Renteria making sure to keep Starlin engaged
By Carrie Muskat / MLB.com
CHICAGO -- Cubs manager Rick Renteria says he and his staff are very talkative, and one of the players they are constantly engaging with is shortstop Starlin Castro.
"It's just part of how we do things," Renteria said Monday. "We're kind of vocal. I think that's our nature. I remember playing for managers who were always talking to us in the infield. I don't think it's abnormal."
Part of the rationale is to keep Castro focused on the game and avoid any mental lapses. Renteria said Castro, 24, who was promoted from Double-A in 2010, is still developing.
"He got here when he was 20 [years old] and we assume he knows exactly everything he's doing, and I think he's still learning," Renteria said. "I think we make a mistake that any player in the big leagues is not still learning."
Castro entered Monday's game batting .395 at home, and has hit safely in all nine home games.
Tickets on sale for 'Cook-Off for Cancer' fundraiser
CHICAGO -- Tickets are now on sale for Anthony Rizzo's second "Cook-Off for Cancer" fundraiser to be held May 16, 6-10 p.m. CT, at Revel Downtown, 440 W. Randolph, in Chicago.
Last year's event raised more than $150,000 to help and support families with children fighting cancer.
Rizzo and the Cubs players and coaching staff will be serving food and competing for tips, with proceeds going to benefit pediatric cancer research, care and support.
Participating chefs include Lee Ann Whippen of Chicago q, Mario Hernandez of Del Frisco's, Giuseppe Tentori of GT Fish and Oyster, Joseph Farina of Joe's Fish, David Burns of Levy Restaurants, Molly Johnson of Limelight Catering, Tony Priolo of Piccolo Sogno, Cosmo Goss of Publican, Doug Psaltis of RPM Italian, Doug Tomek of Uncle Dougies, and Joseph Heppe of Untitled.
Rizzo was diagnosed with Hodgkin's lymphoma at age 18, and endured six months of chemotherapy. On Sept. 2, 2008, he was told he was in remission.
"Fighting cancer is a battle for the entire family," Rizzo said. "The child endures the cancer treatments, but it's his or her family struggling to pay all the bills, shuttling back and forth to appointments, and hurting for their child."
Tickets for the event are $200 per person with limited number of tables available for $1,200. For tickets and information, visit www.cubs.com/cook.
Arrieta closing in on return to Cubs' rotation
CHICAGO -- As of now, Carlos Villanueva stays in the Cubs' rotation, but Jake Arrieta is getting close to returning to the big league team.
Arrieta, who was slowed this spring with tightness in his right shoulder, made his fourth Minor League rehab start on Monday, pitching for Class A Daytona, and gave up five runs -- three earned -- on five hits, including three homers, over 5 2/3 innings. Arrieta struck out seven, including the last two batters he faced in the sixth. He has made three starts for Double-A Tennessee, but the Cubs wanted Arrieta pitching in warm weather and to go about 100 pitches on Monday.
Will a start at Class A be enough to prep Arrieta for the big leagues?
"I think the intensity level that everybody has when they're down on rehabs, everybody's different," Cubs manager Rick Renteria said. "Some guys don't think about it too much and just focus on what they're doing. Some guys see it as kind of being lax because it's a different arena.
"In his case, he's a guy who goes out there and knows he has to command and stay clean in his delivery and hit his spots," Renteria said. "It might be a little different for pitchers than position players."
Renteria said they won't know if Arrieta will need another rehab start after Monday until they see how he responds from the outing.
Villanueva is 1-2 with a 10.66 ERA in three starts, and will go to the bullpen when Arrieta returns.
• Fans who can't attend Wednesday's 100th anniversary party at Wrigley Field will be able to watch the pregame festivities on WGN-TV, which will cover it live.
The show will start at 12:30 p.m. CT on WGN-TV Chicago and nationally on WGN America. The Cubs play the Diamondbacks at 1:20 p.m. CT, one century after the Chicago Federals played their first game at then-Weeghman Park against the Kansas City Packers.
After the starting lineups are announced, members of the Northwestern University marching band will take the field, which was customary for Opening Day and other special events during the ballpark's first two decades.
Major League Baseball Commissioner Bud Selig will attend as well as past and present team owners. The Chicago Bears, who played 50 seasons at Wrigley Field from 1921-70, also will be honored.
Before the game, Cubs alum will take the field, including Ernie Banks, Glenn Beckert, Andre Dawson, Ryan Dempster, Bobby Dernier, Randy Hundley, Fergie Jenkins, Gary Matthews, Milt Pappas, Lee Smith, Billy Williams, Kerry Wood, and Sam and Spencer Brown (grandchildren of Ron Santo).
• Wednesday's game will be the eighth time the Cubs will wear throwback uniforms in a regular-season game, and first of 10 such instances this year. Chicago is 6-1 so far in the retro uniforms. On Wednesday, the Cubs will wear versions of the Chicago Federals' uniforms.
