CEDAR RAPIDS — There is no stop sign for Joel Booker.

"I’ve got a great light," the Great Falls Voyagers outfielder said. "When I get on base, I just run. That definitely feels good. I’ve always got the mindset that I’m going."

Booker has gone and gone and gone since turning professional in late June. The former Iowa Hawkeye speedster has 33 stolen bases in 48 games for two Rookie-level teams in the Chicago White Sox farm system.

Chicago’s 22nd-round draft pick this year, Booker was 26 for 27 in stolen-base attempts for the Arizona Rookie League White Sox and seven for nine since being promoted to Great Falls of the Pioneer League. His total is higher than any other player in half-season ball.

Of course, you’ve got to get on base to steal bases, and Booker has done a lot of that. He hit .296 in 33 games in the AZL and went into Saturday with a .323 average in 15 games at Great Falls.

Needless to say, it has been a great start to his career.

“Surreal,” Booker said. “I expected to play OK, but my previous experiences with wood bats, I didn’t do that great.”

Learning to swing a wood bat takes time for many guys. They’re generally heavier and have a smaller sweet spot than aluminum bats that are used in high school and college.

But Booker, 22, apparently has made the adjustment. He rebounded from a subpar junior season to hit .370 this past spring for Iowa, leading to him getting drafted.

Interestingly, he had only 23 stolen bases in 56 games this spring for the Hawkeyes.

“I shortened up my swing a lot,” Booker said. “During my college career, my swing was a lot longer. But my senior year, I worked hard to really shorten it up, and that helped a lot.”

Booker has played almost strictly center field since turning pro, but has previous experience at playing the corners, which should help him as he continues to advance in the minor leagues. Versatility is key.

The White Sox wanted him to attend their fall instructional league in Arizona, but he has elected to return to school to finish off the three classes he needs to obtain his degree in sociology. He was asked if he feels he has made a good impression on Chicago already.

“I don’t know,” he said. “I can’t worry about that. All I can do is go out and play hard. If they notice me, they notice me.”


First-year Cedar Rapids Kernels hitting coach Brian Dinkelman and his wife have decided Cedar Rapids is a pretty good place. The couple have purchased a home on the southwest wide of town and will remain here full time.

Dinkelman is a Centralia, Ill., native and played college baseball at McKendree University in Lebanon, Ill., before turning professional. He played 23 games in the major leagues with the Minnesota Twins in 2011.

Dinkelman’s sister also lives in the area, working at the University of Iowa Hospitals and Clinics.


Kernels Manager Jake Mauer said 2015 pitching coach Henry Bonilla will join the big-league Twins once his season at high-A Fort Myers is completed.


Minnesota “promotes” a pair of its minor league staff each season to observe and get a feel for the major leagues. Mauer got the opportunity last season.

Joining Bonilla in September is Gulf Coast League Twins Manager Ramon Borrego.
