Notes: Feldman's knee, Ogando's workload

ARLINGTON, Texas -- Rangers starter Alexi Ogando has pitched 59 2/3 innings so far this season, the third-most of any starter. Ogando pitched 72 1/3 innings in Frisco, Oklahoma City and Texas all of last year as a reliever (he did make three starts in Frisco).

Manager Ron Washington said he's not concerned about the workload and believes Ogando can handle it. It helps that Ogando is 27 years old and Washington notes that Ogando is in excellent shape. He's getting an extra day of rest before his next start thanks to Thursday's off day, but the club has no plans at this point to try to scale him back.

"I think Ogando has shown you that his stamina is as good as any pitcher in the game of baseball," Washington said. "Each time he's been out there late in the ball game, he's still popping 95, 96 [miles per hour]. That tells you right there he's not losing stamina.

"He might not have had that many innings on his arm, but you know in this game there's always waters that are being chartered that people have never been through before."

As for the blister that caused the team to skip one of Ogando's starts earlier this season, the hurler hasn't had any issues his last two outings. That's a good sign.

"After 80 to 85 pitches, we go check on it and see how it's feeling every inning," Washington said. "Last time, it looked the same then as it did when the game started."

Rangers president and CEO Nolan Ryan talked to Ogando about the maintaining the blister and how to deal with it and Washington in convinced that's helping.

Other notes:

* Scott Feldman said Wednesday that he has experienced some weakness in his right knee in the latter innings of his starts, which he believes is causing his velocity to drop.

He's going to talk with the medical staff and determine where he goes from here. He's been pleased with the arm strength, but wants to see what he can do about strengthen the knee. He had microfracture surgery on the knee on Nov. 3, 2010.

* Mark Lowe has pitched well since his return from the minors, getting more movement on his slider and controlling his fastball better. "We got him to be a guy that pitches in winning situations."

We'll have more on Lowe tomorrow morning on the blog.
