Thursday’s Cubs vs. Pirates game ended in a 1-1 tie after five innings because of rain. It will not be made up. On Friday, it will be another bullpen day and right-hander Jake Buchanan will get the start. He’ll be starting his second game since he was promoted from Triple-A Iowa. In 22 starts at Iowa, Buchanan posted a 4.35 ERA, striking out 97 over 130 1/3 innings. It won’t be his first big league start; he made two with the Astros in 2014.
