PHOENIX -- As of Friday afternoon, D-backs catcher Miguel Montero and pitcher Trevor Bauer had not met to discuss how they could better be on the same page in Bauer's future starts.

"He hasn't come to me, so I guess I have to go to him," Montero said.

Montero was out of the lineup Friday, so he planned on sitting with Bauer during the game to talk things over. Bauer repeatedly shook Montero off in his last start Tuesday and suggested Thursday that he would sit down with Montero to discuss it.

"I've got a lot of things to worry about right now," Montero said. "I've got 12 other pitchers that I have to take care of, too. I'll find a good time to talk to him and find out what's cracking."

Montero said he does not have a problem with Bauer shaking him off during a game, nor does he think the rookie should defer to him on everything.

However, the veteran would like to at least have a talk with Bauer before his starts to have an idea of what kind of game plan Bauer does have.

"I understand he pitches his way, but at the same time we need to have a plan," Montero said. "If the guy's a good fastball hitter, yeah, you can throw the fastball, but where? It's just things we need to talk [about]. We need to have a little game plan. It's not like we're going out there, 'This is the way I'm going to pitch and I'm going to throw it like that.' I mean we need to have a little game plan. Guys here make better adjustments than Double-A and Triple-A."

Montero was asked if he had caught pitchers before who wanted to call their own game, and he cited Livan Hernandez and Randy Johnson.

"It was Livan Hernandez -- he was a veteran of 15 years in the league so I think he had a better idea than me because it was my rookie year in the big leagues," Montero said. "Even that being said, we'd talk about it. We talk about how we're going to do things, so that way I had a little plan about how he liked to do things. I had Randy. Who's Randy? A Hall of Fame guy that I had to catch, right? We talked about it before the game as well. We talk, we see, we had a game plan. It makes things easier for me and for him."

If Bauer's first two starts had gone better, this might not be as big of a topic of conversation.

"As long as the results are good, everything is good," Montero said. "But when things don't work out the way we all expect, it gets a little frustrating."

Tests show CEO Hall may need further treatment

PHOENIX -- D-backs president and CEO Derrick Hall's recent prostate-specific antigen (PSA) test showed an increase from his last one and could indicate he will need to undergo further treatment.

Hall was diagnosed last September with prostate cancer and had his prostate removed in November.

The previous PSA test showed undetectable amounts, but this latest one showed the level had risen.

"[Thursday] I got the phone call from the doctor 10 minutes before first pitch," Hall said. "He told me that my PSA number went up, which is never a good sign after you've had prostate surgery. It means there could be some cells there that could require further treatment, likely radiation. So we'll wait three months and take the test again."

Hall went public with his battle last year in hopes of increasing awareness for testing. He posted an update on his Facebook page and sent out a message on Twitter to update fans on his latest test.

"I shared it to encourage others to get tested," Hall said. "I'm not worried, we'll handle it. It may be nothing, but the likelihood of some kind of future treatment is more likely than not. We'll continue to monitor it, but again it gives me a chance to remind men of all ages to get tested."

First D-backs alumni game slated for Sept. 15

PHOENIX -- The D-backs will host their first alumni baseball game on Sept. 15.

The event will highlight the Alumni Day festivities, with former D-backs players taking the field shortly after the conclusion of the D-backs game against the Giants, which begins at 5:10 p.m. MST.

The players will be introduced prior to the game with the Giants. Among the players scheduled to attend are Luis Gonzalez, Steve Finley, Matt Williams, Reggie Sanders, Tony Womack, Devon White, David Dellucci, Mike Fetters, Greg Swindell and Junior Spivey.

Players are subject to change and a more complete roster will be announced at a later time.

The D-backs held a fan vote to determine which retro jersey the team would wear that day, and the winner was the alternate purple jersey worn from 1998-2002. The jersey features the word "Arizona" across the chest.

In addition to the alumni game, the first 20,000 fans through the gates that day will receive a Matt Williams bobblehead courtesy of Chase. Williams, who played with the D-backs from 1998-2003, is the team's third-base coach.
