ST. LOUIS (AP) -- The Chicago Cubs have activated right-hander Justin Grimm from the 15-day disabled list and recalled outfielder Matt Szczur from Triple-A Iowa.
Outfielder Junior Lake was optioned to Iowa and right-hander Anthony Varvaro was designated for assignment Wednesday. Varvaro was claimed off waivers from Boston on Sunday and added to the 25-man roster Tuesday but did not pitch.
Grimm (right forearm inflammation) made one rehab appearance with a scoreless inning Monday for Iowa at Nashville. Grimm made the opening day roster for the second straight season but had not pitched in the majors this year.
