Greinke remains on track after rehab start

MILWAUKEE -- Zack Greinke remained on track for an early-May Brewers debut after throwing 54 pitches in a rehabilitation start for Triple-A Nashville on Sunday.

Greinke, on the disabled list because of the cracked left rib he suffered in Spring Training, allowed two runs on three hits in 2 2/3 innings for Nashville against Omaha. He walked one and struck out two in his second of three scheduled Minor League starts.

"Maybe the velocity was still there, but the control wasn't that sharp," Greinke told the Nashville Tennessean. "When that happens the control has to get better, and it didn't.

"Through almost the whole first two innings I felt real good. But they had a couple long at-bats and I hadn't really had any real long innings yet."

He will make at least one more start with Nashville on Friday, against Albuquerque. If he continues pitching every five days, Greinke is on track to pitch for the Brewers in Atlanta on May 4, and -- very tentatively -- at Miller Park against the Padres on April 9.

Greinke had previously pushed to re-join the Brewers earlier.

"Not anymore," manager Ron Roenicke said with a smile, intimating the two had a chat last week. "To bring back Zack a week earlier or five days earlier and really not have his arm strength, it makes no sense to me. We need this guy for the long haul.

"When he's back here, I want him to be solid for the rest of the season, hopefully getting us into the playoffs. That's when I want him good."

Marcum's dad doing well after major surgery

MILWAUKEE -- Shaun Marcum pitched against the Astros Saturday night with his Little League coach in the back of his mind.

Pat Marcum is Shaun's dad -- and former coach -- and he's coming off a tough week. He underwent triple bypass surgery in Kansas City on Tuesday, the day after Shaun pitched a gem in Philadelphia.

"My mom and dad both told me not to come home," Shaun Marcum said. "They didn't think it was a big deal."

Brewers manager Ron Roenicke, pitching coach Rick Kranitz and teammate Randy Wolf convinced Marcum otherwise, so the Brewers placed him on the bereavement list and he traveled home to Kansas City. Pat Marcum was about 30 minutes into surgery when Shaun arrived, and the two spent the next two days together.

Shaun Marcum rejoined the team on Friday and allowed four runs in six innings against the Astros in a no-decision Saturday night, a few hours after his dad was released from the hospital.

He was burned on two misplaced pitches, an 86 mph fastball to Carlos Lee that was supposed to be high and tight and instead sunk low, right into Lee's hitting zone, and a changeup to Hunter Pence that was supposed to be low but instead was way up.

Lee hit his mistake for a two-run home run and Pence for a long solo shot, and it took a Brewers rally in the bottom of the ninth inning to take Marcum off the hook for a loss.

Much more importantly, dad was resting comfortably at home.

"Everything is good on his end," Marcum said. "My parents, if it weren't for them traveling me around the country when I was little, I don't know if I would be here right now. I give them a lot of credit for doing that for me."

Hart could return to Brewers on Tuesday

MILWAUKEE -- Brewers right fielder Corey Hart is scheduled to play all nine innings for Triple-A Nashville on Monday and could be ready for his season debut with the Brewers the next night.

The Brewers will make that decision after consulting with Hart following Monday's game, and could decide to delay his return from a Minor League rehabilitation assignment until Wednesday. Hart missed all of Spring Training with a left rib-cage strain.

"We'll see how [Monday] goes," Roenicke said. "If his at-bats are good and he feels his timing is there, we may try to do something."

When Hart returns he will quickly resume his role as the regular right fielder. The Brewers will have to clear a roster spot, and both Erick Almonte and recently-promoted Brandon Boggs are out of Minor League options. Mark Kotsay, who has made most of the right-field starts in Hart's absence, would return to a reserve role.

"It's going to allow that bench to be stronger," Roenicke said.

Ash to keep an eye on Admirals on Monday

MILWAUKEE -- Brewers assistant general manager Gord Ash will have an eye on two local sporting events Monday night. He'll be at Miller Park with the baseball team, of course, but he will also be interested in the result of the American Hockey League playoff game at Milwaukee's downtown Bradley Center.

Ash and Brewers principal owner Mark Attanasio are minority owners in the local hockey franchise owned by Haris Turer, who in turn is a minority owner of the Brewers. The Milwaukee Admirals are the top farm club for the NHL's Nashville Predators, and hold a 3-2 series lead over the Texas Stars heading into Monday night's Game 6.

"Hopefully they advance so I'll get to see some of the next round," Ash said.

The Brewers and his family responsibilities keep Ash away from the rink more than he would like, but he follows the Admirals from afar. In January, the Brewers' front-office staffers, doctors, athletic trainers and scouts took a break from their medical symposium to attend a game at the Bradley Center just as the Admirals started getting hot.

They've been hot a lot.

"They set a record for consecutive years with 90 or more points, they set a record for consecutive number of years in the playoffs, so they've done quite well," Ash said. "I think the relationship with the Predators has been advantageous, but this is very similar to operating a Triple-A baseball team. You're not in charge of your roster, and you fall victim to injuries at the 'Major League' level. They lost their goalie, and the guy they brought in to replace him has done a great job.

"It's a niche sport to some degree, but we have a very strong group. They have a lot of fun, and like most sports of that genre, it's not all about the game, it's about the experience."
