Thaiss signed a minor-league contract with the Red Sox on Saturday that includes an invitation to spring training, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Thaiss has plenty of MLB experience, having played in 305 career regular-season games, mostly with the Angels. He's struggled with the bat, however, posting a .652 OPS with 23 homers, 95 RBI, seven steals and a 28.3 percent strikeout rate across 961 plate appearances. Boston is expected to begin the campaign with Carlos Narvaez (knee) and Connor Wong (hand) as its top two backstops, so Thaiss will probably enter spring training as insurance in case one of those two catchers is sidelined.

The Rays outrighted Thaiss to Triple-A Durham on Monday.

EDGE Analysis

He's no longer on the 40-man roster, but Thaiss will accept an outright assignment and remain in the organization as catching depth.

The Rays designated Thaiss for assignment Friday.

EDGE Analysis

Despite Danny Jansen being traded to Milwaukee on Monday, the Rays added to their backstop depth by acquiring Nick Fortes from the Marlins and Hunter Feduccia from the Dodgers. Thaiss is slashing .218/.349/.288 with one steal, one home run and 16 RBI in 190 plate appearances this season.

Thaiss is out of the lineup for Thursday's game against the Yankees, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Though the Rays recently shipped catcher Danny Jansen to Milwaukee while acquiring another backstop in Nick Fortes from Miami, Thaiss' playing-time outlook is unlikely to change dramatically. Thaiss had started in three of the previous four contests, but he's still likely to be stuck in a timeshare behind the dish with Fortes, who is regarded as the superior defender of the two.

Thaiss will start at catcher and bat ninth Monday against the Yankees.

EDGE Analysis

Thaiss was originally slated to sit out Monday's series opener, but he has been moved into the lineup after the Rays finalized a trade that sent Danny Jansen to the Brewers. Thaiss will be the team's starting backstop for the moment, though Ken Rosenthal of The Athletic relays that Nick Fortes is set to be acquired from the Marlins. Thaiss has a .641 OPS with one steal, one home run and 16 RBI in 181 plate appearances this season.

Thaiss went 1-for-4 with a triple and two RBI on Saturday against the Orioles.

EDGE Analysis

Thaiss remains the backup to Danny Jansen behind the plate for the Rays, though Saturday marked his fourth start in the last eight games. He delivered a two-RBI triple in the seventh inning to record his third multi-RBI performance of the campaign and second in his last four starts.

Thaiss went 3-for-4 with a walk, a double and four RBI in Friday's 14-8 win over Detroit.

EDGE Analysis

Thaiss gave the Rays a four-run lead in the first inning with a two-run double before driving in two more runs on separate RBI singles in the sixth and eighth. It was Thaiss's fifth multi-hit game and second multi-RBI contest this season. Since being acquired by the Rays in late May, he has gone 9-for-28 (.321) with four runs scored, five walks and five RBI.

Thaiss is out of the lineup for Wednesday's game against the Orioles.

EDGE Analysis

After going 0-for-2 while playing six innings behind the plate in Tuesday's 5-1 loss, Thaiss will retreat to the bench Wednesday while Danny Jansen gets the nod behind the plate. Since being acquired from the White Sox and activated May 28, Thaiss has started in seven of the Rays' ensuing 20 games and has batted .250 with no extra-base hits.

Thaiss was traded from the White Sox to the Rays on Tuesday in exchange for Dru Baker.

EDGE Analysis

Marc Topkin of the Tampa Bay Times speculates that Ben Rortvedt's roster spot will be in jeopardy when Thaiss joins the team, so the latter appears set to take over as Danny Jansen's backup. The lefty-hitting Thaiss slashed .212/.382/.294 with one home run, one steal and more walks (23) than strikeouts (21) in 110 plate appearances with the White Sox.

Thaiss is out of the lineup for Thursday's game against the Royals.

EDGE Analysis

Though Edgar Quero is viewed as the team's top backstop, the White Sox's willingness to deploy him as a designated hitter has allowed Thaiss to see more work than the typical No. 2 catcher. The left-handed-hitting Thaiss had started each of the last three games, but he'll be excluded from the lineup Thursday while the Royals send southpaw Kris Bubic to the hill.
