Estrada throws simulated game, nearing return

KANSAS CITY -- After weeks of bad news on the injury front, Brewers manager Ron Roenicke offered a triple dose of good news on Tuesday.

Pitcher Marco Estrada, on the disabled list with a right groin strain, threw a 30-pitch simulated game at Kauffman Stadium and is on track to begin a rehabilitation assignment with Triple-A Nashville on Sunday, Roenicke said.

Shortstop Cesar Izturis (left hamstring) and first baseman Travis Ishikawa (left rib-cage) are not far behind. The Brewers are still formulating a plan for both players.

"It's nice when you know those guys are getting close to joining us again," Roenicke said. "We're still a ways off, though."

The tentative plan, Roenicke said, is for Estrada to throw about 60 pitches on Saturday and make one more Minor League start before the Brewers consider him for reinstatement from the DL.

June 26 looks like a possible date for Estrada's return to the Brewers' rotation.

Brewers' supplemental pick set to sign with team

KANSAS CITY -- Mitch Haniger, the Cal Poly San Luis Obispo outfielder selected by the Brewers with the 38th overall pick in the First-Year Player Draft, said via his Twitter account that he was set to sign with Milwaukee on Thursday.

Haniger would have to pass a physical exam before the deal is official, so the Brewers have made no announcement.

A baseball source confirmed late Monday that the sides have a tentative agreement, and said Haniger would get a $1.2 million bonus. That's slightly below Major League Baseball's $1.359 million recommendation for the 38th overall selection.

The Brewers already signed their other two picks from Day 1 of the Draft, prep catcher Clint Coulter for $1.675 million and college outfielder Victor Roache for $1.525 million. Those players went 27th and 28th overall.

The original plan had the Brewers introducing all three players together at Miller Park, but Haniger's trip was delayed because he had a final exam at Cal Poly.

Haniger, 21, is a 6-foot-2, 215-pound center fielder. He was the runaway Big West Conference leader in home runs (13), RBIs (64), slugging percentage (.626) and total bases (132).

He hails from the same school that produced Brewers outfield prospect Logan Schafer, whom Haniger considers a friend.

"I had heard from my advisors that [the Brewers] were one of the teams real interested, but once Victor Roache got taken in the late first round, I thought there was less of a chance they were going to take me at 38," Haniger said on Draft night. "But it's awesome, it was a great feeling. Words can't describe it."

Last call

• Roenicke still plans to use this week's slate of Interleague Games in American League parks to give his regular position players a day off their feet. But since the Brewers were coming off an open date, young Taylor Green drew the first start at designated hitter on Tuesday.

Ryan Braun, third baseman Aramis Ramirez, right fielder Corey Hart and second baseman Rickie Weeks are all candidates to be the DH in upcoming games, Roenicke said.
