Rangers on impressive run in August

ARLINGTON -- The Rangers went into Tuesday's game with 107 runs scored in August, the most in the American League by 17 over the Red Sox. The Rangers were averaging 6.3 runs per game, and with 10 games to go in the month, were on pace to score 170 runs in the momth. Their record for most runs in any month was 185 in August, 1977.

The Rangers were eighth in runs scored in July and 12th in June. The improvement this month has come depsite Nelson Cruz serving his 50-game suspension, although the Rangers were able to alleviate that loss by acquiring Alex Rios from the White Sox.

"We have been able to get loose on the basepaths," manager Ron Washington said. "We have been able to do a lot of things that have been presented to us. If Nelson had been in the lineup, it would have been the same thing."

Astros manager Bo Porter has seen the Rangers wreak havoc on his pitching.

"They're using their skill sets to put them in the best position to be successful," Porter said. "There's no weak links up and down their lineup."

Shoulder lands Ogando back on disabled list

ARLINGTON -- Rangers pitcher Alexi Ogando is back on the disabled list with inflammation around a nerve in his right shoulder. The Rangers determined Ogando will miss more than one start and placed him on the DL on Tuesday to make room for pitcher Travis Blackley.

"It's nerve irritation that's been treated with an injection and oral medication," Rangers general manager Jon Daniels said. "He has had some response, but not enough to be ready to throw. If it was one start, we might play with the roster, but it will be a minimum of two starts, so we felt, let's get it knocked out and see where it is. That basically gets us to September."

Ogando last pitched on Aug. 13, so he is eligible to come off the disabled list on Aug. 29. Blackley started on Tuesday night against the Astros and is scheduled to pitch again on Monday against the Mariners. Blackley's spot in the rotation would come up again on Sept. 1, and the Rangers are hoping Ogando could be ready by then.

This is the third time Ogando has been on the disabled list this season and the second time because of a shoulder problem. He was sidelined from May 16 to June 5 because of biceps tendinitis and June 6 to July 23 with shoulder inflammation. The Rangers don't believe the injuries are related.

"Of course, I'm disappointed," Ogando said. "Nobody wants to be on the disabled list. You want to compete and help the team."

Blackley was called up from Triple A Round Rock after being acquired from the Astros last week. Daniels acknowledged the Rangers have looked for a more established starter on the trade market, but nothing has materialized. Erik Bedard of the Astros and Dan Haren of the Nationals are among the pitchers that have reportedly cleared waivers.

"I am comfortable with what we've got," Daniels said. "You are always looking around, but I don't anticipate anything. A few guys have cleared waivers, but I'm not sure about the guys that are available and that we're interested in are at the right price. We like our team."

Feliz will be reliever upon September return

ARLINGTON -- General manager Jon Daniels said the Rangers will have more discussions in the offseason about the future roles of pitchers Neftali Feliz and Alexi Ogando. For now, Ogando will be used as a starter when he comes off the disabled list and Feliz will be used as a reliever when he returns in September.

Ogando was a reliever in 2010 and '12, and a starter in 2011 and this season. Feliz was the Rangers' closer in 2010-11 before moving into the rotation last season. Feliz made seven starts before elbow problems led to Tommy John elbow reconstruction surgery on Aug. 1, 2012. He has made five appearances on a rehab assignment, including a scoreless inning with two strikeouts for Triple A Round Rock on Monday.

"He's getting a little better each time out and his velocity is picking up," Daniels said. "He's taking it step by step to make sure he's 100 percent."

As far as Feliz's future role, Daniels said, "We haven't had a conversation about that recently. If we made the decision today, it would probably be in the bullpen. We don't have to make it now."

The Rangers are taking the same approach with Ogando's future as they try to determine if the increased workload as a starter has led to the injuries this season.

"I don't know if anybody really knows," Daniels said. "That's a topic of conversation, if he's better going to the bullpen. But that's probably a topic of conversation for next year. Right now, we have limited options with our starting rotation."

Ogando said he does not believe his injuries are related to moving back into the rotation, and made it clear what he wants to do in the future.

"Start," Ogando said.

Intentional walks don't bother Pierzynski

ARLINGTON -- The Astros made the choice to intentionally walk Adrian Beltre twice in Monday's game and take their chances with A.J. Pierzynski. After the first walk, Pierzynski struck out. The next time, in the third inning, Pierzynski delivered a two-run single. It was the first of his four hits on the night.

"Adrian is one of best hitters in baseball," Pierzynski said. "You can't blame them. You want to make them pay, but you don't try to change anything. You almost have to try and calm down."

Beltre has been intentionally walked eight times this season. That's nothing for Pierzynski, who spent one season with the Giants in 2004. That was the year Barry Bonds was walked a record 232 times, including 120 intentionally, as the Giants' cleanup hitter. Pierzynski hit fifth and sixth in the order and had a career high 77 RBIs.

"There were a lot of guys on base in front of me," Pierzynski said. "[Bonds was] the best hitter I've ever seen and nobody comes close. He'd get one hit to pitch in three games and he would hit a home run. It was amazing."

Worth noting

• Washington said Leonys Martin and Elvis Andrus took it upon themselves to pull off a first-inning hit-and-run on Monday. Martin broke on a 1-1 pitch and Andrus singled through the right side, moving Martin to third. Said Washington, "I love the hit-and-run, but when I put it on, they don't execute it. If they put it on themselves, it works."

• Andrus is one of five active players with three steals of home in their careers. The others are Torii Hunter, Alex Rodriguez, Juan Pierre and B.J. Upton.

• The Rangers have promoted infielder Alejandro Selen from Class A Hickory to Double-A Frisco.

• The Rangers recalled pitcher Matt West and put him on the 60-day disabled list. The move was made to make room on the 40-man roster for pitcher Travis Blackley. West is still recovering from Tommy John elbow reconstruction surgery.
