White placed on 60-day DL with elbow sprain

HOUSTON -- The Astros made a major roster move following Saturday's victory over the Cubs, placing right-hander Alex White on the 60-day disabled list.

White suffered a sprained elbow in Friday's game. White started the game and was scheduled to pitch two innings, but was pulled by manager Bo Porter after one inning when he complained of right elbow soreness.

White was scheduled to be Houston's long reliever.

The Astros also purchased the contract of veteran reliever Edgar Gonzalez from Triple-A Oklahoma City to replace White.

"He will fill that role as the long man out of the bullpen," Porter said of Gonzalez.

White gave up three hits and three earned runs in the one inning on Friday, striking out one and walking one.

"He was only going to go two innings, anyway," Porter said. "You want to get him out and get him treatment."

Martinez swap: Fernando to DL, J.D. recalled

HOUSTON -- The Astros placed outfielder Fernando Martinez on the 15-day disabled list Saturday with a strained oblique. The move is retroactive to March 27.

Martinez was scratched from the starting lineup before Thursday's game and he did not play in Friday night's home game against the Cubs. He has also been bothered by back tightness.

Martinez was examined Friday night for a strained oblique, but no decision was reached. He will be reevaluated Saturday.

Outfielder J.D. Martinez was recalled from Triple-A Oklahoma City to take Fernando Martinez's spot on the roster.

Fernando Martinez, 24, played in 41 games for the Astros last year, hitting .237 with six homers and 14 RBIs. Houston acquired him in January 2012 off waivers from the Mets.

J.D. Martinez, 25, appeared in 53 games for the Astros in '11 and in 113 games last year. He hit .241 last year with 11 homers and 55 RBIs.

Porter leaning on Wright to lead young group

HOUSTON -- First-year manager Bo Porter is looking for leaders in his clubhouse.

Rick Ankiel, 33, who broke into the Majors as a pitcher with the Cardinals in 1999, obviously possesses the criteria.

Porter is also counting on Wesley Wright to be a leader in the bullpen. Wright, although only 28, is the longest-tenured player on the roster, first joining Houston in 2008 after being picked from the Dodgers in the Rule 5 Draft.

With the exception of four starts in 2010, the left-handed Wright has pitched strictly in relief.

"We all like to be looked upon as leaders," Wright said. "Some of us are not vocal. You lead by your actions. I go about my business and try to do it in a way where guys respect what I do. To do the right thing.

"If I see somebody doing something [wrong], I'll pull him to the side. I'm not much of a meeting guy or stand-up-in-front-of-the-team type of person. I'm more of an individual conversation type. I like to be someone this team can count on to help go where we want to go."

The Astros, who start their first year in the American League West this season, are not expected to contend.

"You start looking at standings and what your record is, that kind of gets in the way of what you're trying to do," Wright said. "Be the best you can be on that day and if you take that course, you have a better chance of being successful throughout the course of the season."

Listed generously at 5-feet-11-inches, Wright is one of the game's shortest pitchers and could probably still pass as 20 years old.

"Baseball life flies by," Wright said. "You think you're going to play forever. Then you're getting older and getting older and before you know it, the years have passed and there's a new wave of guys coming in. That's good, a lot of new energy.

"In '08, we were a couple of games out of making the playoffs and last year not even close. I've seen both sides of it. I've seen what a really good team looks like and what it looks like when you're not."
