Minor Leaguer Mills sent to A's

MILWAUKEE -- The Brewers traded Triple-A left-hander Brad Mills to Oakland on Tuesday for cash considerations, payable in one stack of pennies.

The $1 fee, reported by Ken Rosenthal of MLB Network and Fox Sports, was a technicality of a clause in Mills' Minor League contract with the Brewers, which included an "out" if he was not in the Majors by June 15. The Brewers were required to advertise Mills' availability to the other 29 teams, and if one was interested, Milwaukee had to let him go.

The A's were interested, and plan to add Mills to their rotation as soon as Saturday. The 29-year-old soft-tosser went 4-2 with a 1.56 ERA in 14 appearances, 12 starts, at Triple-A Nashville, including one stretch of 18 1/3 scoreless innings.

"I feel good about a guy getting an opportunity," manager Ron Roenicke said. "If we've got a couple [other] guys that we have in mind to be starters for us, which I think we do, I think any time one of those guys at Triple-A can go to the big leagues is great.

"It's great for us to be able to have this guy as insurance for us, but it's not fair to the player. I mean, I would feel bad if we kept him because we like him and all of a sudden, everybody stayed healthy and we never brought him up and he misses an opportunity for half a year in the big leagues."

Top prospect Jimmy Nelson and fellow right-hander Mike Fiers were both ahead of Mills on Milwaukee's organizational depth chart, and just as important, were already on the 40-man roster. That's why Fiers was promoted to fill a spot in the bullpen last week.

Fiers planned to send Mills a congratulatory text on Tuesday.

"He was pitching. That's the kind of guy he is," Fiers said. "Not a big velocity guy. Similar to me, you've got to pitch. He mixes his pitches well, keeps hitters off balance and throws strikes. He's a pitcher, man."

Brewers being cautious with Gomez

MILWAUKEE -- Carlos Gomez wanted to play, but the powers that be ordered him to rest one more day.

The speedy Gomez, bothered by tightness in his left hamstring, missed a second straight start on Tuesday when the Brewers played the D-backs at Chase Field, but said unequivocally that he would return to the lineup on Wednesday night. He will be bidding to resume a streak of reaching safely in 30 consecutive games, the longest current stretch in the Majors.

Manager Ron Roenicke sidelined Gomez for a second day out of an abundance of caution.

"Yeah, he could have played today," Roenicke said. "The conversation with Carlos was more, 'If you get on base, are you going to steal second? And if you're playing center field and there's a ball in the gap, are you going to go full-go to get it?' And if those things are there and he's not comfortable 100 percent, I feel better trying to at least get him closer to that point. Even though we love him in the batter's box, he depends a lot on his legs. And to not be able to go 100 percent bothers me."

"There's no rush," Gomez said. "He wants me to be 100 percent. I understand. I wanted to play today, and yesterday I could play, too, but he decided to give me the day off.

"It's not like [I have] a tear or I pulled something. It's not that. It's general. I've had an injured hamstring before, and it's not even close. When you pull a hamstring -- you saw Rickie [Weeks] last year -- you go down."

Gomez tried to change Roenicke's mind, attempting to talk -- and run -- his way into the lineup.

"Today I came in early, and I told Ronnie, 'I want to play,'" Gomez said. "They said, 'Let's go see you running.' I was running, giving everything. After that I felt a little bit fatigued, a little tight, but it's not like pain. They said, 'We're going to give you another day, because [we] prefer you to take two days off [instead of] playing not 100 percent and taking a week or week and a half with no stolen bases, only running under control. Take two days, then come tomorrow and give everything you have.'"

Gomez said he will definitely start on Wednesday against Arizona left-hander Wade Miley.

"For sure, no matter what [Roenicke] says," he said with a laugh.

Last call

• This is Mark Reynolds' first visit to Chase Field since the D-backs traded him to the Orioles in December 2010. Reynolds hit 121 home runs over four seasons in Arizona (2007-10) and still lives in the Phoenix area.

"It's awesome, because I get to stay at my house and sleep in my bed," Reynolds said.

• Relievers Jim Henderson and Tyler Thornburg, both of whom are on the disabled list with arm injuries, are expected to remain in Phoenix when the Brewers move on to Colorado. They will get treatment and work out at Maryvale Baseball Park, where the team operates a year-round rehab facility.
