ARLINGTON -- When Rangers starter Martin Perez takes the mound on Saturday, he'll face off against his idol, fellow Venezuelan Felix Hernandez.
"I know, for me, he is the best pitcher," Perez said. "I've seen him on television and now we're pitching on the same day. He has to do what he has to do and I have to do my job. I just want to get a win."
Perez has looked impressive this season for the Rangers. The 22-year-old left-hander is 2-0 with a 1.59 ERA over his last three starts. In his last outing on Sunday against the Astros, Perez tossed the first complete game of his big league career while allowing just one run.
Hernandez is having one of the best seasons of his career, with an AL-leading 2.28 ERA and 12-5 record. He's coming off eight scoreless innings of four-hit ball in a 2-0 win over the Brewers.
"Felix was Felix," acting manager Robby Thompson said after his ace's last outing.
But nothing usually comes easy for Hernandez in Arlington, where he'll face the Rangers again on Saturday. Hernandez is 12-18 with a 3.83 ERA in 37 career starts against Texas, including an 0-2, 4.66 mark in three starts this season.
In fact, Hernandez is tied with Chuck Finley for most losses against the Rangers by a single pitcher in the team's history. Of the 24 pitchers who have made at least 25 career starts against the Rangers, Hernandez is among four who have a losing record against them despite having a sub 4.00 ERA. Nolan Ryan, Dennis Eckersley and Moose Haas are the others.
He has the second most losses against one team among active pitchers. Mark Buehrle has lost 19 times to the Twins and 17 times to the Indians.
Hernandez dropped a 5-2 decision to the Rangers on May 25, but has gone 7-1 with a 2.10 ERA in 14 starts since. Hernandez had an even hotter stretch in midseason last year when he went 9-0 with a 1.40 ERA over 14 starts from June 17-Aug. 27, including his perfect game on Aug. 15.
The 27-year-old said he feels much like he did last year at this time.
"Yeah, I feel pretty good," he said. "Some days I don't have my best stuff, but it feels pretty similar."
Mariners: Franklin's struggles at the plate continue
After a torrid start to his rookie campaign, second baseman Nick Franklin is hitting below .200 in July and August. Prior to that stretch, Franklin was hitting .295 over 31 games. His 10 home runs rank fourth among American League rookies.
"When young guys get up here, you're going to be tested to see if you can hit a fastball," said Thompson. "If you can't, you're going to keep getting them. Well, he's a pretty good fastball hitter. Now all of the sudden, word gets out and they're throwing breaking balls in fastball counts and he has not really made that adjustment yet. That should come with time."
Rangers: Ogando may not start against Astros
The inflammation in pitcher Alexi Ogando's right shoulder's hasn't subsided and may prevent him from making his scheduled start on Monday against the Astros. Ogando is seeking a second opinion from Dr. James Andrews after receiving a CAT scan from Dr. Keith Meister on Wednesday.
Ogando has already been on the disabled list twice this season. He was sidelined from May 16 to June 5 with triceps tendinitis and, after making just one start, again from June 6 to July 23 with inflammation in the shoulder. This time the inflammation is affecting a different area.
If Ogando is unable to make his start, the duty may fall to long-reliever Ross Wolf, who has pitched only one inning since July 28. He is 1-2 with a 6.89 ERA in three spot starts.
• Brad Miller has already hit five triples in 42 games to rank fifth in the American League and lead all AL rookies.
• Third baseman Kyle Seager has a career .374 (34-for-91) batting average at Rangers Ballpark.
• The Rangers have won eight of their last 12 contests with the Mariners.
