Red Sox's offer to Martinez reportedly $125 million
The Red Sox's much-discussed interest in free-agent slugger J.D. Martinez reached a new level on Friday with a report from the Boston Herald that the club has made Martinez an offer of five years and approximately $125 million. The club hasn't confirmed the report.
It had been reported recently that the Red Sox had extended an offer to Martinez of five years and about $100 million.
Martinez's agent, Scott Boras, told MLB Network insider Jon Heyman that the reports of the first offer, which was said to be less than what Martinez was seeking, were "not accurate." Heyman reported last week that Martinez is looking for a six-year deal valued at $30 million per year. Boston has been seen as the favorite to land Martinez.
Heyman reported last week that Martinez is willing to hold out until Spring Training for a contract that he believes meets his market value, which indicates other clubs are also involved in negotiations. Martinez was a catalyst for the D-backs last year in helping them reach the postseason for the first time since 2011, and Arizona is reportedly still interested in bringing him back, per Heyman.
Martinez hit 29 homers with 65 RBIs in just 62 games for the D-backs after being acquired on July 18, trailing only National League MVP Giancarlo Stanton in each category during that span. Martinez hit 45 homers during the 2017 season, despite playing in just 119 games. He became the first player in MLB history with that many home runs in so few games.
If the Red Sox do indeed sign Martinez, that would create a dilemma in the outfield. Martinez would reportedly prefer to play outfield, but Boston already has Gold Glove Award winner Mookie Betts, along with Jackie Bradley Jr. and Andrew Benintendi. That means Martinez would likely be the club's designated hitter, which in turn may give Arizona an edge, in addition to the fact that the club recently hired Martinez's personal hitting coach.
Yankees, Rangers, Marlins favorites for Cuban prospect Martinez
Twenty-one-year-old Cuban outfield prospect Julio Pablo Martinez is still waiting to be cleared by Major League Baseball to sign, but three teams have emerged as favorites to sign him if and when he becomes eligible.
The Marlins, Rangers and Yankees have separated themselves as favorites to sign Martinez, who is among the top young players from Cuba, sources tell MLB.com and as was first reported by Baseball America. Because of his age, Martinez will be subject to international bonus pool rules.
Martinez's talent is on par with a first-round Draft pick and that he would likely be ready for a Class A Advanced or Double-A assignment. At 5-foot-10, 185 pounds, the left-handed hitter has a promising combination of speed, power and athleticism that should allow him to stick in center field.
Martinez slashed .333/.469/.498 with six home runs and 24 stolen bases last season in the Cuban Serie Nacional while walking 52 times compared to 30 strikeouts. He also competed in the Canadian-American Association in 2017 and posted a .297/.345/.449 line with seven home runs and 20 stolen bases.
Martinez is likely to be cleared by Major League Baseball before the current signing period ends on June 15, but depending on which team he chooses, he could opt to sign in either the 2017-18 or 2018-19 period.
Because the Marlins and Yankees -- both of whom have held private workouts for him this week in Florida -- have limited bonus pool space left, Martinez would likely wait until July 2 to sign with either team. The Rangers, however, have significant international money left after failing to sign Japanese two-way star Shohei Ohtani and would likely choose to sign him in the current period.
Nunez works out for Red Sox
Free-agent utility infielder Eduardo Nunez recently worked out for the Red Sox in the Dominican Republic, according to the Boston Herald. Nunez spent part of last season with Boston, slashing .321/.353/.539 with eight home runs in 38 games following a trade from the Giants.
Nunez injured his right knee on Sept. 9, and though he tried twice to return -- once in the American League Division Series against the Astros -- he ended up aggravating the injury. According to the Herald report, doctors have declared the knee fully healthy, and Nunez's market is gaining steam, as he has been in contact with at least eight clubs.
If the Red Sox were to sign Nunez, they'd likely play him at second base to start the season, with veteran Dustin Pedroia recovering from knee surgery.
Per MLB Network insider Jon Heyman, the Mets are also showing serious interest in signing Nunez, particularly with their own need at second base.
Reynolds wants to return to Rockies on Major League deal
Free-agent first baseman Mark Reynolds would like to return to the Rockies, but not on a Minor League deal like he signed prior to the 2017 season, according to the Denver Post.
The 34-year-old Reynolds slashed .267/.352/.487 with 30 home runs in 148 games for Colorado in 2017, providing a lift when Ian Desmond, whom the club signed to a five-year, $70 million contract to play first base, was injured to open the season.
Despite slumping in the second half (.762 OPS with 11 homers), Reynolds produced a 105 OPS+ overall, his best since 2012. He did have stark home-road splits, however, slashing .294/.393/.584 at Coors Field, and .242/.311/.392 away from Denver.
When the Rockies signed Reynolds to a Minor League deal last February, he was coming off an injury-shortened season in which he posted an .806 OPS with 14 homers in 118 games for Colorado.
"I think I proved last year that I can produce and help a team," Reynolds told the Post. "I am looking to sign a Major League deal. ... Things are different this year."
The Rockies could use a first baseman, with Ryan McMahon waiting in the wings. Signing Reynolds could open the possibility of a platoon between him and McMahon, especially given that the 148 games Reynolds played in last season were his most since 2011.

