Perdomo batted second and went 1-for-3 in Friday's Cactus League opener against the Rockies.

Perdomo should be a regular presence in spring lineups over the next two weeks, before he joins the Dominican Republic in the World Baseball Classic. He's expected to bat leadoff against right-handers and second against left-handers for Arizona during the regular season.

Alexander is likely to be the Orioles' Opening Day second baseman in place of the injured Jackson Holliday (hand), Brendan Mortensen of MASNSports.com reports.

Holliday will begin the season on the injured list following hamate surgery, though his absence could be relatively brief. Jordan Westburg (elbow) had been under consideration for a move from third base to second base, but he's now shelved himself for at least the first month of the season. Acquired from the Diamondbacks via trade earlier this month, Alexander slashed .230/.323/.383 with seven homers and four steals over 74 games in 2025.

Sweeney will have his throwing program paused due to a right shoulder strain, Cody Stavenhagen of The Athletic reports.

It's unclear when Sweeney might be ready to throw again, much less play in games. The 25-year-old was already lower down in the pecking order at shortstop for the Tigers, and this setback won't help his chances at earning a spot on the Opening Day roster.

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.

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.

The Cubs announced Wednesday that Machado has been named the manager of their rookie-level Arizona Complex League affiliate, Maddie Lee of the Chicago Sun-Times reports.

Machado's move into the coaching ranks signals the end to a 17-year professional playing career. The 33-year-old infielder played exclusively at Triple-A Iowa in the Cubs organization last season, but he spent parts of five seasons in the big leagues from 2015 through 2022. Between stops with the Tigers and Giants, Machado slashed .226/.285/.292 with two home runs and three steals over 177 career games.

Pirates manager Don Kelly said Wednesday that it "would be a tough ask" for Griffin to make the Opening Day roster, Andrew Fillipponi of 93.7 The Fan reports.

Griffin is a 19-year-old with only 21 games of experience above A-ball, so cracking the Opening Day roster would indeed be a difficult leap. It's also not a surprise that Kelly is tamping down expectations for the top prospect this early in spring training. It should become clearer the deeper we get into camp as to whether Griffin has a real chance to head north with the big club. Griffin hit .333/.415/.527 with 21 home runs and 65 stolen bases across three levels in his first professional season in 2025.

The Blue Jays claimed Cowles off waivers from the Cubs on Wednesday.

Cowles slashed just .235/.300/.371 with nine home runs and 18 steals over 462 plate appearances at hitter-friendly Triple-A Iowa in 2025. The 26-year-old has some defensive versatility with the ability to handle shortstop, second base and third base. He's likely ticketed for Triple-A Buffalo to kick off the 2026 season.

Holliday will have the stitches removed from his surgically repaired right hand Monday, Roch Kubatko of MASNSports.com reports.

Coming back from hamate bone surgery, Holliday will be cleared to gradually begin activities after the stitches are out. The 22-year-old infielder will begin the season on the 10-day injured list, but it could be a minimum-length stint or close to it. Jordan Westburg (oblique) and Blaze Alexander are candidates to play second base in Holliday's stead.

Swanson is willing to swap some power for more contact in 2026, Bruce Levine of Marquee Sports Network reports.

Swanson has clubbed at least 22 home runs in four of the past five seasons, but he also has a strikeout rate over 25 percent during that span and would like to cut that down. The 32-year-old's chase rate has been consistently above league average, but his in-zone contact rate has been well below average, as he ranked 129th out of 144 qualifiers in that metric in 2025. Swanson went 20-20 last season but still finished outside the top-12 in fantasy at a loaded shortstop position.
