• Cubs pitcher Scott Baker gave up one run over four innings for Class A Kane County in a rehab outing Friday.

Baker, in his second Minor League rehab stint this season coming back from Tommy John surgery on his right elbow, gave up four hits, walked two and struck out three in his longest rehab outing. Beloit's Matt Olson accounted for the run, hitting a solo homer off Baker in the second.

Baker's rehab was moved to Kane County because the weather interfered with his starts at High A Daytona.

• Ryan Sweeney worked out at Petco Park on Friday before a scheduled rehab assignment Saturday with the Cubs' Rookie League team in Mesa.

Sweeney, sidelined since June 30 with fractured left ribs, was expected to join the Cubs in September.

Third baseman Luis Valbuena also was at the Cubs' facility in Mesa to start taking more batting practice there. However, he was not ready for games. Valbuena has been sidelined since Aug. 3 with a right oblique strain.
