Jackson working to get back on winning track
By Carrie Muskat / MLB.com
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.
Cubs bolster bullpen by recalling Rusin
CHICAGO -- The Cubs added a fresh arm to the bullpen on Wednesday, recalling lefty Chris Rusin from Triple-A Iowa. Blake Parker was optioned to Iowa to make room on the 25-man roster.
The Cubs were reportedly working on a deal involving infielder Emilio Bonifacio, which would have allowed them to keep Parker on the 25-man roster.
Rusin, 27, has spent the majority of the season with Iowa, going 7-11 with a 3.76 ERA in 19 starts, including a no-hitter on May 7 in New Orleans.
In two relief appearances with the Cubs this season, Rusin has given up six earned runs over 8 2/3 innings.
Parker, 29, has appeared in seven games, spanning four stints with the Cubs this season. He has spent the majority of the year with Iowa, posting a 1.29 ERA with a Pacific Coast League-leading 21 saves in 28 games.
Parker was one of eight pitchers, including backup catcher John Baker, to pitch on Tuesday in the Cubs' 16-inning game, a 4-3 win over the Rockies.
