Teheran went 4 2/3 innings against the Phillies on May 7, allowing three runs on four hits, walking two and striking out one. He and the Braves lost, 3-0, but it was still a glimpse into the future.
"I think he knows he can compete up here," Gonzalez said. "Now it's just a matter of getting some experience."
Here's his first chance for more. Outing No. 2 for the game's second best right-handed pitching prospect according to MLB.com is scheduled for Wednesday in Arizona. The Braves and D-Backs, who send left-hander Joe Saunders to the hill, are scheduled to start a two-game series at 6:40 p.m. MST at Chase Field.
"I'd like to see what he can do the second time around, now that he got a taste of the big leagues," Gonzalez said. "I've got no doubt in my mind this kid is going to be a big part of our future."
The D-backs split a two-game series with the Padres after a 6-1 win Tuesday night. Before Monday's 8-4 loss, they had won two in a row, snapping a five-game losing skid.
Saunders can't find any luck. At 0-5, he's allowed three runs, two runs and three runs in his last three starts, but took a no-decision and two more losses. Pitching longer in games may help -- he's yet to crack seven innings.
The Braves are coming off one heck of a comeback win against the Astros thanks to Brian McCann. The catcher hit a game-tying, pinch-hit solo home run in the ninth inning, then won it in the 11th inning on a two-run shot. The final was 3-1.
"I've definitely never done that before," McCann said.
As for his catching duties, McCann expects more of Teheran on Wednesday.
"I think his next outing will be even better than his first, especially for me because I now know what he has," McCann said. "The first time I caught him, I didn't call the best game in the world. But knowing what he has and what he is made of, this next outing should be a lot better.
"He's got top of the rotation stuff. He's going to get better and better."
Braves: Jones should be in lineup again
Chipper Jones' right knee had improved enough for him to play Tuesday after two cortisone injections Sunday evening. He finished 1-for-5 in the win, and is expected to play again Wednesday.
"We have a stay of execution," Jones said with a smirk, referring to the possibility of surgery. "Cortisone is a wonderful thing."
Jason Heyward also made his return to the lineup Tuesday. The 21-year-old right fielder had missed the previous six starts because of an inflamed right shoulder.
"It feels the way that it should," said Heyward, who went 1-for-3 with two walks and a stolen base.
D-backs: Galarraga designated for assignment
Armando Galarraga was designated for assignment following Tuesday's game. The right-hander was 3-4 with a 5.91 ERA in eight starts this year, and had walked 22 while fanning 28 in 42 2/3 innings.
"It was kind of a breaking point for us, and we just felt it was time to make a change there," D-backs GM Kevin Towers said.
The D-backs have 10 days to trade, release or outright Galarraga to the Minors.
D-backs manager Kirk Gibson was named an All-Star on Tuesday. He'll join the staff of Giants manager Bruce Bochy on the National League bench.
Braves outfielder Martin Prado was named the National League Player of the Week for May 9-15 after hitting .462 (12-for-26) with seven runs, three home runs and eight RBIs.
Prado also won the NL Player of the Week award for the same week (May 10-16, 2010) last season.
