Unfortunately, the Cubs don't have Casper Wells in the system any more. Wells, an outfielder who was in the Cubs' Spring Training camp as a non-roster invitee, pitched twice in relief last season for two different teams.

• Top prospect Kris Bryant drove in four runs, including three on his Southern League-leading 11th home run, and Stephen Bruno had four hits in Double-A Tennessee's 10-7 win over Jackson on Tuesday. Bryant now has 33 RBIs, tops in the league. Jose Veras, on a Minor League rehab assignment, started and threw one inning.
• Albert Almora, another highly regarded prospect, helped Class A Daytona beat Charlotte, 12-0. Almora was 3-for-5 with three doubles and four RBIs.
