Forget the rookie status. The Texas Rangers’ rookies in the rotation have pitched like savvy veterans the past two nights.

After Nick Tepesch threw 6 2/3 innings of one-run ball Thursday, Justin Grimm turned in his best start in the big leagues Friday.

Grimm threw seven scoreless innings, and the Rangers avoided a late scare to hold on for a 4-3 victory over the Twins at Target Field. Texas has won eight of its last 10 games and is the only team left in the majors without consecutive losses.

“If we keep that up for 90-95 games, we’re going to be in good shape,” shortstop Elvis Andrus said. “You’ve got to grind out every game, and we’re winning right now with good pitching and good defense.”

Grimm pitched well all night. He scattered five hits with no walks and four strikeouts, commanding his fastball well on a night his breaking ball was off and on.

Grimm, who was called up when Matt Harrison went down with a back injury earlier this month, stranded two runners in the first inning and worked out of jams the rest of the way.

The Twins’ leadoff man reached in the third, but Grimm erased that by inducing a double-play grounder in the next at-bat. The leadoff man reached again in the sixth, but Grimm retired the next three to end that threat.

Grimm pitched around a one-out single in the seventh and has not allowed a run in his last 15 innings pitched.

“I thought his performance was outstanding,” manager Ron Washington said. “He had good pop on his fastball, spotted it around the zone. He was sharp tonight.”

Grimm improved to 2-0 with a 1.59 ERA in three starts and has held opponents to 1 for 19 with runners in scoring position.

Grimm credited his success with runners on base to simplifying everything.

“I really bear down and concentrate on making that pitch to get the guy out,” Grimm said.

As far as whether it felt like his best outing in his young career, Grimm said: “From a stats standpoint, yes. From a stuff and going-at-hitters standpoint? Probably my last one.”

Either way, Grimm picked up where Tepesch left off and exited with the Rangers up 3-0.
