Rays designate RHP Preston Guilmet for assignment.
Guilmet was optioned to Triple-A Durham last week, but this move takes him off the 40-man roster with John Jaso (wrist) returning from the 60-day disabled list. There's a chance he could pass through waivers unclaimed.
Rays placed OF Steven Souza on the 15-day disabled list, retroactive to July 6, with a right pinkie finger laceration.
Souza suffered the injury when he was hit by a pitch on Sunday. The good news is that he's not dealing with a fracture or tendon damage, but he'll get some extended rest. The 26-year-old is batting .210/.301/.417 with 15 homers, 33 RBI, and 10 steals over 79 games this season.
Rays activated C John Jaso from the 60-day disabled list.
Jaso has been out since Opening Day with a bruised left wrist, but he's finally back to 100 percent. He figures to see semi-regular at-bats out of the DH spot, which makes him a sneaky add in deeper fantasy leagues.
Addison Russell is not in the starting lineup for the first game of Tuesday's doubleheader against the Cardinals.
Jonathan Herrera will start at second base and bat ninth. Russell is currently mired in a 2-for-34 slump, but he figures to play in the second game.
Rafael Soriano tossed a scoreless inning Monday in his first appearance with Double-A Tennessee.
Soriano, who signed with the Cubs last month, allowed one hit and struck out three batters in the inning. The veteran reliever figures to make a handful of tune-up appearances, which puts him on track to join the major league roster after the All-Star break. Cubs manager Joe Maddon isn't going with a set closer right now, so it's possible Soriano could get some save chances in the second half.
Lorenzo Cain (hamstring) is not in the starting lineup for the first game of Tuesday's doubleheader against the Rays.
Cain aggravated his left hamstring on Sunday and is expected to miss a couple of days. Paulo Orlando will start in center field.
Salvador Perez is not in the starting lineup for the first game of Tuesday's doubleheader against the Rays.
Drew Butera will start behind the plate and catch Chris Young. Perez should be in the lineup for Game 2.
Chris Coghlan is not in the starting lineup for the first game of Tuesday's doubleheader against the Cardinals.
Coghlan currently leads MLB with 145 consecutive games played, but that streak could come to an end Tuesday. Chris Denorfia will start in left field against southpaw Tyler Lyons.
