Steven Matz is unlikely to be ready for Opening Day because of tenderness in his left elbow, the New York Mets have announced.

"He's being examined today," Collins said Wednesday. "We should know more, but we don't plan on having him pitch the next few days."

Matz is expected to have an MRI. The left-hander threw on the side on Monday and Tuesday and was still feeling pain.

"Nothing's changed over the last couple of days," Collins said. "It's just that the last two days he played catch, and he still feels it, so we thought it would be important to have him looked at."

Matz was projected to be New York's No. 5 starter.

The Boston Red Sox scratched Tyler Thornburg from a scheduled appearance Monday against the Baltimore Orioles because of a spasm in his upper right trapezius.

Thornburg hasn't pitched in a Major League spring training game since March 1 because of weakness in his right shoulder. He "most likely" will open the season on the disabled list.

He is expected to undergo testing, including a possible MRI exam.

"If it's what I anticipate, probably not," Dave Dombrowski said. "But I can't rule anything out because I don't really know anything (other) than what we just found out, that he's got a trap that's tight. If it's a short-term situation, then I don't have a spot to offer somebody."

Royals outfielder Jorge Soler will likely begin his first season in Kansas City on the disabled list after straining his oblique in a minor league game.

Marlins pitcher Jeff Locke is likely to miss at least the first month of the season as he recovers from biceps tendinitis, according to manager Don Mattingly.

Locke threw off a mound Saturday morning for the first time in more than a month, showing progress from an injury suffered at the start of spring training.

"I don't know what we'll do next, but for today it was good," Locke told reporters of the session, according to the South Florida Sun Sentinel. "I feel a lot better than I was feeling before, that's for sure."

The White Sox scratched Carlos Rodon from his spring start Friday due to left biceps tightness, and general manager Rick Hahn said the left-hander likely would begin the season on the disabled list.

Rodon also had an MRI that showed no structural damage. He will get a second opinion next week.

Giants reliever Will Smith said Friday he will have Tommy John surgery next week, meaning he will miss the 2017 season.

Tigers outfielder J.D. Martinez will miss three to four weeks because of a sprained Lisfranc ligament in his right foot, manager Brad Ausmus announced Friday.

Drew Pomeranz left his exhibition start one inning earlier than expected on Sunday due to left triceps tightness.

Pomeranz first developed the tightness in the first inning against the Minnesota Twins and it persisted into the second frame. He threw 47 pitches and didn't come out for a third scheduled inning.

The left-hander told reporters he didn't think the injury was serious, but the Boston Red Sox will be careful. Pomeranz experienced left elbow/forearm stiffness late last season and received a stem-cell injection over the winter.

There are also injury concerns surrounding David Price entering the season.

Indians second baseman Jason Kipnis is still four to five weeks away from playing in a game as he deals with shoulder inflammation, adding to the team's injury woes.

Kipnis received a second opinion on his shoulder and has been cleared to resume a strengthening program in a week.

Meanwhile, Indians right-hander Cody Anderson will undergo reconstructive elbow surgery and miss the 2017 season.

Tigers outfielder J.D. Martinez suffered a right midfoot sprain in Saturday's spring training game against the Marlins, the team announced.

The Tigers said Martinez was taken for X-rays, which came back negative, and will be re-evaluated Sunday.

"We'll see about it tomorrow," Martinez told reporters, according to MLB.com. "I know as much about it as you guys do. It's good that I'm able to move on it."
