Towers jelling with new boss La Russa

PITTSBURGH -- It has been more than six weeks since Tony La Russa joined the D-backs' organization as Chief Baseball Officer, and general manager Kevin Towers says he is pleased with how it has gone.

"I've enjoyed being around him," Towers said of his new boss. "He's a good guy. He's been around the game a long time, been around a lot of championship clubs. I love sitting in the [GM's] box and talking to him. He's easy to talk to. We sit and talk baseball. I enjoy that."

Prior to La Russa's hiring, Towers reported to team president/CEO Derrick Hall.

Towers said he had discussed with La Russa what options the D-backs had at the non-waiver Trade Deadline and kept him looped in when moves like the promotion of shortstop Nick Ahmed happen.

"To me the dialogue is good; we communicate well," Towers said. "It really hasn't changed much. It's just another layer. He's been very supportive. I don't know how he feels, but to me it's business as usual."

Expect the D-backs to retool rather than rebuild their roster at the Trade Deadline as they see themselves as a team that can be right back in the thick of things next year.

"We've just got to get healthy," Towers said. "I don't think we're that far away. We just had some horrible luck this year. A bad start and some horrible injuries."

Gibson rests Prado, Parra in finale vs. Bucs

PITTSBURGH -- D-backs manager Kirk Gibson can sense the frustration mounting in his club, and his lineup for Thursday's finale against the Pirates reflected that frustration.

Gibson rested two regulars in third baseman Martin Prado and right fielder Gerardo Parra, both of whom committed errors in Wednesday night's game.

"There's not a message," Gibson asked when asked if he was trying to send one with the lineup. "Last night, you could see guys are overly frustrated. We're in the middle of a road trip, and other guys are preparing as well, so we gave a couple of guys a day off today. And get some of the guys in there, get them an opportunity. There will be some other guys getting some days off in the upcoming days as well."

Parra, a Gold Glove defender in right, had played in 83 of the team's 86 games entering Thursday and was mired in a slump at the plate with just one hit in his past 21 at-bats.

Prado, meanwhile, is just 4-for-20 on the trip and has performed below expectations.

"I think he's frustrated, yeah," Gibson said of Prado. "He's been pressing hard. Everybody wants to do good. That was one of our poorer games that we played last year, I thought. We'll get him a day off today and he'll be back in there for the Atlanta series. These guys care a lot. They try to overthink things. They don't mean to, but it happens. I'm just trying to give them a break, give the other guys an opportunity."

Worth noting

• The D-backs' No. 1 pick in last month's Draft, right-hander Touki Toussaint, made his professional debut in the Arizona League on Wednesday.

Toussaint tossed one inning and allowed a home run while walking one and striking out three.

• D-backs scouting director Ray Montgomery has interviewed for the Padres' vacant general manager's job.

• Injured left fielder Mark Trumbo, who is on a rehab assignment in the Arizona League, hit a two-run homer Wednesday and is 3-for-6 with a double, a homer and four RBIs in two games. Wednesday marked the first time he had played in the field since his injury, a stress fracture in his left foot that put him in on disabled list on April 24.

• Second baseman Aaron Hill will most likely get a day off Friday with Didi Gregorius starting at second and Nick Ahmed getting the nod at shortstop.

• MLB.com's Jesse Sanchez reported that the D-backs signed outfielder Juan Carlos Araujo for $215,000 and third baseman Mailon Arroyo for $350,000 prior to the July 2 International Signing Deadline. Both players are from the Dominican Republic.
