HOUSTON — The Cubs’ back-to-back blowout losses in Minnesota led to a series of roster moves Monday as they reinforced their taxed bullpen.
They optioned right-handed starter Hayden Wesneski to Triple-A Iowa and put veteran reliever Brad Boxberger on the 15-day injured list with what they called a strained right forearm. They recalled Jeremiah Estrada and selected right-hander Nick Burdi from Iowa. And to make room on the 40-man roster for Burdi, they transferred Adrian Sampson (right meniscus) from the 15-day IL to the 60-day IL.
