Wash gives his take on the A's

ARLINGTON -- The Oakland A's had the highest winning percentage of all 30 MLB teams in the league and held down a 63-38 record Friday entering their game with the Rangers.

The Rangers on the other hand, were 40-62 before the game, with the lowest winning percentage in the league.

Rangers manager Ron Washington took a few minutes to address the success Oakland has enjoyed. The teams battled it out for the American League West the last two seasons.

"Those guys that they've got in that lineup are performing. They have a very functional lineup, they have tremendous starting pitching and ... they've got a solid bullpen," Washington said. "They seem to be able to fill their holes when holes present themselves and they play very well together. Right now, they believe in themselves."

Washington maintains that before his team fell victim to so many injuries, it could've competed at that level.

"I have no doubt about it. My team in Spring Training, if we stayed healthy and the guys that we depend on do what they're supposed to do, we would've been there competing," Washington said. "I still believe that."

In the middle of all the injuries and the hefty load of adversity the Rangers have been forced to face, Washington has kept the same, consistent approach.

"Just keep trying to play good baseball. That's all," Washington said. "Once again, it just comes down to taking advantage of the opportunities that we present -- that we create, really. We haven't been able to."

Smolinski makes latest trip to DL

ARLINGTON -- To make room for right-handed pitcher Jerome Williams, who started Friday against the A's, the Rangers moved outfielder Jake Smolinski to the 15-day disabled list retroactive to July 22. To make room on the 40-man roster, the Rangers released right-handed pitcher Justin Marks.

Smolinski fouled a pitch off of his left foot Monday against the Yankees. X-rays were negative, but Rangers manager Ron Washington said that with Smolinski being a rookie, the Rangers didn't want to push it.

"Life in baseball. Tough break, too," Washington said. "He still has some discomfort and we want to make sure it's right."

In placing Smolinski on the disabled list Friday, the Rangers have now used the disabled list 23 times, which leads the Majors. They used it 25 times in 2010 and the club record is 29 in 2004. Only seven players -- Elvis Andrus, Robinson Chirinos, Shin-Soo Choo, Neal Cotts, Leonys Martin, Alex Rios and Shawn Tolleson -- have been on the active roster for the whole year.

Washington hopes Smolinski's stint on the list is a brief one.

"Just go back on the disabled list and track the days that it went back to and we're looking at maybe 10 days, 11 days," Washington said. "Give him a chance to heal 100 percent."

Worth noting

• Of the 14 players on the Rangers disabled list, nine of them are on the 60-day.

• The Rangers were a season-high 23 1/2 games behind the A's, who lead the division, entering Friday's game. The last time the Rangers' deficit was that large was in 2003, when they finished the season 25 games behind the A's, who won the division that year.

• The Rangers had dropped eight straight and 22 of the past 30 games at home entering Friday.
