Young (undisclosed) suffered a contusion during his collision with Anthony Rizzo in Thursday's spring game, Carrie Muskat of MLB.com reports.

There still hasn't been word on where exactly Young is dealing with this contusion, but it doesn't seem to be too serious. Consider him day-to-day.

Tomlinson went 2-for-3 with a stolen base and a run scored in Thursday's win over Seattle.

With the Giants' starting infield set for Opening Day, Tomlinson is expected to serve as the club's primary backup infielder. He doesn't offer much in terms of power (.314 slugging percentage in 194 at-bats last season), but he arguably has the most speed of any player on San Francisco's projected roster. The 27-year-old's backup role will keep him off fantasy radars, but he can provide some steal potential should he fall into playing time at any point this year.

Rosario (groin) is scheduled to serve as the designated hitter during Friday's Grapefruit League game and then play shortstop Saturday, Anthony DiComo of MLB.com reports.

Manager Mickey Callaway said that he will likely only receive 1-to-2 at-bats Friday before taking the field for the first time since last weekend during Saturday's contest against the Yankees. The shortstop has been dealing with groin soreness but barring any sort of setback this weekend, he should be back to full health well before Opening Day.

Young was removed from Thursday's spring game early after being clipped by Anthony Rizzo in pursuit of a foul popup, Mark Gonzales of the Chicago Tribune reports.

The exact nature of the injury is still unclear, but he was moving relatively slowly when coming off the field. The severity should become known later once the team medical staff takes a look at him, but it likely won't affect the forgone conclusion that Young will start the 2018 season in the minors.

Rosario (groin) said Wednesday that "in a couple of days I will be back for sure," Anthony DiComo of MLB.com reports.

Tuesday's MRI came back negative, and the Mets will want to get their young shortstop back on the field as soon as possible to prepare for Opening Day. Rosario's eventual upside remains impressive as he learns to turn his athleticism into production, but for fantasy purposes the 22-year-old shouldn't be counted on as more than a stolen-base threat in his first full big-league campaign.

Diaz (ankle) will start at second base and bat seventh in Thursday's Grapefruit League game against the Cardinals, Clark Spencer of the Miami Herald reports.

Diaz isn't scheduled to play a full nine innings with Riley Mahan on track to replace him at some point mid-game, but Diaz's presence in the field a day after tweaking his left ankle in a collision suggests the Marlins aren't concerned about his health. One of four prospects the Marlins acquired in January in the trade that sent Christian Yelich to the Brewers, Diaz is expected to open the 2018 campaign at either High-A Jupiter or Double-A Jacksonville.

Herrera returned to action Wednesday after missing a few days with tightness in his shoulder and had three hits against the White Sox, the Dayton Daily News's Hal McCoy reports.

Previously the Reds suggested that the tightness that Herrera was dealing with was normal in the recovery process, and Wednesday's results seem to buttress that assertion. Herrera is trying to show that he can remain healthy enough to play and then play well enough to win a roster spot with the Reds.

Diaz left Wednesday's game against the Astros with an apparent left ankle injury, Craig Davis of the South Florida Sun Sentinel reports.

Diaz collided with Isaac Galloway while the pair chased a flyball. The young infielder exited the game limping. The seriousness of his injury is not yet clear.

The Mets revealed Wednesday that Rosario, who was previously diagnosed with left knee soreness, is instead nursing a sore groin, Tim Healey of Newsday reports.

Rosario underwent an MRI on the knee Tuesday that returned negative, and it appears the scans detected the true source of the shortstop's discomfort in the process. The Mets are labeling Rosario as day-to-day, so he doesn't look to be in any real danger of missing Opening Day at this time. That being said, the 22-year-old is missing out on meaningful at-bats during Grapefruit League play, which may result in the Mets restricting his workload more than they had originally intended once the regular season begins.

Rosario's MRI revealed no serious issues Tuesday, Matt Ehalt of The Bergen Record reports.

Rosario has been out for a few days with knee soreness, though the MRI was apparently on his groin and hamstring. His knee is reportedly feeling better. It seems as though he's dealing with multiple minor leg ailments, but apparently none are that serious.
