The Pirates have optioned RHP Nick Kingham to Triple-A Indianapolis and outfielder/infielder José Osuna is "expected to be recalled" tomorrow in time for the game against the White Sox in Chicago.
Osuna has spent all but one day of the 2018 season with Indianapolis. He was recalled by Pittsburgh on 4/25 to serve as the 26th man for the second game of a doubleheader against Detroit and hit a three-run homer in his first at bat while playing right field that night. Osuna was named the International League's Player-of-the-Month for April after hitting .361 and leading the league in extra-base hits (12) and slugging percentage (.656); he was also tied for second in RBI (16), doubles (nine) and total bases (40). 
In 23 games overall with Indianapolis, Osuna has hit .359 (28-for-78) with 12 doubles, three home runs, 18 RBI and a 1.037 OPS. Defensively, Osuna has made 17 appearances at third base and four in right field while playing with Indy.
