Matt Roberts/Getty ImagesAs we begin the final weekend of the 2018 MLB regular season http://www.padresfanproshop.com/authentic-trevor-hoffman-jersey , the vast majority of teams have already turned their attention to 2019, and their respective fanbases are no doubt doing the same.For teams not headed to the postseason, work has no doubt already begun on assessing this year's crop of free agents.Superstars Bryce Harper and Manny Machado are the headliners of the class and could be headed for record deals thanks to their age an impressive track records to date.However, the class by no means begins and ends with that duo, as there's a wealth of potential game-changing talent set to hit the open market.We've rounded up some of the latest rumors surrounding a few of the top names who could be on the move this winter.Matt Harvey Won't Return to the New York MetsAndy Lyons/Getty ImagesWhen asked about the possibility of returning to the Cincinnati Reds in free agency recently, Matt Harvey offered up the following to Mark Sheldon of MLB.com:"Absolutely. There's only one team out there I would not sign with. That's about it."It's not hard to piece that one together.Once a budding superstar for the New York Mets, Harvey's decline was a drastic one as injuries derailed his career.After struggling to a 6.70 ERA over 92.2 innings in 2017, he was quickly demoted to the bullpen this season after a similarly rocky start and eventually traded to the Reds in exchange for catcher Devin Mesoraco.While he hasn't regained his previously elite form, he has been a serviceable starter since the trade, going 7-7 with a 4.50 ERA (4.33 FIP) and 1.25 WHIP with 111 strikeouts in 128 innings.Now he'll hit the open market for the first time, and while he's not on the same level as top-tier options like Clayton Kershaw, Patrick Corbin, Dallas Keuchel and Charlie Morton, he's an intriguing buy-low option.He just won't be an option for the Mets.Prediction:Harvey re-signs with the Reds on a two-year, $15 million deal.International Star Victor Victor Mesa to Host a ShowcaseMatt Roberts/Getty ImagesWhile he won't drum up the same offseason frenzy that Shohei Ohtani created last offseason prior to signing with the Los Angeles Angels, Cuban outfielder Victor Victor Mesa has a chance to be an impact player in his own right.He'll be joined in the showcase by his 16-year-old brother Victor Mesa Jr. and hard-throwing right-hander Sandy Gaston.Jesse Sanchez JesseSanchezMLBBREAKING: The Mesa showcase will be stateside.International prospects Victor Victor Mesa and Victor Mesa Jr. will work out for all 30 teams on 10/5 at Marlins Park. RHP Sandy Gaston Evan Longoria Jersey , who is also from Cuba, will also work out for teams. ldbzADPY62The older Mesa is considered by most to be the top international talent available this offseason.During his last full season playing in the Cuban National Series in 2016-17, he hit .354/.399/.539 with 40 steals in 70 games.Ben Badler ofBaseball Americaoffered up the following scouting report back in May:"Mesa,21,is a comparable player to Nationals center fielderVictor Robles,theNo. 5prospectonBaseball America's Top 100 Prospects list. He's a premium defender in center fieldwho at his best has shown70 speed and at least a70 arm on the 20-80 scale.He getsquick reads off the bat and takes sharp routes to cover plenty of ground in center field and make highlight-reel catches, winning a gold glove award in Cuba when he was 17."The Orioles ($6.5 million), Marlins ($4.3 million), Rays ($3.6 million) and Dodgers ($2.78 million) have the most remaining bonus poll money to spend, according to Jesse Sanchez of MLB.com.With the O's making a newfound commitment to international scouting and the Marlins having a strong tie to the Cuban community, those two look like the favorites.Prediction: Victor VictorMesa signs with the Marlins.Former All-Star Closer Trevor Rosenthal to Hold WorkoutJeff Curry/Getty ImagesA few days before the Mesa brothers show off their talents to a hoard of MLB scouts, right-hander Trevor Rosenthal will hold a showcase of his own.Trevor Rosenthal TrevRosenthalI鈥檒l be doing a workout for teams next Wednesday, October 3rd. 11am UC Irvine in Irvine, CA. Looking forward to this and the 2019 season.The 28-year-old has been working his way back from Tommy John surgery all season, and he's posted a few video clips of himself on the comeback trail.Trevor Rosenthal TrevRosenthalI鈥檒l be doing a workout for teams in early October. I鈥檒l post the details as we get closer. Everything has gone so well this year. I鈥檓 anxious to see what the future holds! SesB7mNl25Rosenthal was at his best in 2015, when he nailed down 48 of 51 save chances with a 2.10 ERA Andrew McCutchen Jersey , 1.27 WHIP and 10.9 K/9 to earn his lone All-Star appearance and finish 17th in NL MVP voting.After a rocky 2016 season, he rebounded nicely in 2017 with a 3.40 ERA and 14.3 K/9 in 50 appearances, as he eventually moved back into the closer's role after starting the season in a setup capacity.However, the elbow injury that eventually required surgery cut his season short and spelled an end to his time in St. Louis, as he was non-tendered last offseason.He has a chance to be a great under-the-radar signing for a team looking for late-inning help but not looking to break the bank with a run at Craig Kimbrel or Andrew