Marlins want Acuna in a Yelich deal with Braves
Christian Yelich's name has been in the trade rumor mill for much of the offseason, and the buzz has picked up again after the center fielder's agent said Tuesday that Yelich hopes to be traded before Spring Training starts. According to MLB Network insider Peter Gammons, any deal would have to bring a "huge return" for Miami.
Citing conversations with teams that have called the Marlins about Yelich, Gammons said Wednesday on MLB Tonight that the Marlins won't move the 26-year-old unless they get back "star-level talent." As one example, Gammons said Miami has told the Braves that uber-prospect Ronald Acuna would have to be included in any trade for Yelich.
"The Marlins told the Braves, 'Look, we'll do a three- or four- or five-for-one, but Ronald Acuna has to be in it or we don't go even to the second player,'" Gammons said on MLB Network.
Acuna is one of baseball's very top prospects. He currently ranks as MLB's No. 6 overall prospect, according to MLB Pipeline, and could move up even further on that list in the upcoming 2018 rankings. The 20-year-old outfielder seems likely to be promoted to the big league club early next season.
Gammons said Acuna is a player the Braves won't trade, and the fact that the Marlins would tell the Braves that he would have to be the minimum headliner of any Yelich deal indicates that they're "shooting very high."
Following Miami's trades of Giancarlo Stanton, Marcell Ozuna and Dee Gordon to the Yankees, Cardinals and Mariners, respectively, Yelich and catcher J.T. Realmuto have been floated as the next players the team could potentially move as part of its rebuilding effort.
Gammons also mentioned Realmuto in the segment, saying that other teams' general managers think the Marlins might wait to trade Realmuto closer to the 2018 Trade Deadline.

Castellanos on the trade block?
While the Tigers were ultimately able to avoid an arbitration hearing with Nicholas Castellanos, Anthony Fenech of the Detroit Free Press reports that Detroit remains open to trading the rising slugger, citing multiple clubs that have engaged in discussions with the Tigers this offseason.

Castellanos, 25, agreed to a one-year, $6.05 million contract with the Tigers on Friday. Detroit's first-round Draft choice from 2010 is about to embark on his first full season in right field, but Fenech reports that the Tigers' uncertainty about his defensive ability could still lead to a trade before Opening Day. Castellanos has primarily manned third base during his first four full seasons in the Motor City, but he has rated below average in terms of Defensive Runs Saved (DRS) in each of those campaigns. He played 21 games in right last season.
Castellanos' prowess at the plate is much less in doubt. He broke out for a career-high 26 home runs and 101 RBIs for the Tigers in 2017 while recording a league-adjusted 110 OPS+ (where 100 is average) and pacing the American League with 10 triples. He was even more productive in some respects in '16, finishing with a 120 OPS+ over 110 games. While Castellanos will be eligible for arbitration again next winter, he will not test the free-agent market until 2020. That means Castellanos, for the moment, represents a controllable, relatively cheap hitter coming into his own -- regardless of his defensive ability.
Tigers general manager Al Avila revealed at the Winter Meetings that the team approached Castellanos about a contract extension toward the end of last season, but that no progress has been made.
If Pirates aren't contending, J-Hay wants to be dealt
A day after Andrew McCutchen was traded to San Francisco, Josh Harrison effectively asked to be traded "if indeed the team does not expect to contend this year or next" in a statement released Tuesday to MLB Network insider Ken Rosenthal. Harrison, 30, is under contract for $10.25 million this year, with club options for 2019 ($10.5 million) and '20 ($11.5 million). More >
Giants still looking for OF upgrades
Fresh off acquiring Andrew McCutchen from the Pirates on Monday, the Giants are trying to add even more talent to their outfield, with the former National League Most Valuable Player being told that he'll play a corner spot with the team this season, according to ESPN's Buster Olney.
San Francisco's main desire is to upgrade defensively in center field, and sources tell ESPN's Jerry Crasnick that the Giants rank Jarrod Dyson as their most coveted option behind Lorenzo Cain. The club is also interested in Jon Jay and Cameron Maybin, according to Crasnick, but values Dyson's "speed, defensive metrics and stolen-base ability."
The Giants, after bringing in McCutchen via a trade with the Pirates, do not have the space under the luxury-tax threshold to sign Cain at his projected salary, according to MLB.com's Jon Paul Morosi. Morosi reported that the club is looking to add a "defense-first player" in center field "who will be less expensive than Cain."
Dyson, Jay and Maybin will certainly all be less expensive than the former Royals center fielder, and Dyson led that group with seven Outs Above Average last season, according to Statcast™. Maybin was at plus-2 two while Jay was minus-3.
Dyson, 33, has stolen at least 25 bases in each of the past six seasons and would be a big boost to a Giants club that ranked 20th in the Majors with 76 steals last year. Jay has 51 steals in eight Major League seasons, but his .738 career on-base-plus-slugging percentage bests Dyson's .677 total.
Maybin owns a career .693 OPS and stole 33 bases during his time split between the Astros and Angels last season.
Brewers remain interested in Arrieta, Moustakas
The Brewers "continue to be in" on free-agent right-hander Jake Arrieta and third baseman Mike Moustakas, according to Jim Bowden of SiriusXM.
The Brewers have been known to be seeking starting pitching in free agency, and Arrieta would certainly be a boost to Milwaukee's rotation, especially with Jimmy Nelson's 2018 status unclear. Nelson, who underwent surgery on his right shoulder in September, went 12-6 with a team-best 3.49 ERA and 199 strikeouts in 175 1/3 innings last season.
It was reported earlier in January that the Cubs and Cardinals were the two clubs most interested in Arrieta's services, but the Brewers' desire to sign the 2015 National League Cy Young Award winner could create a potential bidding war between the NL Central rivals.
Arrieta, 31, went 64-29 with a 2.67 ERA in 119 starts for the Cubs over the past four seasons.
According to Bowden, the Brewers' interest in Moustakas comes with the idea that the club "could trade Travis Shaw" to the Yankees, Braves or Mets.
Milwaukee does not necessarily have a need at third base with the incumbent Shaw being younger and cheaper than Moustakas. The 27-year-old Shaw, under team control through 2022, also excelled for the Brewers last season, batting .273/.349/.513 with 31 home runs and 101 RBIs in 144 games.
