PITTSBURGH -- Wandy Rodriguez was truly the ice man Wednesday night.
On an evening when the game temperature was 35 degrees and the wind was blowing out to center field at 17 mph, the Pittsburgh Pirates left-hander cooled the Chicago Cubs' bats as he combined with two relievers on a two-hit shutout in a 3-0 victory at PNC Park.
Rodriguez (1-0) allowed both two hits, singles by Alberto Gonzalez in the third and Alfonso Soriano in the seventh. Rodriguez also struck out six and walked one in his first start of the season.
Tony Watson retired all four batters he faced and Jason Grilli pitched a perfect ninth inning to convert his first save opportunity of the season as he takes over at closer for All-Star Joel Hanrahan, who was traded to Boston in the offseason.
Rodriguez was in control until the late innings, not allowing the Cubs to get a runner to third base until the seventh inning.
Down 2-0, the Cubs loaded the bases with one out. Rodriguez hit Anthony Rizzo with a pitch, gave up a single to Soriano then hit Welington Castillo.
Rodriguez struck out Brent Lillibridge with a 3-2 backdoor slider then yielded to left-hander Tony Watson, who escaped the jam by getting Gonzalez to hit an inning-ending fly out to center field.
The Pirates then added an insurance run in the bottom of the seventh when Clint Barmes hit a double down the left-field line that bounced into the stands and scored on Starling Marte's one-out single.
The Pirates opened the scoring with a two-run fourth inning off Edwin Jackson, who was making his Cubs' debut after signing a four-year, $52-million contract as a free agent in the offseason.
Garrett Jones led off with a single and scored on Andrew McCutchen's line-drive double into the left-field corner. McCutchen took third on Pedro Alvarez's ground out and scored when shortstop Starlin Castro misplayed Gaby Sanchez's grounder for an error.
Jackson pitched five innings and allowed two runs on three hits while walking one and striking out five.