Miller.Prediction:Rosenthal signs with the Braves on a one-year, $5 million deal that includes a mutual option for 2020.All stats courtesy of Baseball Referenceand accurate through Sept. 27. NEW YORK (AP) — Aiming for an instant upgrade after two failing seasons, the New York Mets and their rookie general manager turned to a most familiar face.The Mets made a splash — that much was certain — when they acquired eight-time All-Star second baseman Robinson Cano and major league saves leader Edwin Diaz from the Seattle Mariners in a seven-player trade Monday.In his first big move as Mets GM, Brodie Van Wagenen brought the 36-year-old Cano back to New York. Van Wagenen previously was an agent and represented the former Yankees slugger.The rebuilding Mariners also sent $20 million to the Mets for outfielder Jay Bruce, reliever Anthony Swarzak and three prospects: former first-round draft picks Justin Dunn and Jarred Kelenic, plus right-hander Gerson Bautista.Mets fans were strongly split on the deal.Some applauded the trade as a chance for a team three years removed from the World Series to quickly head back in that direction. The Mets went 77-85 this year despite a rotation that included NL Cy Young Award winner Jacob deGrom, Noah Syndergaard and Zack Wheeler.Others saw the Mets mortgaging their future for a high-priced player on the back end of his career. Many Mets rooters remembered deals for aging second basemen Carlos Baerga and Roberto Alomar Jr. that didn’t work out — it was also mentioned that on this date, Dec. 3, back in 1969, the Mets traded soon-to-be star center fielder Amos Otis to Kansas City for washout third baseman Joe Foy.Van Wagenen, Cano and Diaz were set to talk about the deal Tuesday during a holiday party at Citi Field.Cano is halfway through a $240 million, 10-year contract. With the cash from Seattle http://www.giantsfanproshop.com/authentic-tony-watson-jersey , the Mets will be responsible for $100 million of the $120 million owed to Cano.Cano served an 80-game suspension this year following a positive test for Furosemide, a diuretic that can be used to mask performance-enhancing drugs. Cano claimed the Furosemide was given to him by a licensed doctor in the Dominican Republic. The suspension was announced May 15, two days after Cano’s right hand was broken when he was hit by a pitch thrown by Detroit’s Blaine Hardy.Cano returned to the Mariners on Aug. 14 and finished with a .303 batting average, 10 homers and 50 RBIs in 80 games. He waived his no-trade clause to return to New York.Van Wagenen was co-head of CAA Baseball before joining the Mets in October and negotiated Cano’s contract with Seattle in December 2013. Cano has a .304 career batting average with 311 homers and 1,233 RBIs, including four 100-RBI seasons. He has a career .848 OPS, including an .845 mark last season.Diaz’s value may never have been higher after the hard-throwing 24-year-old topped the majors with 57 saves last season. The Mets needed a closer after trading Jeurys Familia to Oakland last July.The Mariners are completely revamping their roster this offseason, having already traded ace James Paxton to the Yankees. Seattle also traded All-Star shortstop Jean Segura and pitchers James Pazos and Juan Nicasio to Philadelphia on Monday for veteran slugger Carlos Santana and young infielder J.P. Crawford.“This trade bolsters our player development system with the additions of Jarred Kelenic and Justin Dunn, while also providing immediate impact to our major league club,” Mariners GM Jerry Dipoto said in a statement.Diaz had a 1.96 ERA and struck out 124 in 73 1/3 innings.Seattle has not reached the playoffs since 2001, the longest postseason drought across the four major pro American sports. After finishing third in the AL West despite an 89-73 record, the Mariners decided to go in another direction.Bruce, a three-time All-Star with Cincinnati who is 31, was acquired by the Mets at the 2016 trade deadline, dealt to Cleveland in August 2017, became a free agent and returned to the Mets last January. He hit .223 this year and set career lows with nine homers and 37 RBIs Gregor Blanco Jersey , sidelined from June 18 through Aug. 24 by a right hip issue.Swarzak, 33, was 0-2 with a 6.15 ERA in 29 relief appearances. He was on the disabled list twice, from April 1 through June 4 due to a strained left oblique and from Aug. 4 through Sept. 8 with right shoulder inflammation.Bruce is owed $13 million in each of the next two seasons, and Swarzak is due $9 million in the final season of his two-year deal.Kelenic, a 19-year-old outfielder, was the sixth overall selection this year and hit .286 with six homers, 42 RBIs and 15 steals in 56 games of rookie ball. Dunn, a 23-year-old right-hander, was the 19th overall pick in 2016 and was 8-8 with a 3.59 ERA this year over 24 starts at Class A and Double-A.MLB.com slotted Kelenic as the No. 2 prospect in Seattle’s system and Dunn at No. 3. They’re behind left-hander Justus Sheffield, who was acquired from the Yankees last month for Paxton.Bautista, a 23-year-old right-hander, made his big league debut with the Mets last April and had a 12.46 ERA in five big league appearances. He was 4-1 with a 5.14 ERA in 37 games at Double-A and Triple-A, striking out 69 in 49 innings.Seattle will pay $5 million to the Mets this Dec. 21 and $3.75 million on each Dec. 1 from 2019-22.
