Pacheco's versatility a boon to Rockies

ATLANTA -- Although first baseman Jordan Pacheco was charged with two errors -- one fielding, one throwing -- on one play in the first inning of Monday's 6-1 loss to the Rockies, manager Jim Tracy said that the mistakes were aberrations.

After playing 13 of his 24 games at first base in 2011, Pacheco has played the bulk of his games at third this season.

"He looks much more comfortable and much more confident over there," Tracy said, crediting the improvement to the work Pacheco put in.

Although Pacheco had a rough first inning in the field, he went 1-for-3 at the plate, extending his hitting streak to a career-high 12 games.

Pacheco has played in 104 games this season and is hitting .311 with three home runs. Though there might be hope that he could one day hit more home runs, Tracy doesn't want Pacheco to change his swing at all.

"I promise you this: We're not going to ask this guy to hit more home runs," Tracy said. "I don't want to hear the suggestions of 'Change your swing, let's see if we can get him to hit for more power.' I personally feel you're doing this guy a real disservice if you suggest that."

After watching Pacheco for a full season, Tracy is convinced that he has a role with the Rockies and that the versatility he has added will only be beneficial.

"We know that he can catch, we certainly know that he can hit," Tracy said. "I think we've covered a lot of miles with this guy. There's no doubt about that."

Scahill, McBride to join Rockies on Wednesday

ATLANTA -- With the season completed for Triple-A Colorado Springs, the Rockies announced on Tuesday that right-hander Rob Scahill and third baseman/right fielder Matt McBride will be called up and join the team in Atlanta on Wednesday.

Scahill, the Rockies' eighth-round pick in 2009, will be making his Major League debut. He pitched all season in the Colorado Springs rotation, going 9-11 with a 5.68 ERA. He struck out 159 and walked 74 in 152 innings.

Manager Jim Tracy said he will try to get Scahill in a game quickly to get his feet wet. After that it will be determined whether Scahill will be used in a piggyback role or as a more traditional reliever.

"I think settling a young kid in is really important instead of just throwing him to the wolves," Tracy said. "I don't want to feel like we're doing that to him."

McBride made his Major League debut on Aug. 4, against the Giants. He played in nine games, hitting .200 with two RBIs, before being sent back to Triple-A.

Colorado Springs manager Stu Cole and hitting coach Rene Lachemann will also be moving up to the Majors for the final month of the season.
