How Mitch Keller Showed Maturation Against Potent Astros’ Lineup (+)

PITTSBURGH — Ever since Mitch Keller rejoined the Pittsburgh Pirates’ rotation after a brief stint in the bullpen last season, he has looked like a brand-new pitcher.

Since May 31 of last year, Keller entered Tuesday’s game against the Houston Astros with the sixth-lowest ERA in the National League with an impressive 3.27 mark.

The progress he’s shown would be put to the test against the reigning World Series champion Astros and their impressive lineup.

Keller may have allowed a pair of early home runs, but he was able to keep his composure. He gave the Pirates six quality innings on the mound as kept his team in position to pull out a victory.
