Hiram Burgos has already represented Puerto Rico in this year's World Baseball Classic, so forgive the 25-year-old if he doesn't feel too nervous as he readies for his Major League debut.
Burgos, Milwaukee's 2012 Minor League pitcher of the year and the club's No. 13 prospect according to MLB.com, takes the ball Saturday night in Milwaukee against the Cubs.
Edwin Jackson, Chicago's top free-agent acquisition this offseason, opposes Burgos and is still searching for his first win as a Cub.
Burgos had quite a year in the Brewers organization last season, combining to go 10-4 with a 1.95 ERA at three different levels. That effort earned him a spot on Team Puerto Rico in the World Baseball Classic, where he allowed one run and struck out 12 in three relief appearances spanning 13 innings.
That experience, Burgos believes, will help settle any butterflies he might have Saturday.
"That was the biggest stage I was on before," Burgos said. "I always say, 'It's the same baseball no matter where you are, whether you're here or the Minor Leagues.' The crowd is the only thing that changes."
His skipper agrees.
"I think going through the WBC probably helped him a lot with what's going to happen [Saturday]," manager Ron Roenicke said. "Those were some big games that he was involved in, and he pitched really well. I think he's going to be fine."
The Cubs and Jackson are hoping the Chicago righty pitches well, too, as he has struggled with his new squad. Jackson has a 6.06 ERA in three starts, one of which came against the Brewers in Chicago's home opener on April 8.
Jackson has finished six innings just once this season, and while he's allowing runs at a high rate, he has thus far avoided the long ball. Jackson hasn't surrendered a home run after giving up 23 last season with the Nationals.
Cubs: We're going streaking!
• Shortstop Starlin Castro went 1-for-4 on Friday to extend his hitting streak to 11 games. It's Castro's eighth hitting streak of 10-or-more games since 2011, tying him with Yankees second baseman Robinson Cano for the most such streaks in the Majors in that time.
• Left fielder Alfonso Soriano also has a five-game hitting streak in which he's batting .524.
• Soriano needs two doubles for 200 with the Cubs. He would become the 30th Cub to reach the mark.
• Dioner Navarro is three hits shy of 500 for his career.
Brewers: It starts with pitching
• Burgos follows a string of strong outings by Brewers starters, who have seven quality starts in the last nine games after posting only one in the first six.
The bullpen also is getting in the mix, going 3-0 with a 1.33 ERA and three saves in that stretch.
• Left fielder Ryan Braun needs two homers to tie Gordon Thomas (208) for fourth place on the club's all-time list.
• Milwaukee is 16-2 in its last 18 games against Cubs at Miller Park, including a six-game home winning streak.
• Jackson is 3-3 with a 3.57 ERA in eight starts starts against the Brewers. Braun (.318, 7-for-22) and Jonathan Lucroy (.357, 5-for-14) have hit him well.
• The Cubs are batting .144 with runners in scoring position. Milwaukee, meanwhile, has been hot in such situations, hitting .478 in their last four games.
