Scott Feldman's place in the rotation isn't in jeopardy.
Feldman has lost his last four starts, posting a 6.45 ERA, but hasn't pitched as poorly as the stats suggest.
Manager Ron Washington reiterated that the Rangers have no issues with Feldman in the rotation, and his spot is secure.
"He's got to prove nothing else," Washington said. "The only thing he's got to do is do what we want them all to do and that's keep us in the ballgame. There's no issues with Feldman."
Feldman doesn't feel like he has to prove anything when he starts Saturday, either.
"That's not a good idea to start worrying about stuff you have no control over," he said. "It's tough because it's a results-oriented game. You want to win and we're on such a good team that it seems like we have a good chance to win every night. As long as I stay focused on making good pitches, all that other stuff should even out by the end of the year."
Here are a few other pregame notes:
* Rosters expand to up to 40 players Saturday, and the Rangers will have reinforcements. They will add position players and players, and will have additional players come up after their minor league seasons end. Tanner Scheppers will be recalled after Triple A Round Rock's season is over, but the team didn't reveal any other names. Brandon Snyder, Leonys Martin, Julio Borbon, Alberto Gonzalez, Martin Perez and Yoshinori Tateyama are among the players from Triple A who could be recalled, and Jurickson Profar and Justin Grimm are players in the mix from Double A Frisco.
* Mike Napoli ran straight ahead and had a good workout Friday in Cleveland. His left quad came out of it OK, and he could run the bases as early as Saturday. That's the final obstacle before Napoli is sent on a medical rehabilitation assignment, assuming the minor league seasons haven't been completed by then.
* Ron Washington said he would try and find a game to start Mike Olt in Cleveland. The Indians are scheduled to throw three right-handers, but Washington could have an everyday player serve as designated hitter in order to create a spot for Olt.
