Knack has given up 1 run through 5 innings and he had only thrown 64 pitches. Knack has an ERA of 2.8. So Dave pulls Knack after 5 and brings in Grove (also a RHP) who has an ERA of 7. Knack could have easily gone 6 or 7 innings, but Dave's going to force his overused bullpen to throw 4 more innings tonight. And Grove loads the bases before being pulled. Freaking Roberts gives away 5-10 games a year with his stupid pitching moves.
