BALTIMORE -- Two former top pitching prospects are trying to get their careers revived in the lower levels of the Rangers' farm system after major injuries ruined their 2013 season. David Perez is off to a better start than Kevin Matthews.

Perez, who is still just 21 and missed most of the past two seasons because of Tommy John surgery, has not allowed a run in his first four appearances for Class A Spokane in the Northwest League. In five innings he has allowed one hit and four walks while striking out three.

Matthews was the Rangers' first-round pick (33rd overall) in the 2011 First-Year Player Draft who missed all of last season because of surgery on his left shoulder. He is currently with the Arizona Rookie League Rangers and in three appearances he has allowed nine runs on 11 hits and five walks. Like Perez, Matthews is just 21 years old after being drafted out of high school.

Matthews and University of Georgia outfielder Zach Cone were the Rangers' compensation picks in the 2011 draft for losing free agent pitcher Cliff Lee to the Phillies. Cone, whose career has also been set back by a major injury, is hitting .191 at Spokane.

Rios moved up to No. 3 spot in lineup

TEX@OAK: Rios hits a long sac fly to left field

BALTIMORE -- Alex Rios was moved up to the No. 3 spot in the lineup on Tuesday with left-hander T.J. McFarland on the mound for the Orioles.

Rios is one of the few Rangers hitters who have had success in the No. 3 spot this season. For the most part, it has been the biggest trouble spot in a lineup that had Robinson Chirinos batting fifth, Chris Gimenez batting sixth and Adam Rosales in the seventh spot at designated hitter on Tuesday night.

For the season, Rangers No. 3 hitters are batting a combined .213 with a .266 on-base percentage and a .315 slugging percentage going into Tuesday's game with the Orioles. All three figures are the lowest in the Majors for that spot in the lineup. Rios is hitting .305 in his 14 games as the No. 3 hitter. For most of the season he has been batting fifth.

"I'll do what I have to do," Rios said. "I have hit in that spot before. I don't think anything is different, you just have to be aware of the situation."

The .213 batting average and the .266 on-base percentage are currently the lowest ever for the Rangers' No. 3 hitters in a single season. The slugging percentage is the second lowest behind the 1973 Rangers with a .311 figure.

The lowest collective batting average for a team's No. 3 hitters was .205 by the Houston Colt 45's in 1963. The lowest on-base percentage is .261 by the 1982 Padres.

The Rangers have the fourth lowest batting average and the second lowest on-base percentage. The slugging percentage is the 17th lowest all-time. Rangers manager Ron Washington has been scrambling to a find a No. 3 hitter ever since Prince Fielder was lost for the season because of neck surgery.

"I can only pick from what I have," Washington said. "I'm no different than anybody else. I would love to have a No. 3 hitter. But this is the year things didn't go as planned. My No. 3 hitter is on the disabled list."

Beltre named Rangers Player of the Month

MIN@TEX: Beltre hits RBI single, escapes rundown

BALTIMORE -- Adrian Beltre, who is currently running second in the All-Star voting among American League third basemen, picked up a few extra votes on Tuesday. It won't help him in the All-Star voting, which ends Thursday, but he was selected as the Rangers Player of the Month for June.

It was the sixth time since August 2012 that he has won the award. Beltre finished the month hitting .392, second highest in the American League and fifth highest for June in Rangers history. He was also tied for third in the A.L. with 22 RBIs. It was the highest batting average for any month in his career.

"It was progress from the month before," Beltre said. "I was more consistent and produced a little better. Hopefully I will have a better month this month."

In the latest All-Star voting update released Monday, Beltre has 1,730,748 votes while Josh Donaldson has 2,943,332 votes to be the starting third baseman for the American League in the All-Star Game. Beltre still could be elected as a reserve by the players when the teams are announced on Sunday.

"I don't think anybody is thinking about that right now," Beltre said. "It's one of those things, been there, done that. Those three or four days could come in handy in getting some rest."

Rangers limited in international signings

Rangers GM Daniels breaks down reasons for Ortiz pick

BALTIMORE -- The international amateur signing period begins on Wednesday. The Rangers won't make a big splash, but they are still trying to sign talent out of Latin America.

The Rangers are limited to what they can spend because they exceeded last year's limits in signing pitcher Marcos Diplan, infielder Yeyson Yrizarri and outfielder Jose Almonte among others. It was considered an excellent haul but also limits them this time around.

The Rangers are limited to approximately $2 million in spending but can not spend more than $250,000 on any one player.

"We were aware when we did what we did last year that we would have limits," Rangers assistant general manager Thad Levine said. "We planned for that so we challenged our scouts to find players with different price points. We are encouraged by what they have done. They have put us in position to sign some attractive players."

Worth noting

• Gimenez started at first base on Tuesday for the first time this season and Rosales was used at designated hitter. It was only the third time in his career that Rosales started a game at designated hitter. The Orioles had left-hander T.J. McFarland on the mound and Washington was trying to get as many right-handed hitters as he could in the lineup.

• Chirinos was in the fifth spot in the lineup for the first time on Tuesday. Chirinos was hitting .314 in his last 20 games prior to Tuesday.

Derek Holland is not on the road trip. Holland, who is still recovering from offseason surgery on his left knee, remains in Arlington working out and strengthening his left knee. He still hasn't passed the fielding tests needed to go on a medical rehabilitation assignment and there are no plans to have him go through another simulated game until the Rangers return from the road trip.
