Tuesday in the Royals farm system

This is a look at what’s happening with teams in the Royals minor-league system.

Class AA Northwest Arkansas lost a wild one on Tuesday night in Texas.

The Naturals scored seven in the top of the second inning, then gave up 14 runs and lost 14-7 at Frisco.

Whit Merrifield hit a three-run homer and Matt Fields had a grand slam as Northwest Arkansas jumped ahead 7-0.

Frisco scored four in its half of the second, then pushed five more runs across in the third. Those runs all came against Jason Adam, who was a fifth-round pick in the 2010 draft out of Blue Valley Northwest.

Adam allowed 10 hits and nine earned runs in 2 2/3 innings, while walking two and striking out four.

Frisco added a run in the fourth against Santiago Garrido, then scored four times in the sixth against Sam Runion. The RoughRiders pounded out 18 hits and drew five walks.

The Naturals had just five hits, but walked six times. Frisco starter Cody Buckel’s line: 1 2/3 innings, 1 hit, 6 runs, 0 earned runs, 5 walks, 3 strikeouts.

Elsewhere on Tuesday:

Class AAA Omaha

The Storm Chasers wasted a strong effort by lefty Will Smith and lost 3-1 in 10 innings to the Albuquerque Isotopes in Omaha.

Smith threw six shutout innings, striking out eight. Omaha scored its only run in the second inning, thanks to an Isotopes error.

It was 1-0 in the eighth inning when Alex Castellanos hit a two-out homer off Dan Wheeler to tie the game.

In the 10th inning, the Isotopes had four straight two-out hits against Louis Coleman and scored two runs.

Class A Advanced Wilmington

Wilmington rallied to beat Carolina 4-3 in Delaware.

Carolina was up 3-2 going to the bottom of the sixth when Lane Adams singled with one out. Daniel Mateo followed with an RBI triple, and he scored on a groundout by Kenny Diekroeger as the Blue Rocks took a 4-3 lead.

The Mudcats put runners on second and third with one out in the eighth, but Robinson Yambati got a strikeout and a groundout to end the threat. Carolina had a runner at third with one out in the ninth, but Yambati struck out the last two batters of the game.

Yambati, 22, is a 6-foot-3, 208-pound right-hander out of the Dominican Republic. Baseball America’s Prospect Handbook lists him as the 28th-ranked prospect in the Royals’ system.

Adams, Mateo and Jorge Bonifacio all had two hits.

Class A Lexington

The Legends were held to three hits in a 2-1 loss at Augusta.

Shortstop Raul Mondesi, catcher Cameron Gallagher and right fielder Ethan Chapman each had a single for Lexington.

Right-hander Bryan Brickhouse gave up six hits and two runs while striking out five in six innings. However, his record dropped to 0-3.
