New York Mets starting pitcher Sean Manaea has been refining his pitch arsenal during spring training. The 32-year-old lefty spent the 2021 and 2022 off-seasons at Driveline Baseball in Kent, WA to work on his velocity and pitch mix. The hard work during the offseason paid off as he put together a solid 4.44 ERA (3.90 FIP), 1.241 WHIP, and 128:42 K/BB ratio over 117 2/3 innings (37 appearances, 10 starts) with the San Francisco Giants. His sweeper and changeup were two of his best pitches last season and he's added a cutter to his arsenal as well. The Mets plan to have Manaea start the year in their rotation so their plan during spring training is to optimize and refine his pitches to give him a solid plan on how to deploy them all against batters. Given his recent resurgence, Manaea is worth a dart throw late in fantasy drafts this spring.

Miami Marlins relief pitcher Tanner Scott won his arbitration case over the Miami Marlins, according to Mark Feinsand of MLB Network. There was a $550,000 delta between the two sides, with Miami wanting to pay Scott $5.15 million, and the closer wanting $5.7 million. The 29-year-old will be a free agent after this season and is certainly worth the salary he will make given what he provided last year for Miami. He compiled a 2.31 ERA, 0.99 WHIP, and 104:24 K/BB over 78 innings to go along with 12 saves. He should open the year as the Marlins' closer and is therefore worth securing in upcoming fantasy drafts.

Miami Marlins starting pitcher Trevor Rogers (lat, biceps) is healthy as spring training gets underway. The 26-year-old lefty was limited to just four starts and 18 innings last season due to lat and biceps injuries. He compiled a 4.00 ERA during those four starts, but he was coming off a disastrous 2022 season in which he put up a 5.47 ERA, 1.505 WHIP, and 106:45 K/BB over 107 innings (23 starts). Rogers was the runner-up for the National League Rookie of the Year back in 2021. His fastball sits in the mid-90s, and he can induce a lot of whiffs with both his slider and changeup. Miami manager Skip Schumaker told reporters that he expects Rogers to be a big part of the team's rotation that will be without ace Sandy Alcantara (elbow), who underwent elbow surgery back in October. Rogers is an interesting post-hype sleeper name in fantasy due to his past success. He could be a steal late in drafts if he can stay healthy and regain his rookie form.

Miami Marlins pitcher A.J. Puk is being stretched out as a starter as spring training gets underway. The lanky reliever has only worked out of the bullpen in the majors but was primarily a starter back in his college days at the University of Florida. He's yet to make a single start through his first 142 major league outings, according to beat writer Christina De Nicola. However, the Marlins currently have an open rotation spot and with Puk's past experience as a starter, this makes sense. In addition to Puk, Miami is also stretching out Ryan Weathers, George Soriano, and Max Meyer. Injuries have plagued Puk in the early part of his career but he's maintained relative health over the last few seasons, compiling a 3.50 ERA, 1.163 WHIP, and 154:36 K/BB ratio to go along with 19 saves over 123 innings of relief between Oakland and Miami. He's an interesting name to keep an eye on considering his past prospect pedigree. There's no guarantee he opens the year in the starting rotation but he should hold fantasy value whether he starts or comes out of the pen for the Fish.

Free-agent right-hander Chase Anderson agreed with the Pittsburgh Pirates on Saturday on a minor-league deal that includes an invitation to major-league spring training, according to a source. Anderson will be in camp with the Bucs this year looking to win a roster spot for the start of the 2024 regular season. The 36-year-old veteran hasn't been very reliable in 10 major-league seasons and went a combined 1-6 with a 5.42 ERA (5.72 FIP), a 1.42 WHIP, his first career save, 33 walks and 64 strikeouts in 86 1/3 innings over 19 appearances (17 starts) for the Tampa Bay Rays and Colorado Rockies a season ago. Even if he makes Pittsburgh's Opening Day roster, Anderson isn't really going to be much of a fantasy weapon. He's posted a career ERA of 4.35 with a 1.29 WHIP and a well below-average 19.9 percent strikeout rate in 1,049 MLB innings.
