Dean was released by the Twins on Wednesday, Brandon Warne of ZoneCoverage.com reports.

EDGE Analysis

Dean return from Korea on a minor-league contract this offseason but couldn't convince the Twins to keep him around. As a 29-year-old with a 6.28 ERA in his lone big-league season back in 2016, he's unlikely to make a significant impact at the top level this year.

Dean signed a minor-league deal with the Twins on Monday, Brandon Warne of ZoneCoverage.com reports.

EDGE Analysis

The 29-year-old lefty had spent seven years in the Twins' organizations, reaching the big leagues in 2016. He failed to impress at the highest level, finishing with a 6.28 ERA in 67.1 innings. He spent last season with the Kia Tigers of the KBO in South Korea, throwing 129.1 innings with a 6.26 ERA. He's unlikely to be anything more than organizational depth this season.

Dean has signed a contract with the KIA Tigers of the Korean Baseball Organization, Mike Berardino of the St. Paul Pioneer Press reports.

EDGE Analysis

Dean finally received his first shot in the majors last season, but struggled mightily in his only stint at the level. The 27-year-old southpaw allowed 13 home runs over 67.1 innings and posted a 6.28 ERA over 67.1 innings in the majors. He'll look for a better run overseas, but could find his way back to American baseball if he can find some success.

Dean was outrighted to Triple-A Rochester on Monday, Mike Berardino of the St. Paul Pioneer Press reports.

EDGE Analysis

Dean got his first taste of the big leagues this season, but he never was able to find a lot of success in the upper levels of the minor leagues. The left-hander will likely be relegated to acting as an organizational depth piece going forward.

Dean threw five innings in Game 1 of Thursday's doubleheader, allowing only one run on three hits and a walk while striking out five. He didn't factor into the decision.

EDGE Analysis

The southpaw kept a dangerous Detroit lineup at bay with his soft-tossing stuff before the Minnesota bullpen caved late in the game. While his 6.71 ERA over 59 innings probably should be better, given his 5.42 Fielding Independent Pitching, he's still not an exciting arm.

Dean will receive the start in the first game of Thursday's split doubleheader against the Tigers.

EDGE Analysis

Dean was bumped out of the rotation earlier in September and has most recently pitched out of the bullpen. It's quite possible he will be on a limited pitch count in his temporary return to the rotation Thursday.

Dean will be dropped from the rotation Monday against the Royals in favor of Jose Berrios, Phil Miller of the Minneapolis Star Tribune reports.

EDGE Analysis

Like Dean, Berrios has been hit hard during his starts with the Twins this season, but as a 22-year-old with plenty of prospect sheen, he'll get more opportunities than the 27-year-old Dean to prove himself. After getting blasting for six runs in back-to-back starts, Dean will likely work in long relief for the Twins until another chance to rejoin the rotation presents itself.

Dean (1-5) was lit up for six runs on seven hits and three walks over 4.1 innings in Wednesday's loss to the Indians. He failed to strike out a batter.

EDGE Analysis

The rookie southpaw's now posted consecutive six-run performances, allowing two homers both times. Across the board, Dean's numbers are about as ugly as any you'll see in the game, making it hard to imagine any fantasy format where he's worth owning. The Twins are rather thin on rotation options, but it's going to be hard for them to leave Dean in the rotation down the stretch. As a 27-year-old with ugly stats in the minors, he's hardly a key piece of their future.

Dean (1-4) gave up six earned runs on eight hits and a walk over three innings in Friday's 15-8 loss to the Blue Jays. He also recorded a strikeout.

EDGE Analysis

Dean got through the first unscathed, but it was downhill from there. Justin Smoak touched him up for a 407-foot three-run homer in the second, and Josh Donaldson followed with a 417-foot two-run shot later in the frame. Smoak then helped put an early end to Dean's night with an RBI single in the third. The 27-year-old southpaw now has a 9.00 ERA over the 10 innings since his Aug. 12 call-up from Triple-A Rochester.

Dean will start Friday's game against the Blue Jays.

EDGE Analysis

Hector Santiago -- who was initially slated to start Friday -- is dealing with a bruised thumb, so Dean will slot into the rotation for a spot start. The lefty has had a rocky go of things in six starts at the major league level this season, posting a 5.81 ERA and 1.52 WHIP while allowing five home runs in 31 innings.
