Tejeda getting closer to resuming pitching

CLEVELAND -- Royals reliever Robinson Tejeda's left calf, which he pulled last Friday, is improving and he might be ready to resume pitching by this weekend against Colorado.

"He's getting better every single day, so I look in terms of him being ready, hopefully, when we get home," manager Ned Yost said.

Tejeda, who did not go on the disabled list, has allowed just one run in his last 13 2/3 innings. A streak of 12 consecutive scoreless innings ended the last time he pitched, last Thursday against Cleveland.

Greinke victim of not-so-rare double-blast

CLEVELAND -- The two home runs that one batter, Luke Scott of Baltimore, hit off Zack Greinke in one game wasn't such a rare occurrence.

TV broadcaster Joel Goldberg dug into the matter and determined that Tuesday night's double-blast was the fifth time that it's happened to Greinke in his career.

The first time came on Aug. 27, 2004, at Seattle, where the Mariners' Miguel Olivo dinged Greinke for two dingers. Odd thing, current teammate Gil Meche started that game for the M's and Olivo became Greinke's regular catcher last year in his Cy Young Award season.

The other three times came in 2005, that terrible season when Greinke lost 17 games. On June 10, Shawn Green hit two at Arizona in the memorable 12-11 Royals loss in which Greinke hit a homer, gave up 11 runs and yet had no decision. On July 30, Jonny Gomes got him twice at Tampa Bay and Jason Giambi did likewise on Aug. 28 at New York.

So Scott was the first to do it since Giambi. In a twist, Greinke could face two of those batters on Sunday, when he faces Colorado. Olivo and Giambi are now with the Rockies.

Osuna making noise at Double-A NW Arkansas

CLEVELAND -- Left-hander Edgar Osuna is attracting notice with a 4-1 record and a 1.23 ERA in eight starts for Double-A Northwest Arkansas.

Ned Yost, the Royals' new manager, got a look at Osuna recently in his previous job as a special advisor to baseball operations.

"I like him, I liked him in Spring Training," Yost said. "He doesn't light your eyes up in terms of the radar gun, but when he commands the ball on a consistent basis -- down, he's got a really nice breaking ball, a really nice change. And I've seen a lot of guys do a lot more at the big league level with a lot less than what he has."

Osuna was a Rule 5 Draft pick from the Atlanta organization at the last Winter Meetings. During Spring Training, the Royals offered him back to the Braves, who declined. So he was sent to Northwest Arkansas where he has other impressive stats: 30 strikeouts and just six walks while giving up 38 hits in 44 innings.

He doesn't throw hard.

"I go back and look at Tommy Glavine who was 90, 91 [mph] tops. Osuna was 90 tops," Yost said. "But Charlie Leibrandt was 88 with a changeup and a cutter and won 18, 20 games a year at the big league level. Changing speeds and being able to command the ball is a real effective weapon especially for a left-hander."

Yost wouldn't hazard a guess on when Osuna might surface at the Major League level but noted that he needed to develop more consistency with pitch location.

Most often a starter for the Braves, Osuna pitched in relief in the Mexican Winter League for his hometown team, Mazatlan.

"I see him more as a starter than a reliever," Yost said.

Worth noting

The Royals had the most one-run decisions in the Majors, 16, going into Wednesday night's game against the Indians.

"I don't mind a bunch of one-run games, as long as we're winning 'em," manager Ned Yost said.

The Royals were 6-10 in those games, including 1-2 in the five games that Yost had managed.
