Braves giving Gosselin time at second base

ATLANTA -- Braves manager Fredi Gonzalez has not said Tommy La Stella has lost his role as the club's everyday second baseman. But if actions speak louder than words, Gonzalez has at least created reason for debate by utilizing Phil Gosselin as his starting second baseman during the final two games of this weekend's series against the A's.

"Sometimes you talk about bringing that little bit of energy, and [Gosselin] has done that," Gonzalez said. "This is nothing against Tommy. I'm sure he'll run in there again soon enough."

As he walked through the clubhouse on Sunday, La Stella said he is healthy and unaware of why he was not in the lineup for the final two games of the A's series. The 25-year-old rookie has been a regular in the Braves' lineup since being promoted from Triple-A Gwinnett during May's final week. La Stella hit .292 with a .371 on-base percentage in the 43 games he played in before the All-Star break. But he has batted .245 with a .324 OBP in 26 games since the break.

When comparing the two rookie infielders, Gosselin has the advantage in the defensive and baserunning departments. In addition, he helped himself by recording two-hit games when he was given a chance to start the first two games of the A's series. His sixth-inning homer on Friday night was the first of his young career, which was enriched when he was promoted from Gwinnett during the final week of July.

"He's swinging the bat well," Gonzalez said of Gosselin. "We'll keep riding him out a little bit and see where he goes."

Gonzalez said he's not planning to platoon the two rookie infielders, and he seemingly proved this when La Stella sat as the A's started right-hander Sonny Gray on Saturday and left-hander Jon Lester on Sunday.

Fredi: Teheran's pickoff move best by righty

ATLANTA -- After seeing their players victimized by Julio Teheran's effective pickoff move this week, Dodgers manager Don Mattingly and A's manager Bob Melvin both suggested that Teheran balks with his move to first base.

As all of the great pickoff artists of the past will attest, this is an accusation Teheran will hear numerous times if he continues to be as successful as he has in the pickoff department.

Braves manager Fredi Gonzalez obviously doesn't agree with the opinions expressed by Mattingly and Melvin.

Instead, Gonzalez says Teheran has "maybe the best [pickoff move] I've ever seen for a right-hander. He's got quick feet and he's got a short throw. Some guys have quick feet and it takes them a long time to get the ball to first base. But that's not the case with him. He has both quick feet and a short arm."

After recording eight successful pickoff attempts last season, Teheran has found opposing baserunners being more cautious with him in 2014. He notched just two pickoffs through his first 24 starts of the season. But he nabbed two Dodgers -- Carl Crawford and Yasiel Puig -- on Monday and then made A's outfielder Josh Reddick his latest victim on Saturday night.

"That was a balk," Melvin said after Saturday's game. "That's a balk. Buckle your knees, it's a balk."

Teheran has recorded 13 pickoffs since the start of the 2013 season. No other right-handed pitcher has recorded more than six.

"I know that I have quick feet," Teheran said. "Sometimes, I feel I don't need it. But when I see them getting a big lead, that's when I try to make my best move."

Worth noting

• Shae Simmons opened his rehab assignment by tossing a scoreless inning for Gwinnett on Saturday night. Simmons will make at least one more appearance on Monday. Gonzalez said the club will then determine when it would be best to activated the right-handed reliever, who has been sidelined since July 26 with a right shoulder strain.
