Royals' Chen strikes out 11 in Triple-A rehab start

DETROIT -- Left-hander Bruce Chen set out to prove he was ready to return to the Royals, and he may have done so Wednesday in a rehab start for Triple-A Omaha.

Chen struck out 11 batters and walked just one in 5 1/3 innings against Albuquerque. He gave up two earned runs and three hits while throwing 87 pitches (56 strikes).

The Royals lack a long man in the bullpen, and that could be Chen's role. He began this season as a starter but went on the disabled list on May 2 with a bulging disc in his back. He has since been successfully succeeded in the rotation by lefty Danny Duffy.

In his four starts for the Royals, Chen was 1-2 with a 7.45 ERA.

Henry's one-hitter in 1983 stands test of time

DETROIT -- Doug Henry, the Royals' bullpen coach, got a new round of texts when a one-hitter was thrown during the weekend at the College World Series in Omaha.

Henry, then a freshman at Arizona State, threw a one-hitter in the 1983 tournament to beat Maine, 7-0. So his name surfaced again.

"The hit came in the third or fourth inning," Henry said of his experience. "It was hit hard, but it was a ball that Hoz [Eric Hosmer] would have picked really easily -- but it got by our first baseman; it went under his glove.

"I didn't think anything of it -- it was smoked. But about the seventh inning [Jim] Brock, our head coach, started going to the umpire saying, 'Hey, this guy's in the middle of what should be a no-hitter -- that should've been an error.'"

In the small world department, Henry's catcher in that game was Don Wakamatsu, now the Royals' bench coach.

"I went deep in that game," Wakamatsu said, grinning.

Barry Bonds was also on that team.

At any rate, the official scorer did not change the ruling.

"After the game, they said that [Brock] was still trying to get it changed," Henry said. "But I said, 'It's too late now. I'm good with what happened, we won the game.'

"But after the game the coach of Maine, who was the coach of the USA team for the Pan American Games, invited me to come and be a member of the USA team because a couple of their pitchers got drafted, and they had some spots open. So that got me around the world that summer -- it was awesome; it was a great experience."

This year's one-hitter, by Virginia's Nathan Kirby and Artie Lewicki, was the first since 1983, but, oddly, Henry's gem was not the most recent. Later in the '83 tourney, two Alabama pitchers teamed up for a one-hitter to beat Arizona State, bumping the Sun Devils out of the tournament.

"Every once in a while I get texts from friends saying, 'Hey I was watching the College World Series and they mentioned your name,' so that's pretty cool," Henry said.

Royals prospect Dozier advances to Double-A

DETROIT -- Third baseman Hunter Dozier, the Royals' first-round selection in the 2013 First-Year Player Draft, has been promoted to Double-A Northwest Arkansas.

Dozier, rated the Royals' No. 6 prospect by MLB.com, batted .295 (66-for-224) for Class A Advanced Wilmington this year with 18 doubles, four homers, 39 RBIs and a .397 on-base percentage.

In 2013, Dozier's first professional season, he hit .303 for the Rookie team at Idaho Falls and then .327 for Class A Lexington. He had seven home runs, 30 doubles and 52 RBIs in a combined 69 games for those two teams.

Crown points

• Right fielder Nori Aoki was not in the Royals' starting lineup on Wednesday against the Tigers even though he was recovered from Tuesday night's leg cramp. He was held out as a precaution, with Lorenzo Cain starting in right field and Jarrod Dyson in center.

• Third baseman Danny Valencia had a home run, a single and a walk in his first injury rehab appearance for Triple-A Omaha as the Storm Chasers beat Albuquerque, 13-6. He's coming back from a left hand strain.
