ARLINGTON -- Catcher Jarrod Saltalamacchia passed a number of tests on his upper back and left shoulder on Friday.

Saltalamacchia, who was placed on the disabled list Thursday, had an X-ray, MRI and nerve test done and the results all came back normal. Dr. Drew Dossett gave Saltalamacchia an anti-inflammatory injection that will likely take a couple of days to take effect.

Saltalamacchia injured himself during Monday's game with the Blue Jays.

Rangers hold hitters meeting

ARLINGTON -- The Rangers, batting .168 in their first three games, had a hitters meeting before Friday's game with the Mariners.

First baseman Chris Davis had the details.

"We pushed the panic button, pulled the fire alarm and turned on the sprinklers," Davis said.

He was joking. But the Rangers know their offensive performance in the opening series against the Blue Jays was not what they expected.

"We have not had good at-bats," Michael Young said. "That's something that's going to change. We're a confident group and we know it will it change. Sometimes when you get in a slump, you have to ride it out, and sometimes there are specific things you have to work on. Sometimes you need it simple and just be aggressive at swinging at pitches in the strike zone."

The hitters meeting was routine. The Rangers have a hitters meeting before every series to go over the opposing pitchers.

"We talked like we do all season long," Young said. "We talked about how we can get better. We'll do that the whole season."

Rangers plan to stick with Borbon

ARLINGTON -- Manager Ron Washington isn't ready to shake up the lineup. Julio Borbon was back in the leadoff spot on Friday, even though he went 0-for-12 in the first three games. He was 0-for-8 against left-handers, and the Mariners had a left-hander on the mound Friday.

But Washington is sticking with Borbon as his center fielder.

"He doesn't need a day off," Washington said. "He's 22, 23 years old. We believe in Borbon. We're going to let him work through this. He'll be fine. I'm not saying I won't give him a day off, but he's not ready yet.

"There is nothing wrong with Borbon. It's a matter of finding holes. Once he finds the holes, it will start coming in bunches. It's just a matter of things falling for him. He's not in a panic mode and we're not in a panic mode."

Going into Friday night, the Rangers were the only American League team without a hit from their center fielder.

Arias, Blanco sharing time at second

ARLINGTON -- The Rangers played their fourth game on Friday night and Joaquin Arias made his second start at second base. So far, manager Ron Washington has been alternating Arias and Andres Blanco at second while Ian Kinsler has been sidelined with a sprained right ankle.

Washington said Blanco will likely start at second on Saturday afternoon.

"I'm getting them both at-bats," Washington said. "It's not like one has jumped out in front of the other. I just know Blanco can play shortstop, but I'm just trying to give them both opportunities."

Washington also said Matt Treanor will likely get his first start at catcher on Sunday. Treanor, acquired from the Brewers three weeks ago, was called up on Thursday when the Rangers put catcher Jarrod Saltalamacchia on the disabled list with stiffness in his upper back and left shoulder.

"Obviously, this is not the way the club wanted to see me get up here," Treanor said. "For me, it's an opportunity to make sure there is a smooth transition and no disruption behind the plate."

Washington likes Guerrero on the bases

ARLINGTON -- Vladimir Guerrero got thrown out on the basepaths in a key situation on Thursday afternoon. With two outs and Michael Young on first, Guerrero lined a single to left-center. Young went to third, so did the throw and Guerrero tried to take second on the play.

He was thrown out, but manager Ron Washington said Guerrero's only fault was not going full-out coming out of the batter's box.

"He didn't make his mind up until after he had stopped his momentum," Washington said. "If he hadn't done that, everybody would be cheering."

But Washington likes Guerrero's aggressiveness on the basepaths. In the fourth inning, Guerrero reached on a single, then dashed to second on a wild pitch that bounced in the dirt but stayed in front of catcher Jose Molina. The ball didn't get far away, but Guerrero made it to second easily.

"We've got guys who are way more speedy than him, but that's his instincts right there," Washington said. "I'm happy that's part of his game. I want it to be a part of all our [players'] game."

Worth noting

ARLINGTON -- Vladimir Guerrero is only the fifth player in the last 100 years to have at least 2,000 hits in his career and at least seven hits in his first three games with his new team. The others were Manny Ramirez (2008, Dodgers), Willie Wilson (1993, Cubs), Al Oliver (1984, Phillies) and Leon Goslin (1934, Tigers). ... Guerrero went into Friday's game hitting .407 in 53 career games at the Ballpark in Arlington. Going back to 1952, no other player finished with -- or currently has -- a .400 batting average in any of the current 30 ballparks with a minimum of 50 games played there. ... Blake Beavan, the Rangers' No. 1 Draft pick in 2007, made his first start for Double-A Frisco on Thursday night and allowed one run in six innings in a 2-1 victory over Springfield.
