The jump from Triple-A to the Major Leagues is a big one, and Rockies rookie left-hander Tyler Matzek is starting to work out what he needs to do to make up the difference.
Matzek, who will get the ball against the D-backs on Saturday, has had an inconsistent season, but he has looked better in his last two outings.
"Just starting to get the feel of things. Starting to feel a bit more comfortable out there," he said. "The nerves are starting to go away and I'm starting to settle in. I really think I'm starting to figure out what's needed to be successful."
After his ERA reached a season-high 5.50 following a six-inning, five-run outing against the Padres on Aug. 13, Matzek has tossed a pair a pair of quality starts. Most recently, he gave up only two runs in seven innings against the Giants.
"[I am] learning my strengths and sticking with them, how to attack different hitters, stuff like that," Matzek said. "There's a bunch of little, little things."
His Saturday opponent, Vidal Nuno, has also pitched well of late, going seven and 7 1/3 innings in his last two starts, respectively.
The D-backs are 1-8 in games Nuno has started, winning their first game behind him after his last outing on Aug. 23.
Rockies: Weiss tries to correct road woes
When the Rockies play at home, they hit like All-Stars. But when they leave the friendly confines of Coors Field, they struggle.
At home, the Rockies are hitting .317 as a team with an .884 on-base-plus slugging percentage, entering play Friday. For comparison, reigning American League MVP Miguel Cabrera has an .865 OPS this season.
But those numbers fall to .231 and .645, respectively, when the Rockies are on the road.
"That's the million-dollar question," manager Walt Weiss said. "It's something we've had to deal with in Colorado since we've had a club."
Weiss said that while Coors Field, the most hitter-friendly park in the Majors, contributes to the lofty numbers, his players need to alter their approach to have the same success on the road.
"It's well documented that Coors Field is a great place to hit, but I think it does come down to approach," Weiss said. "You've got to be able to cover the outer half of the late, two-strike approach has to be sound. You have to be able to hit the ball from line to line.
"If swings get big, as they have at times, then that's when you get exposed on the road."
D-backs: Reimold joins crowded outfield
The D-backs claimed outfielder Nolan Reimold off waivers from the Blue Jays on Thursday, but he may not have much time to see the field often.
Not only is Reimold joining the team less than a week before rosters expand on Sept. 1, but the D-backs also have a pair of outfielders set to come off the disabled list shortly.
Manager Kirk Gibson said both A.J. Pollock and Cody Ross could possibly return to the D-backs in the next week.
Reimold said he had a tough time getting into a rhythm with the Blue Jays.
"I started out real well. Then I had a little setback, and when I came back I got a lot of scattered at-bats and didn't get comfortable again," he said. "It was a bad 20 at-bats and see you later. I'm happy to be here and get another opportunity and make the best of it."
Reimold hit .212 in (11-for-52) in 22 games with the Blue Jays this season. He was with the Orioles to start the season while on the disabled list after undergoing his second neck surgery to repair a herniated disk. The Blue Jays claimed him after the Orioles designated him for assignment on July 6.
"It was kind of a whirlwind," Reimold said. "I changed teams for the second time now this year and the second time in my career, too. A lot of packing, moving and learning new names and doing all that kind of stuff."
