Keller (11-10) took the loss Saturday, giving up four runs (three earned) on four hits and a walk over six innings as the Pirates fell 5-1 to the Royals. He struck out six.

While only one of the runs against Keller was unearned, the Pirates' defense made numerous miscues beyond the two official errors charged to Nick Gonzales and Jared Triolo on the afternoon. Keller still came away with his 15th quality start of the season, and over his last five outings he's posted a 3.49 ERA, 1.24 WHIP and dazzling 34:3 K:BB in 28.1 innings. He'll look to get back in the win column in his next start, which is scheduled to come on the road next week in St. Louis.
