By sending infielder Josh Harrison to Triple-A Indianapolis on Thursday, the Pirates began a flurry of roster moves that will continue into next week.

Infielder Chase d'Arnaud will be called up from Indianapolis and will be in uniform for Friday night's game against the Boston Red Sox at PNC Park.

"These moves are the first in a series of probable moves to come in the next week to 10 days," general manager Neal Huntington said. "Josh did a solid job, and we expect he will help us at the major league level again this season."

Huntington declined to comment on what specific moves will follow. But an industry source confirmed the Pirates will call up outfielder Alex Presley and pitcher Brad Lincoln.

Presley will be promoted Tuesday, when the Pirates begin an interleague series in Toronto against the Blue Jays. To make room, infielder Pedro Ciriaco will be sent back to Indy.

Pitcher Brad Lincoln will be called up July 2 to make a spot start in the second game of a doubleheader against the Washington Nationals. Either d'Arnaud or a reliever will be sent down to clear roster space.

On July 3, Josh Harrison will be eligible for a recall to the Pirates, and he will rejoin the team at that point with Lincoln going back to Indy.

In a way, being the first one sent to Indy is a good sign for Harrison. By going down ahead Ciriaco, Harrison can return to the majors sooner.

It's a clear indication that Harrison fits better in the Pirates' plans this season than Ciriaco, who's gotten just six at-bats this year.
