Keller (4-10) did not factor into the decision Thursday, pitching six scoreless innings while giving up six hits with eight strikeouts and zero walks in a loss to the Cubs.
Keller turned in arguably his best start of the season, tying his season high in strikeouts. The right-hander was in line for win No. 5 on the season when he exited, but the Bucs bullpen immediately surrendered the lead. The 25-year-old will take a 6.23 ERA into his next start, likely coming next week against Detroit.
