, and the New York Yankees have done it only once.

The Rangers lead the American League in bullpen innings with 120, which translates into a 540-innings pace for a full season. Bullpens get into the burned-out zone once they go past about 475 innings.

I am sure some of those games mentioned by Fraley were of the extra innings variety. But, his point stands:  the bullpen is overworked. Harden, Feldman and to some degree Ron's small ball desires are taxing the pen. Harrrison got alot of grief around LSB but at least he was near lg avg in IP/GS.
