Dyson returns to Kansas City after going on disabled list

Outfielder Jarrod Dyson is expected to miss two-to-four weeks after being diagnosed Friday in Kansas City with what trainer Nick Kenney termed “a mild high ankle sprain.”

Dyson, 28, suffered the injury in the eighth inning Wednesday when he scaled the center-field wall at Angel Stadium in pursuit of a Mike Trout homer against Kelvin Herrera.

Kenney said the injury occurred as Dyson tried to propel himself up the wall when his cleats gripped the padding. Dyson returned early Friday to Kansas City to undergo further tests.

The Royals learned of the results just prior their series opener Friday against the A’s at the Oakland Coliseum. The club replaced Dyson by recalling outfielder David Lough from Class AAA Omaha.

Lough, 27, started in right field Friday and batted leadoff. He arrives after batting .340 with a .393 on-base percentage in 36 games for the Storm Chasers. He batted .237 last season in 20 big-league games.

Dyson’s injury came just as he was starting to gain regular playing time. He started five of the last eight games and was batting .268 with eight extra-base hits in 41 at-bats.

The injury is also the first since the season started that required the Royals to place a player on the disabled list. The move is retroactive to Thursday, which means Dyson is eligible to return for the May 31 game at Texas.

French bacon

Right fielder Jeff Francoeur made a pre-game trip to the parking lot to meet with the “Bacon Tuesday” fans who populate the right-field seats at the Oakland Coliseum.

“Said hi to them,” he said. “Got some pictures with them. Got my T-shirt.”

Francoeur is a group favorite. And why not? He loves bacon, too.

On previous trips, he flipped a baseball into the group with a $100 bill with the suggestion to buy bacon and beer. He purchased 20 pizzas and had them delivered on another occasion.

A’s moves

The A’s summoned reliever Hideki Okajima from Class AAA Sacramento prior to Friday’s game after clearing space by designating struggling right-hander Chris Resop for assignment.

Okajima, 37, made 261 appearances for the Red Sox from 207-11. He compiled a 2.16 ERA in 16 ⅔ innings at Sacramento. Resop allowed 12 runs and 22 hits in 18 innings.

The A’s also announced right-hander Brett Anderson suffered a setback in his comeback — a stress fracture in his right foot that will likely sideline him for two months. He suffered a sprained ankle in late April.

Minor details

Class AAA Omaha reliever Blaine Boyer exercised an out clause in his contract and became a free agent. He was 0-1 with a 3.00 ERA in 13 appearances for the Storm Chasers.

Boyer sought the release to pursue an opportunity with a Japanese club

The Royals signed Boyer, 31, to a minor-league deal on Jan. 3 in his comeback bid after not pitching last season. He was 9-14 with a 4.81 ERA in 233 games with four big-league clubs from 2005-11.

Minor citation

Class AA Northwest Arkansas right-hander Yordano Ventura drew a citation again in

Baseball America’s Prospect Hot Sheet

, which seeks to identify which of the game’s top prospects are performing the best.

Ventura, 21, suffered his first loss of the season Thursday despite holding Arkansas to two runs and three hits in six innings. He is 3-1 with a 1.79 ERA in eight starts. He also has 56 strikeouts in 40 ⅓ innings.

“Some of Ventura’s numbers a getting downright silly for the Double-A level,”

Baseball America

reported. “(He) had a 16-inning shutout streak snapped Thursday, but he still hasn’t allowed more than two earned runs in any of his eight starts.”

International rumors

Outfielder Cristhian Vasquez, a 16-year-old Venezuelan, is drawing interest from the Royals, according to

Baseball America.

A left-hander, he is 5 feet 11 and 180 pounds.

The international signing date is July 2 for players who are at least 16 years old and not eligible for baseball’s draft. That typically includes all players from Latin America outside of Puerto Rico.

The magazine’s website praises Vasquez’s “sweet swing,” which it said comes with “gap power” but labels him as “an average runner who will have to play left field because of his lack of arm strength.”

Baseball America

likened Vasquez to Yankees prospect Ramon Flores, who signed in 2008 for $800,000. It believes Vasquez will seek a similar deal.

Looking back

It was 37 years ago Saturday — May 18, 1976 — that the Royals beat Texas 3-1 and moved into first place in the American League West Division.

Amos Otis keyed the attack with a homer against Texas starter Jim Umbarger, and Al Fitzmorris improved to 5-0 by pitching a complete game.

The Royals would remain atop the division for the rest of the season en route to the first of their six division titles in 10 years.
