Thielbar (oblique) threw a bullpen session Tuesday, Dan Hayes of The Athletic reports.

EDGE Analysis

The 36-year-old southpaw reportedly reached the mid-80s and was satisfied with his intensity. Thielbar will throw another bullpen session within the next few days, at which point the Twins will determine his next steps. Thielbar has been on the injured list since May 5 with a right oblique strain.

Thielbar (oblique) has resumed playing catch and is expected to throw off the mound next week, Betsy Helfand of the St. Paul Pioneer Press reports.

EDGE Analysis

Thielbar is currently on the injured list with a right oblique strain, but the strain is considered "moderate" and it's a positive development he's back to throwing. It seems likely Thielbar will need a rehab assignment, but he could be back as an option for the Minnesota bullpen around the start of June.

Thielbar has been diagnosed with a moderate strain of his right oblique and won't throw for a week before being evaluated, the Minneapolis Star Tribune reports.

EDGE Analysis

It's an encouraging report, but he's still likely out several weeks since it will take him some time to ramp back up again after the layoff. Thielbar will be missed as a key lefty in the bullpen with a stellar 1.80 ERA and 0.90 WHIP across 11 appearances.

Thielbar was placed on the 15-day injured list with a right oblique strain, Do-Hyoung Park of MLB.com reports.

EDGE Analysis

The severity of Thielbar's injury is unclear at the moment, so there's no telling if he will require more than a minimum stay on the IL. Either way, it's a tough blow to the Twins' bullpen as Thielbar currently holds a 1.80 ERA and 0.90 WHIP across 11 appearances.

EDGE Analysis

Thielbar is off to a strong start to the season with a 2.25 ERA and 10 strikeouts in eight innings with two walks. He's working as the top lefty in the bullpen, but may not be in the mix for saves behind Jorge Lopez, Griffin Jax and Jhoan Duran.

Thielbar threw a scoreless inning with a strikeout in Thursday's win over Kansas City.

EDGE Analysis

Thielbar took over for starter Pablo Lopez in the sixth inning. Theilbar picked up where he left off last season when he posted a 12.1 K/9 and 15% swinging strike rate that was top 30 among qualified relievers. He'll reprise his role as Minnesota's top lefty reliever and will be used anywhere in the middle to late innings.

Thielbar signed a one-year, $2.4 million contract with the Twins on Friday to avoid arbitration, Aaron Gleeman of The Athletic reports.

EDGE Analysis

Thielbar has been one of the most consistent pieces of the Twins' bullpen for the past three seasons, keeping his WHIP right around the 1.15 mark. The veteran southpaw will turn 36 at the end of the month, so it's worth questioning how much left he has in the tank. But for now, a 2.42 FIP keeps him in a nice position as one of Minnesota's top relievers.

Thielbar (hamstring) was reinstated from the 15-day injured list Wednesday, Do-Hyoung Park of MLB.com reports.

EDGE Analysis

Thielbar was effective prior to the All-Star break, allowing two hits and two walks while striking out six in 4.1 scoreless innings over his last four appearances. However, he's dealing with a hamstring issue that will keep him out until at least early August. Yennier Cano was recalled from Triple-A St. Paul to take Thielbar's place in the bullpen.
