MLB Player News

Diaz left Tuesday's game against the Rockies with an apparent leg injury, Josh Tolentino of The Athletic reports.

Diaz hit a double during the eighth inning and limped into second base, but he may have actually sustained the injury earlier in the game. Ji-Man Choi entered as a pinch runner and should remain in the game at first base, while the specifics of Diaz's injury are currently unclear.

Olson (hand) had his soft cast and stitches removed and said he feels good Tuesday, Susan Slusser of the San Francisco Chronicle reports.

He was in good spirits, apparently firing up shots with a nerf basketball in the clubhouse using his surgically repaired right hand. Per the original timetable, Olson is roughly 5-to-7 weeks away from resuming normal activity -- it is largely a matter of pain tolerance.

Alonso sits for the first time this season Tuesday against the Marlins, Tim Healey of Newsday reports.

Alonso certainly hasn't done anything to suggest he should be removed from the lineup through his first four games, going 7-for-17 at the plate with three doubles and a homer. The Mets may simply want to keep Dominic Smith fresh.

Diaz went 1-for-2 with two walks and two runs in a win over the Rockies on Monday.

Diaz has opened the season with a five-game hitting streak, a stretch during which he's flashed various aspects of his diverse offensive profile. The 27-year-old has logged a pair of doubles, a home run and three walks, and he's complemented it with just a single strikeout over his first 20 plate appearances. With an everyday job locked in and solid upside, Diaz's value should remain robust across all formats as the season unfolds.

Walker went 2-for-4 with a walk, a double and a run scored in Monday's 10-3 win over the Padres.

Walker has come out of the gate hitting, going 6-for-11 with two home runs and two doubles in four games, presenting a challenge for manger Torey Lovullo: how to get both starting first baseman Jake Lamb and Walker, his backup, in the lineup at the same time. Lovullo began setting the stage Monday. Before Walker mashed another left-hander, Lamb took groundballs at third base during batting practice Monday, Nick Piecoro of the Arizona Republic reports. By having Lamb get comfortable at the hot corner, his old position, Lovullo is establishing a path forward to get Walker more playing time while keeping Lamb's bat in the lineup.

Alonso went 1-for-5 with a three-run homer in Monday's 7-3 win over Miami.

Alonso's home run, the first of his career, gave the Mets a four-run cushion after entering the ninth inning all tied up at 3-3. The highly-touted prospect is 7-for-17 with four extra-base hits to start his MLB career. He's absolutely worth a roster spot in all fantasy leagues right now.

Smith will draw the start at first base Tuesday against the Marlins, Mike Puma of the New York Post reports.

Smith is 1-for-3 with two RBI, a walk and a run scored through the first three games of the season, and manager Mickey Callaway will elect to insert Smith's left-handed bat into the starting lineup with Jose Urena (knee) slated to toe the rubber for the opposition. Pete Alonso will likely take a seat as a result.

Manager Don Mattingly said Cooper underwent an MRI that revealed a mild left calf strain, Andre Fernandez of The Athletic reports.

Cooper suffered the injury over the weekend and was sent to the IL as a result. The 28-year-old said he isn't expected to resume baseball activities for a few weeks, suggesting his stay on the shelf could last more than a month. Peter O'Brien, who has started in right field each of the past two games, looks poised to fill in for Cooper for the time being.

Guerrera (oblique) has been taking at-bats in extended spring training games and looks good, Ben Nicholson-Smith of Sportsnet.ca reports.

Guerrero is working his way back from an oblique strain, but it doesn't appear as though he'll miss much time. He's expected to spend a couple weeks in the minors as the Blue Jays wait to promote him until they secure an extra year of team control.

Arias will begin the 2019 season at High-A Lake Elsinore, Jeff Sanders of The San Diego Union-Tribune reports.

Arias will advance another rung on the minor-league ladder after playing exclusively at Low-A Fort Wayne in 2018. While Arias' .654 OPS and 29.6 percent strikeout rate over 504 plate appearances wasn't anything to write home about, his numbers were far more impressive after considering that he was the youngest full-time player in the Midwest League.
