the reason Shark got promoted: "His last five outings have been real good," Cubs player development director Oneri Fleita said.
In those five games, Samardzija has given up eight earned runs over 27 1/3 innings on 16 hits and 10 walks while striking out 16.
Hill to mesa because: The Iowa team is a little shorthanded with Sean Marshall set to be promoted on Tuesday to replace Carlos Zambrano in the Cubs' rotation, and Hill being sent to Mesa, Ariz., for some extra tutoring.
Hill will work with Minor League pitching coach Rick Tronerud and pitching coordinator Mark Riggins. The left-hander, who opened the year in the Cubs' rotation but struggled to a 1-0 record and 4.12 ERA in five starts, was 2-4 with a 5.88 ERA in seven games at Iowa. In his last start against New Orleans, he gave up six runs on three hits and four walks and couldn't finish the first inning. He has walked 28 and given up 22 hits in 26 innings at Iowa.
also on Felix Pie: Pie, who was batting .222 in 36 games at Iowa, also was headed to Mesa, Ariz., to undergo an MRI on his left hand, and will rehab there. Fleita said Pie either jammed his hand or injured it on an awkward swing and has been playing in pain for a few games.
