KISSIMMEE, Fla. -- Astros first baseman Japhet Amador won't report to camp on Wednesday, or any time soon, general manager Jeff Luhnow said. Amador is in Mexico with a family emergency.

"He's not going to be here, and we don't know what the next steps are with him," Luhnow said. "For now, he needs to spend some time with his family, so he won't be showing up here today. Other than that, we expect everybody else to be here."

Amador, a 6-foot-4, 311-pound slugger who signed out of the Mexican League last year and played in the Arizona Fall League, was going to compete with Jesus Guzman, Brett Wallace, Jonathan Singleton and Marc Krauss at first base.

"When things happen to your family, you tend not to think about next steps," Luhnow said. "We're going to give him the time that he needs, but right now we're proceeding as if he's not going to be here during Spring Training.

"He was one of the players that was going to be in the mix for first base, but we have several others here who are going to compete hard for the position, and we'll find the right guy or pair of guys."

Crain awaiting results of MRI on strained calf

Jesse Crain suffers calf injury during workout

KISSIMMEE, Fla. -- Astros relief pitcher Jesse Crain was awaiting MRI results after suffering a strained right calf in the weight room Tuesday.

Crain, who expected to miss the start of the season while recuperating from arm surgery performed in October, said he was stepping onto a box during a workout and felt something strange in his calf. The results of the MRI are expected Thursday.

"It went without warning or anything," said Crain, who's wearing a protective boot on his foot. "It felt like I got hit by a ball. I thought someone threw something at me at first. I realized it was my calf. Hopefully, it was just a strain, but we'll see what the doctor says tomorrow."

Minor Spring Training muscle injuries are nothing new to Crain, who had a groin strain and oblique strain last spring. Crain has yet to throw off the mound and is recovering from biceps tendon surgery.

"Obviously, at this point, I don't want it to happen, but it's nothing I'm worried about," he said. "We're going to dictate our throwing program around it. Today, I threw off a knee. We're able to still get work in, so I'm not losing any ground in that sense.

"I always say things happen for a reason, and hopefully this will be something that doesn't cause me to rush back. I don't know what the prognosis is going to be. As long as I can get some throwing in, it won't set me back at all."

Crain was an All-Star in 2013, posting a 0.74 ERA in 38 games with the White Sox, striking out 46 and walking only 11 in 36 2/3 innings -- including a 29-inning scoreless streak. He didn't pitch after being traded to the Rays on July 29 because of the injury.

"He came in feeling better this morning," Astros general manager Jeff Luhnow said. "It was sore, so we're going to modify his throwing program a little bit in light of that. We'll know more information the next couple of days, but that will be some sort of setback. We'll continue to try and get him to work on his arm strength, but we'll keep the calf injury in mind."

Cosart happy to have brothers close this spring

HOU@SEA: Cosart limits Mariners over five strong

KISSIMMEE, Fla. -- Astros pitcher Jarred Cosart got a little help from teammate Brett Oberholtzer to send both of his younger brothers to college in Florida.

At the suggestion of Oberholtzer, Jake and Jansen Cosart are both enrolled and playing this spring at Seminole State College in Sanford, which is about 50 miles north of Kissimmee. Oberholtzer pitched at Seminole State before getting drafted by the Braves in 2008.

Last year, Cosart and his father went with Oberholtzer to eat, and Oberholtzer asked about Cosart's brothers. Jake was a freshman pitcher at Duke who was looking to transfer, and Jansen was an infielder and senior at Clear Creek High School in League City, Texas.

"They went through a staff change at Duke and I said, 'Well, the junior college I went to is always looking for guys like this to transfer,'" Oberholtzer said. "The weather and facilities are amazing, and it's 40 miles down the road. I basically told his dad, 'Hey, if they're serious about looking into a junior college, there really is no better place than Florida.'"

Both of Cosart's brothers flew to Florida to work out at the college, and they eventually enrolled.

"They flew out there for a visit the next week and loved it," Cosart said. "It's pretty cool how it worked out. My family and I were really thankful, especially that they're enjoying it so much and, obviously, the opportunity for them was huge."

Now his brothers are so close, the Cosart boys hope to spend some time together this spring.

"It will be easier when we get the game schedule going and I know when I'm going to be throwing," Cosart said. "It's great they're at this school. They can always call me and they talk to Obie and [pitcher Josh] Zeid and some of the other guys I'm close with. It's great for them. They'll be out here at some point this spring, because that's their ultimate goal -- to play in the big leagues."

Porter expects players to adhere to conduct code

Porter, Astros discuss competition in camp

KISSIMMEE, Fla. -- When manager Bo Porter addressed the pitchers and catchers on the field prior to Wednesday's workout, he could be overheard raising his voice and telling his team their actions were "disrespectful."

Porter was asked about the incident following the workout, and he said it stemmed from the daily 9 a.m. ET meeting, which he calls a "synergistic chemistry lab" for the players. Roger Clemens, special assistant to the general manager, was visiting camp to speak to the club, and not all the players were ready.

"Obviously, as an organization, we're fortunate to have some people like Roger Clemens and Craig Biggio and different people that will come in here over the course of the year and speak to our ballclub," Porter said. "Even that being said, we have the 9 o'clock meeting when it comes to the synergistic chemistry lab.

"That being said, out of respect to your teammates, out of respect to the people that take time out of their day to come out there and try to do everything they can to help this organization, it's the right thing to do to make sure you're dressed and ready and attentive when that person shows up or when it's time for a team meeting."

Porter appointed a handful of veterans to lead a closed-door players-only team meeting each day at 9 a.m. He's not in the meetings, but he walked Clemens into the clubhouse and didn't like what he saw from some players.

"From a respect standpoint, you should give them that respect," he said.

Pitcher Brett Oberholtzer said Porter brings the passion every day.

"As a manager, you have to be that way I feel like," he said. "With a younger ballclub in the Major Leagues, it works."
