2022 Fantasy Outlook
Matz got lit up during the short 2020 season to the tune of 4.1 HR/9, leading to a 9.68 ERA. He regressed back to his previous results with an ERA near 4.00 last season while striking almost a batter per inning. It was almost a mirror image of his 2018 and 2019 campaigns. Most of Matz's struggles took place in his early-season "home" starts in Dunedin (5.23 ERA) and Buffalo (6.00). He went on to post a 2.12 ERA in Toronto. Now, he moves to an even bigger home park in St. Louis with one of the league's best defenses behind him. One item to keep an eye on is his fastball velocity. Before going on the COVID-IL in mid-June, he had a 9.4 K/9 with his fastball averaging 94.8 mph. After he returned from the injury (around the same time the foreign substance ban got enforced), those dropped to 7.7 K/9 and 94.1 mph. Matz has never been a consistent pitcher and it'll be interesting to see which version shows up in 2022. Read Past Outlooks

Earns win in return
PSt. Louis Cardinals
September 17, 2022
Matz (5-3) struck out one in a perfect inning to earn the win in the second game of Saturday's doubleheader versus the Reds.
ANALYSIS
Matz made his return from a torn left MCL in this appearance. He was immediately rewarded as the Cardinals won in the 11th inning after generating the lone run of the game on an error. This was Matz's first relief outing since 2020 with the Mets and just his sixth appearance out of the bullpen in his career. He has a 5.56 ERA, 1.28 WHIP and 52:9 K:BB through 43.2 innings this year, though it's expected he'll serve as a multi-inning reliever for the rest of the campaign.

When you look up the word enigma in the dictionary, you will find Matz's picture as an illustration of the word. For all of his potential, we have seen few results to back it up. This past season saw him strike out one of every four batters he faced, but that is the entire success story. Full stop. Matz was blasted around the strikeouts, allowing 14 homers in 30.2 innings of work. It was so bad, Jose Lima and Bert Blyleven felt bad for him. Add in 42 hits allowed and 10 walks, and it is pretty easy to figure out how a talented arm went 0-5 with a 9.68 ERA. The big blue wave of 2020 turned out to be Matz's Statcast page as he finished in the bottom 10th percentile in nearly every measure available. The Blue Jays bought low in an offseason trade, which may provide Matz the change of scenery he needs to right the ship. He should slot into the middle of Toronto's rotation.
Aside from a two-week stint on the injured list in May, Matz did well in his efforts to shed the "injury prone" label, making 30-plus starts for the second straight year while covering a career-high 160.1 innings. The improved health seemingly hasn't translated to much meaningful skills growth, however, as Matz's 4.23 xFIP and 14.5 K-BB% over the past two seasons are just about in line with his career marks (4.01 and 14.8%). Now 28 years old, Matz may never become the No. 2 starter that once seemed like a possibility when he broke into the majors in 2015, but he still maintains usefulness as a mid-rotation or back-end arm for both a real-life or fantasy pitching staff. Ideally, fantasy managers would maximize Matz's utility by keeping him active primarily for his home starts. He owns a 3.47 ERA at Citi Field for his career, including an exceptional 2.31 mark over 89.2 innings in 2019.
Matz exceeded the limited expectations set by his shaky health history, establishing career highs in starts and innings after offseason elbow surgery. The lefty kicked his K/9 back toward 9.0 and thrived in his home starts (3.59 ERA). Unfortunately, he endured another harmful HR/9 and posted a career-worst BB/9, leading the ERA estimators to paint a less rosy picture. The lefty dealt with a flexor pronator sprain in his left elbow in August but rebounded with a 2.51 ERA and 39 strikeouts in 32.1 September innings. In the end, he had a 10.4 K/9 in the second half. Matz worked to establish a repeatable delivery, and if the 26-year-old can build on his velocity gains and limit damage from right-handed batters (1.66 HR/9), his true breakthrough could still happen. You shouldn't have to pay for another 30 starts, which helps Matz's appeal.
After having bone spurs removed from his elbow prior to the 2017 campaign, Matz opened the season on the disabled list with renewed elbow discomfort. He came off the DL at the beginning of June and pitched 13 games before undergoing season-ending surgery to correct a nerve issue, again in his elbow. While active, Matz changed his approach in an effort to preserve his health. During the 2016 season, Matz threw his slider 10.4 percent of the time. That figure fell to 4.3 percent in 2017 -- he ditched the offering completely for a while. The change harmed his performance and resulted in a 6.08 ERA and 1.53 WHIP, career-worsts for the 26-year-old lefty. The long ball was detrimental to Matz, who gave up home runs at an alarming rate of 1.63 HR/9. Matz is expected to be ready for spring training and should have a rotation spot, but he is about as high risk of an arm as there is in baseball.
Unfortunately, nothing about Matz's outlook changed in 2016. He was seen as a high-end No. 3 starter with durability concerns, and sure enough, he posted a 3.39 FIP and 129:31 K:BB in 132.1 innings but missed the final six weeks of the season with a shoulder injury. He did not need shoulder surgery, but he did have an offseason procedure to remove a bone spur from his elbow, further adding to the litany of arm issues on his resume at the age of 25. At his best, Matz pairs a mid-90s sinker that can miss bats with above-average secondaries in his curveball and changeup. His 51.1 percent groundball rate ranked 18th among starters with 130-plus innings, and for a sinkerballer, his 23.6 percent strikeout rate is pretty impressive. Matz will enter spring training as the Mets' No. 4 starter, and he will be appropriately discounted in drafts due to the durability concerns. If he ever stays healthy for a full season, his owners will enjoy the profits.
Already flush with an obscene amount of pitching, the Mets called up Matz in late June and he appeared ready to join the conversation as the next big thing along with his young rotation-mates. His first two starts were 13.2 IP of a 1.32 ERA and 0.88 WHIP with 14 strikeouts and five walks. A torn lat muscle halted his speedy ascent and cost him two months, but he was good in September and throughout the postseason with a 3.19 ERA across 36.2 IP. The skills aren’t really in question, even after just 50 IP (regular & postseason), but health was an issue coming up through the minors and seeing him hit the DL after just two MLB starts is worrisome. At the same time, this kind of profile can net big returns as long as the price isn’t through the roof. Betting on health when the skills are already in place is a worthy gamble and a better use of resources than hoping for skills growth in areas of weakness.
Tommy John surgery prevented Matz, a 2009 second-rounder, from debuting as a pro until 2012. He wouldn’t make his full season debut until a year later, and while the numbers were impressive, he was as a 22-year-old in A-ball. Matz took a big step forward in 2014, not only with another injury-free season during which he managed a career-high innings total (141), but he dominated yet again, splitting time between High-A and Double-A with a low-2.00s ERA in both. He works at 92-94 mph from the left side with solid command. His slow curve can be a plus pitch and should also miss bats regularly. The growth of his changeup will determine his future. When right, it looks great, but it is inconsistent. He has made up for the missed time and now sits on the doorstep of the big leagues, but the Mets may not have a need anytime soon. Consider Matz a worthwhile pick in leagues with minor league focus, otherwise wait until he is in the majors to act on him.
Matz, the Mets' top selection in the 2009 draft, had a slow recovery from May 2010 Tommy John surgery, finally pitching this year in the minors. He made the most of the year, tossing an impressive season for Low-A Savannah and posting a 2.62 ERA with 121 strikeouts over 106.1 innings. He has a fastball that tops out around 94 mph in addition to a good feel for his curveball and changeup. Matz was added to the 40-man roster in November to protect him from the Rule 5 draft, and he should begin 2014 at High-A St. Lucie.
