Rollins was claimed off waivers by the Cubs on Friday.

EDGE Analysis

The left-hander spent the bulk of 2016 at Triple-A, but his brief cup of coffee at the major league level was disastrous, as he was only able to muster a 7.71 ERA and 1.9 HR/9. That being said, the Cubs really don't have many lefties in their bullpen, so Rollins will likely be in contention for a big league roster spot as long as he can keep the ball in the park.

Rollins was recalled from Triple-A Tacoma on Sunday, MLB.com reports.

EDGE Analysis

Rollins struggled during his nine appearances with the Mariners earlier this season, putting up a 7.04 ERA and 2.22 WHIP across 7.2 innings. Given his lack of prior success at the MLB level, Rollins will likely be limited to low-leverage duty out of the bullpen throughout September.

Rollins was optioned down to Triple-A Tacoma on Friday.

EDGE Analysis

The Mariners wanted to add extra depth to their bench for an upcoming road trip, and Rollins, who has bounced between the majors and Triple-A all year, was the one sent down. Outfielder Guillermo Heredia was called up in his place.

Rollins was recalled from Triple-A Tacoma on Saturday.

EDGE Analysis

Rollins was promoted in a corresponding move to Ketel Marte being placed on the 15-day DL with an illness. The 26-year-old southpaw has been bouncing between the Mariners and Tacoma all season, and will slide back into a relief role with the club while he's there. Throughout the 2016 season, Rollins has posted a 4.05 ERA and a 1.95 WHIP during 6.2 innings with Seattle.

Rollins was optioned to Triple-A Tacoma on Wednesday.

EDGE Analysis

The Mariners made a series of moves Wednesday, including optioning Rollins, Jesus Sucre and Daniel Robertson to Triple-A. Rollins was a solid bullpen option in limited action (4.05 ERA, 6.2 innings), but he's found more success at the Triple-A level, where he holds a 2.05 ERA and 0.717 WHIP on the year.

Rollins was recalled by the Mariners on Wednesday, Greg Johns of MLB.com reports.

EDGE Analysis

Rollins has pitched well in his 34.2 innings between Triple-A and the majors this season. After being demoted on Tuesday, Rollins was recalled as Taijuan Walker was placed on the 15-day disabled list. Rollins will slot back in to the bullpen as it looks like Mike Montgomery will start Sunday in Kansas City.

Rollins was optioned to Triple-A Tacoma on Tuesday, Greg Johns of MLB.com reports.

EDGE Analysis

The M's added some bench depth with Shawn O'Malley (foot) banged up, promoting Dan Robertson and sending Rollins back to Tacoma. Rollins made three scoreless appearances during his most recent stint with the big club, but he did walk three over 2.2 innings. He's issued just one walk in 30.2 innings with Tacoma this season and figures to get another chance before too long.

Rollins was recalled from Triple-A Tacoma on Friday.

EDGE Analysis

The Seattle bullpen was taxed Thursday after Adrian Sampson suffered an injury during pregame warmups, and Rollins and Donn Roach were brought up as reinforcements. Rollins has posted a 2.05 ERA and 0.72 WHIP in 24 appearances with Triple-A Tacoma but figures to work primarily in the middle innings.

Rollins was optioned to Triple-A Tacoma on Saturday.

EDGE Analysis

The move was announced Friday night, but the Mariners have now made it official, as Rollins heads down to Tacoma to clear room on the 25-man roster for Adrian Sampson, who will make his MLB debut Saturday. Rollins is a candidate to return to the Mariners at some point later in the summer, but he's unlikely to provide much more than spot duty as a middle reliever.

Rollins will be optioned to Triple-A Tacoma so that Adrian Sampson can start Saturday against Boston, Bob Dutton of The News Tribune reports.

EDGE Analysis

Rollins is still awaiting his 2016 major league debut as he continues to bounce back and forth from Seattle to Tacoma. Even if given a chance, however, the 26-year-old will likely just serve as middle-inning relief.
