He had to spend an extra year in the Minor Leagues because of a logjam in the Arizona outfield, and this year, after he was penciled in as the club's starting right fielder and was having the best spring of any hitter, he suffered a shoulder injury that forced him to start the year on the DL.
Ever since the injury, Quentin struggled to regain his hitting stroke and he was eventually sent to Triple-A Tucson just prior to the All-Star break. After hitting .419 there he was called back up and was in the process of legging out a double on Wednesday night when he injured his hamstring.
"It had been sore, but I really felt it last night," he said.
While the club thinks he will likely be ready to play quicker than two weeks from now, it couldn't afford to play a man short for a week as it battle its division rivals, the Dodgers, this weekend.
"Obviously luck has not gone his way," Arizona general manager Josh Byrnes said. "He's a guy that cares very much about his performance and the team's performance. He just seems to be the guy that can't catch a break this year."
Despite his struggles this year, Byrnes said Quentin remains in the organization's long-term plans.
"No doubt," Byrnes said. "Very, very good player. Other than this year, when some things worked against him, he's been a guy that's always hit."
Knows the feeling: First baseman Tony Clark said he can understand what Quentin has been through this year. The veteran missed the entire 1991 season, his second in pro ball, after undergoing back surgery.
"I can empathize wholeheartedly with it, having been injured early in my career while trying to establish myself," he said. "I can appreciate the coming back and trying to hit 30 home runs in April and trying to hit five-run home runs to prove to everybody that you're capable of playing at this level. At the same point, you find a way to push through and inevitably, when you come through the other side you're stronger and better equipped than you were when you started. There's a level of confidence that you gain by persevering through difficult times."
Quick fix: Major League teams travel with some extra uniform numbers -- some for pitchers and some for hitters -- that they can pull out if a player is called up while the team is on the road, which is how Justin Upton wound up wearing No. 10.
As for the name on the back of the jersey, in each city there is a seamstress that is available for just such emergencies.
You can count on me: Second baseman Orlando Hudson credits veterans like Carlos Delgado for showing him the ropes when he was coming up through the Blue Jays system and he plans on doing the same thing with Upton.
"You have to stay on them," Hudson said of rookies. "They come up from the Minor Leagues and they don't really know how this game works. You've got to stay on their butts all the time. Got to let them know that you got here because you did something right. Now you've got to stay here for 20 years."
Up next: The D-backs head to Los Angeles to open a three-game series with the Dodgers on Friday.
Arizona is 1-2 this year at Dodger Stadium and was 2-7 there last season.
"It's really the one team that's handed it to us pretty much every time," D-backs manager Bob Melvin said. "We played a nice game the first game over there the last time and then they backed it up with two real good games against us. They're a good team. They've matched up well against us; they've played well against us. So we need to go in there and kind of change the mindset. So yes, it is a big series."
The D-backs will send Doug Davis (7-10, 4.11) to the mound in the opener against Chad Billingsley (7-1, 3.65).
