Chicago Cubs first baseman Busch has taken another step forward in his development this year, which has included raising his on-base percentage by nearly 40 points.

Starting pitcher Jameson Taillon threw 47 pitches during a bullpen session Friday at Wrigley Field, per the Cubs. He was placed on the 15-day injured list on July 4 with a right calf strain. Prior to his injury, Taillon had a 4.44 ERA and a 1.11 WHIP across 95.1 innings, including 10 quality starts.
