Red Sox manager Alex Cora said Friday that Mayer will have to earn his way onto the Opening Day roster, Christopher Smith of MassLive.com reports.

Mayer remains a likely bet to be in Boston's lineup on Opening Day in Cincinnati, but a job will not be handed to him, with Cora noting the young infielder must improve his offense after posting a 80 wRC+ in the majors last season. What position Mayer is likely to fill hasn't been determined yet. The Red Sox had previously indicated a desire to put him at third base, but early on in camp Mayer has mostly played second base, with Caleb Durbin handling the hot corner.

The Royals signed Diaz to a minor-league contract Friday that includes an invitation to spring training.

Diaz is expected to report to Royals camp next week. The 35-year-old appeared in 106 regular-season contests for the Padres last season, slashing .204/.270/.337 with nine long balls. Unless the Royals carry three catchers on their Opening Day roster, Diaz is likely ticketed for Triple-A Omaha.

Cole (elbow) will throw a live batting practice session Friday, Brendan Kuty of The Athletic reports.

It will be Cole's first time facing hitters since last March's Tommy John surgery with an internal brace. The veteran hurler's rehab has gone swimmingly to this point, and he will continue to check off boxes as he eyes a season debut in late May or early June.

Red Sox manager Alex Cora on Thursday mentioned Romero as one of the players that has stood out in camp thus far, Jen McCaffrey of The Athletic reports. Most notable to the manager was that Romero used the offseason to bulk up, per Rob Bradford of WEEI.com.

"You see the physicality of Romero," Cora said. "He's strong, stronger than last year. From me, I want to see him at second base and see how it plays out. He did an amazing job (adding strength) in the offseason." Romero had a fully healthy season in 2025, his first since being selected 24th overall in 2022. The 22-year-old infielder posted a .751 OPS with 17 home runs -- third most in the system -- over 111 games between stops at Double-A Portland and Triple-A Worcester while seeing time at second base, shortstop and third base. Second base was an unsettled spot for Boston last season, but either Marcelo Mayer or Caleb Durbin should handle those chores in 2026, with the other at third base. Romero, who currently does not have a spot on the 40-man roster, might put himself in contention for a call-up should the Red Sox have a need for an infielder.

Red Sox manager Alex Cora said Thursday that coaches are working with Oviedo to be more explosive with his delivery, Christopher Smith of MassLive.com reports. "Just a big dude that we gotta get moving," Cora said of the 6-foot-6, 275-pound right-hander. "Not work faster as far as like tempo, but move faster. And I think we accomplished that today."

Oviedo threw a two-inning live batting practice Thursday, and the manager said he's getting closer to what coaches are looking for. Cora also raved about the right-hander's extension, but strike-throwing remains key for the hurler, whose first spring start is scheduled for Wednesday against the Twins. Oviedo appears to be the frontrunner for a spot at the back end of the rotation. One candidate, Kutter Crawford (wrist), could open the season on the injured list, and two others, Connelly Early and Payton Tolle, may begin the year at Triple-A Worcester. Left-hander Patrick Sandoval is also in the mix, but he missed all of 2025 with an elbow injury.

Cannon is competing for a rotation spot during spring training, Scott Merkin of MLB.com reports.

Cannon began the 2025 season in the White Sox's rotation but was demoted to the bullpen and also had a stint in the minors in the second half of the campaign. Merkin suggests the White Sox have as many as 10 pitchers competing for rotation spots, and Cannon's chances of securing a role to begin the season may not be very strong after Chicago added Anthony Kay, Erick Fedde and Sean Newcomb this offseason. Nevertheless, Cannon will get his first chance to improve his chances in Friday's Cactus League debut against the Cubs.

Manager John Schneider said Thursday that Bieber (forearm) has progressed to throwing from 120 feet, Keegan Matheson of MLB.com reports.

The team has already confirmed that Bieber will begin the regular season on the injured list due to forearm fatigue -- something he pitched through during Toronto's playoff run in 2025. Schneider added that he expects Bieber to begin throwing bullpen sessions within the next two weeks, at which point more information may emerge regarding how much time the right-hander will miss to begin the new campaign.

Montero has yet to report to the Yankees' camp due to visa problems, Bryan Hoch of MLB.com reports.

Montero inked a minor-league contract with an invitation to spring training last week, but he's yet to report. It shouldn't greatly affect his preparation as long as his absence doesn't stretch on too long, but it will not help Montero's longshot bid to win a bullpen job.

McArthur (elbow) is considered healthy but will be eased into a throwing program this spring, Jaylon T. Thompson of The Kansas City Star reports.

McArthur had surgery last offseason to insert two screws into his right elbow to help stabilize a stress fracture. He then had another procedure in July to remove the screws after they had caused an allergic reaction in his elbow. McArthur wound up not pitching at all in 2025, but he's been throwing off the mound for a few months. He was also diagnosed with a Grade 1 UCL sprain prior to the first elbow surgery, so it's no surprise the righty is being slow-played this spring after all the missed time. McArthur should have enough time to be ready for Opening Day if he can avoid setbacks.

Erceg (shoulder) is throwing off the mound in Royals camp, Jaylon T. Thompson of The Kansas City Star reports.

Erceg's 2025 season ended in mid-September due to a right shoulder impingement, but he doesn't seem to have any restrictions in the early stages of spring training. The reliever collected a 2.64 ERA and 22 holds last season but saw a year-over-year drop in strikeout rate from 28.5 percent to 19.3 percent. As long as he's healthy, Erceg should produce more swing and miss in 2026 and will serve as a setup man ahead of closer Carlos Estevez.
