Quero visited Driveline Baseball last week with a goal of increasing his bat speed and improving his launch angle, Alden Gonzalez of ESPN.com reports.

Quero had a healthy 46.3 percent hard-hit rate and 90.4 mph average exit velocity during his rookie season, but his bat speed ranked in the fourth percentile and his average launch angle ranked in the seventh percentile. An assessment determined Quero was lacking lower-body strength, so he was given drills to help increase his explosiveness and add more bat speed. He also had a pull-air rate of just 7.8 percent last season, and the instructors at Driveline worked with him on catching the ball in front of the plate in order to pull the ball with authority. Quero had a respectable .268/.333/.356 batting line in his rookie season and sported a 17.9 percent strikeout rate, but he swatted just five home runs. If the young switch hitter is able to boost his power while maintaining his quality eye at the dish, he could break through. Quero is set to share catching duties with Kyle Teel in 2026 and is also expected to see ample starts at designated hitter for the White Sox.

Evans underwent UCL reconstruction surgery with an internal brace Jan. 23 on his right elbow.

Evans missed several weeks during the second half of last season with right elbow inflammation, so it's possible he had UCL damage for a while that was only recently discovered. He will miss the entire 2026 season, and given the timing of the procedure, could get a late start to the 2027 campaign, as well. Evans had been likely to open the upcoming season at Triple-A Tacoma, but his absence is a blow to the Mariners' pitching depth. The 24-year-old posted a 4.32 ERA and 59:31 K:BB over 81.1 innings covering 15 starts and one relief outing last season.

The Blue Jays signed Stubbs to a minor-league contract Friday that includes an invitation to spring training.

Stubbs made his major-league debut in 2025 with the Nationals, going hitless in three plate appearances. The 29-year-old will merely be organizational catching depth for the Blue Jays at Triple-A Buffalo.

The Athletics signed Wilson to a seven-year, $70 million contract extension Friday, Jeff Passan of ESPN.com reports. The deal includes a club option for 2033.

Wilson finished runner-up to teammate Nick Kurtz in the American League Rookie of the Year voting in 2025 after slashing .311/.355/.444 with 13 home runs, five stolen bases and a 27:39 BB:K over 125 contests in his first full major-league season. The 23-year-old's upside is capped due to his lack of power and mediocre defense at shortstop, but Wilson has some of the best contact skills in the game. It's a contract that should turn out to be very team-friendly as long as he stays healthy.

The Mariners have extended Emerson an invitation to major-league camp during spring training.

Fellow top prospects Kade Anderson, Lazaro Montes and Ryan Sloan, among others, will join the 20-year-old infielder in big-league camp. Emerson has the best opportunity of all of them to break camp with the big club, as he is expected to be in the thick of the competition for the Mariners' third-base job. He slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors in 2025.

The Guardians have extended Bazzana an invitation to big-league camp in spring training.

The No. 1 overall pick in the 2024 First-Year Player Draft, Bazzana somewhat surprisingly was not invited to spring training last year, but he will be with the big club in camp this time around. Bazzana has had an underwhelming start to his pro career, having slashed .245/.389/.424 with nine homers and 12 steals in 2025 while being limited to 84 games due to oblique issues. He finished last season at Triple-A Columbus and is likely to head back there to begin the 2026 season, but Bazzana is could debut with Cleveland at some point during the summer.

The Rays have extended Hopkins an invitation to big-league camp in spring training, Marc Topkin of the Tampa Bay Times reports.

Hopkins was excellent at Double-A Montgomery this past season, collecting a 2.72 ERA and 141:60 K:BB over 116 innings. He has some of the best stuff of any pitching prospect in baseball and could become a legitimate ace if he's able to throw enough strikes. Hopkins isn't going to break camp with the big club, but there's a good chance he will debut at some point in 2026.

Bradford (elbow) could begin a rehab assignment around Opening Day, Kennedi Landry of MLB.com. Rangers president of baseball operations Chris Young indicated that May is the target for the left-hander's return.

Bradford, who recently threw a bullpen session, missed all of 2025 after sustaining an elbow injury during spring training that required an internal brace procedure in June. He showed promise in 2024, posting a 3.54 ERA over 76.1 innings, but missed months due to back and rib injuries. Texas bolstered its rotation during the offseason with the acquisition of MacKenzie Gore from the Nationals and may not have a spot in the rotation for Bradford upon his return. Beyond the top three of Jacob deGrom, Nathan Eovaldi (groin) and Gore, other candidates for the back end of the rotation include Jack Leiter, Kumar Rocker, Jacob Latz, Austin Gomber and Cal Quantrill .

Quantrill signed a minor-league deal with the Rangers on Thursday, which includes an invitation to spring training, Evan Grant of The Dallas Morning News reports.

Quantrill closed the 2025 season in the Rangers' organization, making two starts at Triple-A Round Rock. He looks unlikely to break camp in the rotation after posting a 6.04 ERA over 26 appearances between Atlanta and Miami last year, but he could make an impact at some point in the new campaign.

Teng was traded from the Giants to the Astros in exchange for a minor-league player on Thursday, Robert Murray of FanSided.com reports.

Teng has experience as both a reliever and starter in the majors, and he worked primarily out of the Giants' rotation toward the end of the 2025 season. He still has two minor-league options remaining, so there's a strong chance Teng begins the season with Triple-A Sugar Land. However, he should contribute to the big-league club at some point in 2026.
