Jeffers is not in the Twins' starting lineup against the Blue Jays on Friday.

Jeffers will be in the dugout for Friday's weekend opener while Christian Vazquez serves behind home plate and bats ninth. Jeffers has gone 6-for-23 with four runs, one home run and two RBI over his last six games.

Smith is out of the lineup for Friday's game against the Cardinals.

Realmuto (groin) will bat fifth and catch Friday against Pittsburgh, Paul Casella of MLB.com reports.

The Rockies released Stallings on Friday.

With the Rockies struggling to win games and Stallings owning a .396 OPS in 93 plate appearances, Colorado has decided to go elsewhere for the backup catcher role. Braxton Fulford will fill the position while Stallings hits the open market. The 35-year-old catcher slashed .263/.357/.453 with Colorado last season, and a team could look to take a chance on the veteran in hopes of him figuring it out at the plate.

Teel is starting behind the plate and batting sixth Friday against the Royals.

The 23-year-old will immediately enter the starting lineup after being added to the big-league roster Friday, and he'll do the catching for right-hander Davis Martin. Teel had an .886 OPS with eight homers and seven steals in 50 games with Triple-A Charlotte prior to being promoted, and he could take the No. 1 catching job from Edgar Quero with a strong start to his MLB career.

The Rockies recalled Fulford from Triple-A Albuquerque on Friday.

Fulford will take over as Colorado's backup catcher after the Rockies released Jacob Stallings. Fulford made his MLB debut earlier this season and went 1-for-8 with a solo home run over four games. However, he's slashing .314/.393/.608 in 117 plate appearances with Albuquerque this season.

Ruiz is out of the lineup for Friday's game against the Rangers.

Ruiz is absent from the starting nine for the second time in three games, as Riley Adams steps in behind the dish. Ruiz is 4-for-31 (.129) at the plate over his last eight games.

The Reds designated Wynns for assignment Friday.

Wynns had been serving as a depth piece since Tyler Stephenson was activated from the injured list May 2, and he hasn't had multiple at-bats in a game since May 6. He'll yield his spot on the active roster to Christian Encarnacion-Strand (back), who's being activated from 10-day injured list.

The White Sox optioned Lee to Triple-A Charlotte on Friday.

The 26-year-old will lose his place on the MLB roster Friday with prospect Kyle Teel being called up for his first taste of the majors. Lee was reinstated from the injured list last week after going down with an ankle injury in early April, and he'll head to the minors with a .250/.300/.357 slash line in 31 big-league plate appearances this season.
