ST. LOUIS -- Jake Elmore could get used to this big league travel thing.

The D-backs rookie, who was called up from Triple-A Reno on Saturday, got his first taste of how a Major League team travels. Rather than an early morning day of the game flight on a commercial aircraft, the team flies on a chartered jet and its bus pulls right up to the jet instead of going through the airport.

"Free food and you get your own row," Elmore said.

And unlike in the Minor Leagues where players have roommates, at the Major League level players get their own rooms.

"My mom called and asked me who my roommate was," Elmore said. "I told her, 'Mom, we get our own rooms.'"

After a whirlwind weekend, Elmore is starting to settle in a little more.

"I'd say probably one of the bigger adjustments is the crowd noise," he said. "I remember my first AB and I got up and it was 3-1 and they're trying to rattle the pitcher so they put 'scream' up on the scoreboard and then all of a sudden 34,000 people are screaming and you just hear this dull roar the entire time you're hitting, so that's an adjustment."

One he's happy to make, though.

"It's everything that I imagined," he said. "You work your whole life to get here, and when you get here, you hope you're not disappointed and I'm not disappointed, not one bit."

Saito lands on 15-day DL with strained hamstring

ST. LOUIS -- D-backs reliever Takashi Saito was placed on the 15-day disabled list Tuesday with a strained left hamstring and left-hander Mike Zagurski had his contract selected from Triple-A Reno.

Signed as a free agent during the offseason, Saito has spent more time on the DL than on the active roster. He missed the first 93 games of the season with a calf injury and an upper respiratory infection.

After compiling a 6.14 ERA in 10 appearances, he began to experience discomfort in his hamstring.

"He's had a hard time staying healthy all year," D-backs manager Kirk Gibson said.

Zagurski was designated for assignment Aug. 11. While he was waiting to clear waivers, the D-backs called Zagurski Sunday night and told him with Saito hurting they would bring him back to the big leagues, provided he cleared waivers Monday morning.

Zagurski cleared and flew to St. Louis on Monday night.

"It's part of the game," said Zagurski, who has a 6.18 ERA this year. "I wasn't pitching very well, they got some new arms in there, it's kind of how the game works."

In an effort to improve Zagurski's effectiveness, Gibson said he planned on using him differently this time around. Rather than have him pitch full innings, he will be asked instead to get a left-handed hitter out or to turn around a switch-hitter that is weaker from the right side.

"Against certain guys in the lineup, he's probably a better matchup," Gibson said. "We've asked him to do more of that. We'll look for more specialized stuff."

Worth noting

• For the first time since he was acquired July 29 from the Astros, third baseman Chris Johnson was not in the starting lineup.

Johnson has hit .286 with five homers and 18 RBIs for the D-backs since the trade.

"You could see he was dragging a little bit," Gibson said.

Rookie Ryan Wheeler started in Johnson's place.

"I've been wanting to get Wheels in there, but Johnson was on a pretty good roll," Gibson said.

• Right-hander Josh Collmenter saw a doctor about his ulcers Tuesday and should be cleared to resume baseball activities within the next few days.

• Infielder Willie Bloomquist, who is on the 15-day disabled list due to a stiff back, has received some good-natured teasing from his teammates, who are accusing him of sitting out to protect his batting average, which sits at exactly .300.
