10:21pm: Bruce Levine of ESPN Chicago reports that Lopez will earn $900K if he is on the big league roster or $235K in the minors.
4:06pm: The Cubs have signed Rodrigo Lopez to a minor league deal with an invitation to spring training, according to Fernando Ballesteros at the Mexican baseball magazine Puro Béisbol (via Twitter). The team had been reported to be interested in bringing back the journeyman pitcher, and Ballesteros reported on Monday that rumors of the signing began circulating in the Mexican media over the weekend.
Lopez, 36, signed a minor league deal with the Braves last January but didn't make the roster out of spring training. After being traded to the Cubs in May, he played the role of a softer-tossing version of new Red Sox swingman Vicente Padilla, working in long relief and occasionally closing while waiting out a spot in the rotation. Lopez ended up logging 16 starts over the late summer, earning a 4.42 ERA with 5.0 K/9 and 2.7 BB/9 over 116 innings.
