Matz has suffered a partially torn left lat muscle, and will miss at least three weeks, Mike Vorkunov of The Star-Ledger reports. The Mets are now officially confirming the injury, and the 25-year-old hurler has already received a PRP injection. He won't be able to start throwing for three weeks, at which point he will be re-examined. He's likely more than a month from a return, so the Mets will likely return to a five-man rotation. Either Bartolo Colon or Jon Niese are expected to start in his place Saturday.

Matz is expected to miss "at least several weeks" with a lat injury, Andy Martino of the New York Daily News reports. The Mets have not confirmed that Matz will miss time -- he's still listed as Sunday's probable starter on the team's official site -- but it sounds like a DL stint is a real possibility. If the lefty does wind up on the DL, look for New York to move back to a traditional five-man rotation coming out of the break. Matz acknowledged that he felt some tightness in his lat muscle in his big-league debut, but said that it didn't notice it in his last outing.

Matz said he felt some tightness in his left lat/arm during his first start, but he didn't notice it during Sunday's game against the Dodgers, Newsday's Marc Carig reports. The tightness apparently wasn't much of an issue, as Matz was brilliant in the second start of his career, striking out eight batters over six scoreless innings, with just two hits and two walks allowed. He even added another RBI, though he couldn't match last weekend's heroic 3-for-3, 4-RBI effort at the plate. The lat tightness is worth keeping an eye on, but Matz should be fine to make his final start before the All-Star break, scheduled for Sunday against the Diamondbacks at Citi Field.

Matz had a major-league debut to remember Sunday, giving up two runs on five hits and striking out six in 7.2 innings to get the win. At the plate, he went 3-for-3 with four RBI, a feat no other pitcher has ever done in his MLB debut in the last 100 years. Matz picked up a tired bullpen, who went seven innings earlier Sunday, in the completion of Saturday's suspended game. He threw 110 pitches, his most of the season. Matz was 7-for-23 at the plate in Triple-A but no one could have imagined him being that good of a hitter Sunday. With the Mets using a six-man rotation, Matz's next start will come against LA next weekend.

Matz was formally recalled from Triple-A Las Vegas on Sunday, MLB.com reports. As was reported Friday, Matz will make his MLB debut Sunday against the Reds following a dazzling showing at Triple-A this season. The 23-year-old has compiled a 2.19 ERA, 1.10 WHIP, and 94:31 K:BB ratio over 90.1 innings at one of the Pacific Coast League's harsher environments, creating plenty of optimism about his chances of finding success right away in the majors. Matz will have a good shot at capturing the win in his first start, as the Reds will counter with long-time minor-league journeyman Josh Smith, who was tacked for four runs in three innings in his big-league debut last Tuesday.

Matz will get the start for the Mets on Sunday for his major league debut, Adam Rubin of ESPN New York reports. Matz has been dominant at Triple-A this season with a 2.19 ERA and 94 strikeouts in 90.1 innings of work. The lefty prospect will join a very talented and young rotation that also features the likes of Matt Harvey, Jacob deGrom, and Noah Syndergaard. Matz should stick with the big league club for the time being as the Mets are reverting to a six-man rotation.

Matz is expected to be called up to start Sunday against the Reds, Newsday's Marc Carig reports. Ken Rosenthal of FOX Sports had the initial report, and while the Mets still have yet to confirm, sources tell Newsday that Matz will indeed come up for his major league debut Sunday. Simply put, Matz has nothing left to prove at Triple-A, having posted a 2.19 ERA, 1.11 WHIP and 94:31 K:BB in 90.1 innings with Las Vegas to begin the year. It sounds like he will get an extended run with the big club, as the Mets are reportedly moving back to a six-man rotation.

The Mets appear to be on the verge of recalling Matz from Triple-A Las Vegas, Ken Rosenthal of Fox Sports reports. The Mets haven't confirmed anything of the sort, and the rumors have been going around for awhile, but this time something appears to be materializing. Matz has pitched extremely well at Triple-A Las Vegas, posting a 2.19 ERA and 1.11 WHIP with 94 strikeouts over 90.1 innings this season. The club would have to make a corresponding move to add him, but there's been talks of a potential trade that could open up a spot.

Mats threw seven shutout innings, allowing just four hits while walking one and striking out five Wedensday. Matz rebounded from a rough outing to have what has become for him a normal day in the office. With Dillon Gee designated for assignment, the path for Matz to get called up got a bit clearer and easier. The expectation is that his first game in the majors will come sometime before the All-Star break.

The Mets have recently discussed moving Noah Syndergaard to the bullpen and calling up Matz, Mike Puma of the NY Post reports. Syndergaard would be used to set up Jeurys Familia while Matz would slide into Syndergaard's rotation spot. The Mets have struggled to find a bridge to Familia and Syndergaard's high-90s fastball and 'hook from hell,' could fill that spot. This is from a done deal, as both Syndergaard and Matz profile starting pitchers, so view this as an outside possibility for the time being.
