Analysis: Cheng was with the big club for a little over a week and didn't play much, going hitless in seven at-bats. He's clearing out to make room on the roster for Jared Triolo's (back) return from the 10-day injured list.

Analysis: Cheng will head to the big leagues for the first time, joining the Pirates as a replacement for utility man Jared Triolo (back), who was placed on the injured list. The 23-year-old is capable of playing second base, third base and shortstop, but he's not included in the lineup for Monday's game against the Cardinals and may not be in store for regular playing time during his stint with the big club.
