Gonzalez fills utility role for Astros

HOUSTON -- Lost in the hubbub about starting lineups and pitching rotations is a well-worn roster rule in the big leagues. Every team needs a utility player off the bench.

Marwin Gonzalez currently fits that role for the Astros, and he earned a start in left field due to his versatility for Saturday's game against the Mariners.

"He's played some outfield and it's something we worked on in Spring Training," said Houston manager Bo Porter. "He's been shagging a lot of balls in the outfield, and we have complete confidence in him."

Gonzalez has already played four positions -- shortstop, third base, second base and right field -- this season and has also pinch-run. This will be his first action in left field.

But that versatility alone didn't vault Gonzalez into this spot start. Porter said he's also been impressed with Gonzales' approach at the dish.

"He's had really good at-bats, no matter where we hit him or moved him around the diamond," Porter said. "Just swinging the bat well."

The shortstop is hitting .294 in his last 17 at-bats, including a solo home run on April 20 against Oakland.

He was Houston's starting shortstop for much of the first three months in 2013, starting 50 games until being sent down in June with poor hitting numbers and double-digit errors.

With Jonathan Villar entrenched at short this season, Gonzales' ability to be a baseball chameleon has translated to a prominent bench role.

"When you have a guy sitting on your bench who can play seven positions, pinch run and is a switch-hitter, it gives you a lot of options late in the game." Porter said.

Springer gets first day off since callup

HOUSTON -- George Springer won't have to worry about following up Friday night's walk-off hit.

The rookie right fielder got Saturday off, ending a string of 15 straight starts since his mid-April callup.

"It's … just a breather," Porter said. "He's played every day since he's been here. Started thinking about it midway through the game yesterday. Sometimes, we have to protect them from themselves. And I think it's a good day for him to take a step back, relax a little bit, look at the game from a different perspective and get back in there tomorrow and be ready to go."

The touted Springer may have been pressing during his first few weeks, only hitting .180 and committing some head-scratching errors in the outfield while batting cleanup.

But the game-winner he chopped to knock off the Mariners in 11 innings may unshackle Springer from some of the burden-high expectations put on him.

"That was part of my thought process," Porter said. "I was really excited that he was able to get that game-winning hit. Obviously, it was big for the team. It was big for him. And I think it kind of just helps this whole process here of giving him a day to kind of step back and move forward from there."

Alex Presley got the start in Springer's place, with reserve Marwin Gonzalez manning the left-field spot to create a seldom-seen outfield for the Astros.
