Don’t send Sherlock Holmes to Albuquerque quite yet to determine if there’s any mystery surrounding the performances of pitchers Rex Brothers and Jon Gray.

Brothers and Gray, whom many thought would be on the Rockies’ roster to start the season, are struggling in the early going of the Triple-A Pacific Coast League season. But Zack Wilson, the Rockies’ director of player development, said there isn’t any mystery as to why.

“We look at Brothers as an elite pitcher and we look at Gray as a player who will become an elite pitcher,” Wilson said. “They both are working on some things to get better.”

While Wilson contends their showings so far reflect normal ups and downs, the Rockies could use help from Triple-A to bolster a sagging pitching staff.

Brothers, who had 19 saves with the Rockies in 2013 before faltering last year and being sent to Triple-A during spring training this year, is searching for control. The left-hander surrendered six walks and allowed four earned runs over five innings in his first five appearances.

Gray, a 6-foot-4 right-hander who was a candidate to be in the Rockies’ rotation before tailing off at the end of spring training, has had first-inning problems.

In three appearances, Gray is 0-2 with a 9.00 ERA. Of the 14 earned runs he has allowed, 11 have been scored in his first inning of work.

Trading places. The Rockies’ farm system has a new look. Al- buquerque has replaced Colorado Springs as the Triple-A affiliate. The Double-A team has moved from Tulsa, Okla., in the Texas League to New Britain, Conn., in the Eastern League. Later in the summer, the short-season, Single-A team will play in Boise, Idaho, instead of Tri-City, Wash.

Strong starts. Outfielder Tim Wheeler had five home runs and 16 RBIs and hit .385 in his first 12 games for the Isotopes in Albuquerque. Shortstop Trevor Story had 18 hits and a .378 batting average in 13 games for the New Britain Rock Cats. In Single-A, outfielder Raimel Tapia had 12 RBIs and a .328 batting average after his first 13 games for Mo- desto and outfielder Wes Rogers hit .347 in 13 games for Asheville.
