The Cubs made a pair of waiver claims on Friday, grabbing catcher Ryan Lavarnway and outfielder Shane Peterson while designating right-handed pitcher Donn Roach and infielder Logan Watkins for assignment.
Lavarnway, 27, spent the last seven seasons in the Red Sox organization and played just shy of 100 games in the majors. He hit .201 with five homers and 34 RBIs during his time with the Red Sox.
Lavarnway spent most of 2014 with Triple-A Pawtucket, hitting .283 with three homers, 20 RBIs and a .389 on-base percentage in 62 games.
Peterson, 26, hit .308 with 40 doubles, 11 homers and 90 RBIs at Triple-A Sacramento last season. He earned Pacific Coast League midseason and postseason All-Star honors.
The Cubs claimed Roach off waivers in November. Watkins, 25, batted .233 during big-league stints the last two seasons.
