NEW YORK — The overhaul of the Rangers' player development staff continues.

By Tuesday afternoon, less than 24 hours after the Triple-A and Double-A seasons had ended, the Rangers had informed two managers and a handful of coaches their contracts would either not be renewed or they would be reassigned.

Triple-A Nashville manager Jason Wood, who has been in the organization for 11 years, and Double-A Frisco manager Joe Mikulik, who had been with the RoughRiders for the last five seasons, were both dismissed. Also released were Triple-A pitching coaches Brian Shouse and Eric Gagne. Hitting instructor Howard Johnson is considering a reassignment. Coach Geno Petralli will become a roving minor league instructor.

It follows only 10 days after player development director Matt Blood, who oversaw the farm system, was reassigned into a new analytical role. The club will not hire a new player development director; assistant general manager Mike Daly, to whom Blood reported as player development director, will reclaim oversight for the department.

"This is more about how we want to set things up going forward," Rangers general manager Jon Daniels said. "It wasn't about anything that did or didn't happen at Nashville. There are some things we want to accomplish going forward that will take us in a different direction."

Daniels indicated the Rangers would likely promote some internal personnel into higher profile roles in the organization. Two prime candidates would likely be Class A Down East manager Corey Ragsdale, who has also been the team's minor league field coordinator for the last four seasons, and Class A Hickory manager Matt Hagen. Both of their clubs are in their respective league playoffs.

The Rangers' affiliates finished the minor league season with the best winning percentage among all 30 MLB organizations. Of the Rangers' six U.S.-based affiliates, Nashville and Frisco were the only teams not to make the playoffs. But the focus of player development isn't necessarily wins and losses.

As the Rangers' remake their system into one that focuses more heavily on one that relies on data and technology, a changing of personnel wasn't surprising.

"Last year, there was a lot of focus on our MLB staff," Daniels said. "This time we've spent a little more time on the player development staff."

No more call-ups: With a bullpen full of young pitchers trying to get experience, there simply isn't room for the Rangers to add any more prospects in September, Daniels said Tuesday.

That is why prospects Joe Barlow and Demarcus Evans will not get looks in September. The only other call-up the Rangers will make is lefty Yohander Mendez, who can be recalled from his assignment on Thursday. Barlow, who finished the year at Triple-A Nashville, and Evans, who finished at Double-A, are expected to be added to the 40-man roster this winter.

"They have both had really good seasons," Daniels said. "But we've got enough guys up here right now that are kind of going through [an] on-boarding process that it would be hard [to find opportunities]."

Briefly: LHP Brock Burke, scheduled to pitch Friday at Baltimore, was ill Monday but reportedly much better Tuesday. ... Top pitching prospect RHP Hans Crouse, who will have offseason surgery to remove a bone spur from his right elbow, will not pitch in the Class A South Atlantic League playoffs. Crouse finished with 87 2/3 innings, a jump from 54 last year. ... Jose Trevino started at catcher for the second straight game and for the fourth time in the last five games. It's only the third time this year the Rangers have had a catcher start four times in a five-game stretch.
