"Chris Iannetta hit a game-winning grand slam Monday night. Tuesday night, he clubbed a solo homer into the second deck at San Diego's Petco Park. Given the heavy night air, that's no easy task. His six home runs lead major-league catchers, but Iannetta swears he's not a home run hitter. "I just go out there and try to find the barrel and hit line drives," he said. "The day I start trying to hit home runs is the day I won't get any results. I can't do that. Pitch location and all of the other things dictates home runs." After a terrible start, Iannetta is slowly starting to come on. Though he was hitting just .200 for the Rockies entering Wednesday, he's made his hits count. After beginning the season 0-for-9 with runners in scoring position, he's come through lately in the clutch, going 4-for-5. Rookie daze. Reliever Matt Daley got a sweet-and-sour taste of the big leagues Tuesday in San Diego. He was heartened that manager Clint Hurdle had enough confidence to bring him back for the 10th inning after he had pitched a solid ninth. He was stung when he walked a batter and gave up a game-winning hit to Brian Giles. It was the first hit allowed by Daley in his brief major-league career. "Overall, it gave me a lot of confidence that (Hurdle) had faith in me and the way I'd been pitching the last few games," said the 26-year-old rookie. Daley knew the pitch he threw to Giles was trouble. "I knew it immediately, the moment I let it go," he said. "It was a fastball that just caught way too much plate and was up in the zone.""
