PHOENIX -- Cubs manager Mike Quade was asked on Thursday night about the tweeting controversy surrounding Ozzie Guillen, his White Sox counterpart.
Major League Baseball is reviewing Guillen for sending out several tweets after he was ejected during the first inning of a game at New York against the Yankees on Wednesday night.
MLB policy is that all social media messages by baseball personnel should cease within 30 minutes from the start of a game. Guillen tweeted his displeasure with the ejection several times while the game was still in progress.
Quade said that will never be an issue for him.
"I will never get in trouble Twittering," Quade said prior to the opener of a four-game series for the Cubs against D-backs at Chase Field.
When told that the term was "tweeting," Quade added: "See? I can't even say it. I will not get in trouble because I will never do it. I don't have the time, energy or the know-how."
Quade, 54, admitted he's well within the generation of people who should know how to do such things, but it doesn't interest him.
"I have a BlackBerry. That's the extent of it," he said.
Dempster's struggles follow him to Arizona
PHOENIX -- Cubs manager Mike Quade said before Thursday's series opener in Arizona that he hoped right-hander Ryan Dempster had all his bad starts for the season behind him.
But the roughest was yet to come.
Dempster allowed seven runs on four walks and four hits, including Stephen Drew's first career grand slam, and was chased after just one-third of an inning. It was the shortest outing of the 14-year veteran's career.
Justin Berg replaced Dempster and finished the inning without any further damage. The Cubs ended up losing, 11-2.
"No one's trying to figure it out harder than him," Quade said about Dempster before the game. "He's just not making the quality pitches he makes when he's succeeding. His velocity's OK. There are no certain signs to look at. I think he's fine. I just think his slider is his bread and butter. He hasn't had the quality slider he's accustomed to.
"When you hang a slider it sometimes gets you in a lot of trouble, even more so than a fastball. It could be a double-edged sword. It's great if you're throwing it the way you can. But it can be miserable if you're not."
Dempster went into the game at 1-2 with a pair of no-decisions and 7.63 ERA. In his five previous starts, he hasn't allowed fewer than four earned runs in any game. His last time out at home against the Dodgers this past Saturday, Dempster allowed seven earned runs on nine hits in 5 2/3 innings. The Cubs came back to win the game, 10-8.
"I don't know whether [his problems] are mechanical or whatever it is," Quade said. "That's my view of it anyway."
Dempster is coming off a 15-12 season in 2010, when he had a 3.85 ERA in 34 starts. His best season for the Cubs was 17-6 with a 2.96 ERA in 2008.
Cubs tab Coleman to start Sunday's finale
PHOENIX -- Cubs right-hander Casey Coleman is slated to start Sunday's finale of a four-game series against the D-backs at Chase Field.
He could have been pressed into service Thursday night after starter Ryan Dempster lasted just one-third of an inning in the Cubs' 11-2 loss. But Justin Berg pitched 3 2/3 innings and Jeff Samardzija, John Grabow, Marcos Mateo and Carlos Marmol each added an inning.
"I was glad the bullpen did such a good job," Cubs manager Mike Quade said. "Bergie did such a good job protecting our 'pen. So we're in decent shape for [Saturday], which was huge, and he also protected our starter for Sunday."
Had Coleman been used Thursday, his start likely would have been pushed back to Monday in Los Angeles, leaving the Cubs in need of a spot starter for Sunday.
"The bullpen did a nice job because I did not want to go to Casey and put us into a little trick bag on Sunday and Monday," Quade said.
Quade will have to find a spot starter to face the Dodgers on Monday, and he said he hasn't determined who that's going to be yet.
"I can tell you what I'm not going to: I'm not going to all hands on deck," Quade said. "That I'm not going to do."
What Quade didn't want to see was a continuation of the monthlong problems experienced by Dempster, who was tagged for seven runs on four hits and four walks on Thursday. Dempster hasn't pitched any farther than seven innings in his first six starts.
Coleman was supposed to start at Wrigley on Wednesday against the Rockies. But when the game was rained out, Quade elected to leave his top three starters -- Dempster, Carlos Zambrano and Matt Garza -- in place to pitch the first three games of the series. Coleman was thus bumped back to start on Sunday.
"We wanted to keep those guys on their normal rest," Quade said. "We didn't want to back them up. Sometimes when you're the young guy on the staff, this happens."
