that Don Mattingly is expected to return next year as manager of the Miami Marlins http://www.diamondbacksfanproshop.com/authentic-zack-greinke-jersey , providing some dugout continuity for a last-place team in transition.Mattingly has one season to go on a four-year contract he signed when he joined the Marlins for the 2016 season.“Is he going to be back in 2019?” Jeter said. “He’s under contract. Yeah.”The Marlins will finish last in the NL East in Jeter’s first year as CEO. They began their final home series of the season Thursday with a record of 59-92, giving Mattingly a three-year record of 215-259 (.454).Mattingly has said he likes the challenge of developing the Marlins’ many young players. He also has embraced Jeter’s approach to rebuilding a franchise that hasn’t had a winning season since 2009, the longest streak in the majors, and hasn’t been to the playoffs since 2003.“The one thing you can count on with Derek is that what he says, he’s going to do,” Mattingly said. “He talked about building the minor league system Shelby Miller Jersey , building this thing the right way. I don’t think there’s one thing he talked about publicly that he hasn’t backed up with his actions. You trust what he says and what he’s going to do.”This year’s poor record was expected after the Marlins traded half their starting lineup for prospects last offseason to reduce payroll and fortify a weak farm system.Even so, losing has been tough for Jeter, who played for a perennial contender when he was shortstop for the New York Yankees.“That’s the ultimate judge for a team — wins and losses,” Jeter said. “But this is a transitional year for us to learn as much as we possible could about this organization.”The Marlins will finish last in the majors in attendance, and last in the NL for the 13th time in 14 years. Their crowds have averaged fewer than 10,000 Chris Owings Jersey , the worst figure in the majors since the Montreal Expos’ final season in 2004.“That’s something we need to improve,” Jeter said. “Where we’re starting from, the only way we can go is up.” The biggest rivalry in baseball will continue at Fenway Park on Thursday when the American League East-leading Boston Red Sox (75-34) host the New York Yankees (68-38) in a near pick'em divisional matchup at the sportsbooks.Both teams are coming off losses heading into this key four-game series, with six more meetings set to take place over the last two weeks of the regular season.MLB betting line: The Red Sox opened as -130 favorites (wager $130 to win $100); the total is at 10 runs, according to sportsbooks monitored by OddsShark.

The Yankees should also have an advantage in this series-opening pitching matchup with veteran southpaw CC Sabathia (6-4, 3.53 ERA) on the mound.The Yankees have won four of the previous five times the 38-year-old has toed the rubber, with him allowing two runs or less three times during that stretch. Rich Schultz/Associated PressSabathia has also notched a victory against Boston once already this year Curt Schilling Jersey , allowing one run and six hits in seven innings of an 8-1 win at home on June 29. