Means (elbow) is expected to begin throwing bullpen sessions at some point this month, MLB.com reports.

As of April 30, Means had been responding well since starting up his throwing program, and he had increased his throwing distance off flat ground to 120 feet. Assuming he's avoided any setbacks in his recovery from Tommy John surgery over the ensuing two weeks, he could take the next step forward in the rehab process by getting back on the mound. Means still has multiple checkpoints to hit, but a late-season return from the 60-day injured list remains a possibility for the veteran lefty.

Baldwin is set to see more playing time, David O'Brien of the Athletic reports.

Atlanta manager Brian Snitker indicated Baldwin would be back behind the plate Thursday after he went 3-for-4 with his fourth homer of the season Tuesday, with Sean Murphy getting the nod behind the plate Wednesday. As long as he's contributing with his bat, the rookie backstop should continue to see an equal share of the workload against right-handed pitching, although he has yet to get a start against a lefty. Through his first 25 big-league games, Baldwin is slashing .329/.382/.557 with a 6:13 BB:K.

Fitts (pectoral) has been throwing up-and-down bullpen sessions and is expected to be cleared to face hitter soon, MLB.com reports.

Fitts is a month removed from landing on the 15-day injured list with a right pectoral strain and has progressed well lately. The right-hander will require a rehab assignment before being activated and might be optioned to Triple-A Worcester rather than rejoining the Red Sox.

Red Sox manager Alex Cora believes Gonzalez (back) will be ready to return from the 10-day injured list when first eligible May 18, MLB.com reports.

Gonzalez first suffered a back injury one week ago and officially landed on the IL this past weekend. It's not clear whether he will need to play any rehab games before being activated, but the infielder appears on track for activation Sunday. Once activated, Gonzalez should regain his standing as Boston's top option at first base.

Guardians manager Stephen Vogt said that Allard is " definitely an option" to enter the rotation after Ben Lively (forearm) was placed on the 15-day injured list Tuesday, Tim Stebbins of MLB.com reports.

Triple-A Columbus lefty Doug Nikhazy and rehabbing right-hander Slade Cecconi (oblique) also represent options to fill the opening in the big-league rotation, but Allard may have the edge since his pitching schedule had been aligned with Lively. After making four starts for Columbus before getting called up in late April, Allard has excelled while working in a long-relief role for Cleveland, turning in a 1.20 ERA and 0.87 WHIP over 15 frames. When Lively left his latest start Monday against the Brewers after working just three innings, Allard followed him with three scoreless innings of his own. Since he hasn't tossed more than 52 pitches in any outing in May, Allard could be on a light workload restriction if he's called upon to start when Lively's next turn comes up this weekend in Cincinnati.

Thomas (wrist) will require at least a week's worth of rehab games with Triple-A Columbus before being activated from the 10-day injured list, MLB.com reports.

Thomas began his rehab assignment Tuesday with Columbus, going 0-for-3 with two strikeouts out of the designated hitter spot. The Guardians have a series in Minnesota that runs through next Wednesday, so the earliest Thomas rejoins the Guardians might be for the start of their series in Detroit on May 22. Angel Martinez has played well in center field since Thomas injured his right wrist a month ago, so Thomas might not be guaranteed regular playing time once he returns.

Meckler has not played for Triple-A Sacramento since March 29.

He was placed on the 7-day injured list March 30, and then there was an erroneous transaction note on his MiLB page saying he was activated April 3, but he's still tending to the undisclosed injury six weeks after suffering it. Meckler went 3-for-6 with two walks, two steals and zero strikeouts in two games before getting hurt.

Moreno is not in the lineup for Wednesday's game in San Francisco.

Moreno caught each of the first two games of the series but will get a breather for Wednesday's afternoon tilt. Jose Herrera will do the catching and bat ninth for the Diamondbacks.

Sykora (hip) has been activated from the 7-day injured list and assigned to Single-A Fredericksburg, Spencer Nusbaum of The Washington Post reports.

Sykora made two starts with the Nationals' Florida Complex League affiliate after recovering from hip labrum surgery, permitting just one run with a 14:1 K:BB over five innings. The 21-year-old has some of the best upside of any pitching prospect in the minors and will start for Fredericksburg on Wednesday.

Pillar (back) will begin a rehab assignment with Double-A Frisco on Wednesday.

Pillar has missed the last week of action with lower-back inflammation but is ready to test himself in a game setting. He is eligible for activation from the 10-day injured list at any point and shouldn't need many rehab at-bats before rejoining the Rangers' active roster.
