Rangers could trade lefty Cotts, or re-sign him

ARLINGTON -- The Rangers continue to field trade calls on relief pitcher Neal Cotts, but there were no indications that something would get done before the 3 p.m. CT Thursday non-waiver Trade Deadline.

Another option could be preferable to the Rangers. They are considering the possibility of re-signing Cotts, who could be a free agent after the season.

"That wouldn't be bad," Cotts said. "Not at all, with the people we have coming back. We have had quite a few injuries and we have underplayed somewhat, but I think it will be a different situation next year. We're going to have a good ballclub."

If so, the Rangers could use a left-hander reliever who entered play Tuesday with five consecutive scoreless outings and had a 2.19 ERA in his last 39 outings. He came into the game against the Yankees 2-5 with a 3.20 ERA.

Right now, most of the Rangers' trade discussions have revolved around Cotts and outfielder Alex Rios. The Rangers have an option on Rios for $12.5 million for next season, so they aren't interested in just giving him away. The Rangers are likely to finish the season under budget after trading Joakim Soria to the Tigers last week. As with Cotts, the Rangers expect a reasonable return on Rios, and they would strongly consider the possibility of bringing him back in 2015.

Wash: Martin getting better, but more needed

ARLINGTON -- Rangers outfielder Leonys Martin went into Tuesday's game hitless in his last 16 at-bats over the previous five games. He also was hitting .200 in his last 22 games.

At a time when the Rangers want to see progress from their young players, they are not seeing as much as they would like from Martin, 26, who is in his second full season in the Major Leagues.

Manager Ron Washington said Martin, a left-handed hitter, is back in the habit of trying to pull everything rather than using the entire field.

"He's got to use the whole field, he can't just use one part of the field," Washington said. "If you look at the numbers, most of his hits are two steps to the shortstop side of second base around to [first base]. He's got to do something different. You call that adjusting. He's got to make an adjustment."

According to STATS Inc., Martin goes to the right side or right field 51 percent of the time against right-handers, up the middle or center field 37 percent of the time and just 13 percent to the opposite way. Against left-handers, Martin pulls 42 percent of the time, goes up the middle 37 percent and the opposite way just 22 percent of the time.

"Martin has got to make an adjustment," Washington said. "He needs to find that consistency by making adjustments. You constantly have to adjust. He is getting better. The increments are not as big as you would like, but he is getting better."

Rangers reshuffle rotation with Tepesch sidelined

ARLINGTON -- Rangers starter Nick Tepesch is still not completely over the problem in his left knee, and thre Rangers have pushed him back in the rotation. He was supposed to start on Friday against the Indians, but the Rangers are going to start Jerome Williams instead, followed by Miles Mikolas on Saturday and Yu Darvish on Sunday.

Tepesch last started on Saturday against the Athletics, but he had to come out of the game in the seventh inning because discomfort in the left knee. The Rangers still don't think the injury is serious, and they are not planning to put Tepesch on the disabled list.

"He took himself out of his last start, so we're not going to rush him back," manager Ron Washington said. "He'll miss one turn and be back."

Tepesch played catch on Wednesday and is hoping to have a bullpen session on Friday.

"I would say [the knee] is close, but I wouldn't say it is 100 percent," Tepesch said.

Williams, called up from Triple-A Round Rock, started against the Athletics on Friday and allowed one run in six innings. The Rangers originally considered pitching Darvish on Saturday on his normal four days' rest. But with the Rangers off on Thursday, they are going to use that to give all of their starters extra rest.

Worth noting

• Darvish earned his 10th win on Monday night. He is the first Rangers pitcher to win at least 10 games in each of his first three seasons in the Majors.

• Double-A Frisco pitching coach Jeff Andrews will be working this fall. He will be the pitching coach at Surprise in the Arizona Fall League.

• Third baseman Adrian Beltre's double on Monday night was the 517th of his career, tying him with Scott Rolen for 48th all-time.
