CHICAGO -- The process of getting Edwin Jackson back on track began Wednesday when Cubs bullpen coach Lester Strode met with the right-hander in right field prior to the game to talk about the night before.
Jackson did not get a decision against the Rockies on Tuesday, lasting four innings. He had to be pulled because of his pitch count, which reached 105. He served up three runs in the first inning, and now has given up 19 earned runs in the first inning in his 22 starts for a 7.77 ERA.
In his last six starts, Jackson is 0-3 with a 7.50 ERA, and opponents were batting .328.
"We have to try to put our finger on what it is, whatever the stumbling block is," manager Rick Renteria said Wednesday. "I'm sure [pitching coach Chris Bosio] and [Jackson] and Lester will get to the crux of it. He's going to get the ball again and give us another shot."
Jackson's next start is scheduled for Sunday against the Dodgers.
