(AP) - Colorado Rockies manager Walt Weiss told rookie Trevor Story when he reported to spring training that he had a chance to win the starting shortstop job with veteran Jose Reyes on leave while facing legal issues.

Then, he sat back and wondered how the 23-year-old would handle his opportunity.

''You see young players go either way. Sometimes it's too much for them at an early age,'' Weiss said. ''Trevor went the other way. He elevated his game. I never saw the game get too fast for him in spring training. It's nice when pressure brings out the best in people.''

Nobody in major league history ever had a first week like Story did: a record seven home runs in his first six games, including homers in his first four starts. He'll try to add to that total when the Rockies (3-3) open a three-game series against the San Francisco Giants on Tuesday night at Coors Field.

''It has been fun so far,'' Story said Sunday after hitting a solo shot in Colorado's 6-3 win over San Diego, giving him 12 RBIs and putting him on pace for 189 home runs and 324 RBIs.

OK, that won't happen. But that's the kind of start Story had in his first week in the majors, when just about every day he was doing something nobody had ever done in the history of the game.

Of the 27 players in the 500-homer club, Willie McCovey needed the fewest games - 18 - to reach seven home runs in 1959, according to STATS.

Barry Bonds needed 38 games. Hank Aaron needed 49, Babe Ruth 68 and Alex Rodriguez 77.

Cooperstown already has Story's helmet and batting gloves.

''They asked for the bat,'' Story said, ''but I couldn't give up the bat.''

Story, who averaged 14 home runs in his five minor league seasons, has no explanation for his sizzling start other than he's locked in at the plate, where he said, ''I just clear my mind, compete with my eyes and react with my hands.''

The Giants (5-2) have had plenty of success hitting the ball out of the park, too. They homered eight times while taking three of four from the Los Angeles Dodgers over the weekend and have hit one in their first seven games for the first time since 1913.

San Francisco fell behind 4-0 in Thursday's series opener before winning 12-6 and overcoming a five-run deficit in the first inning to win 9-6 on Sunday, when Buster Posey, Brandon Belt and Angel Pagan went deep.

Posey went 7 for 14 in the three full games he played.

''Throughout the lineup, we have guys who can drive the ball,'' manager Bruce Bochy said. ''We're not going to rely on the long ball, but it certainly helps.''

Jeff Samardzija will be tasked with keeping Story and the rest of the Rockies (3-3) within the Coors Field walls. He's allowed a homer in nine of his last 10 starts, including his Giants debut Wednesday in which he walked three and gave up three runs through 5 1-3 innings of a 4-3 loss to Milwaukee.

The right-hander said he expects more of himself.

''I thought I was great out of the stretch,'' Samardzija said. ''Made some big outs. It was just out of the windup, man, falling behind in the count, putting the leadoff runner on and just asking for a day of fighting out there when that happens.''

He is 2-0 with a 2.01 ERA in three career starts against the Rockies and has posted a 1.88 mark over 14 1-3 total innings at Coors.

Tyler Chatwood gets the ball for Colorado after allowing two runs - one earned - in 6 1-3 innings of Wednesday's 4-3 win over Arizona. The right-hander, though, allowed three of San Francisco's six homers and walked four in the Giants' 12-10, 11-inning road victory the last time he faced them April 23.
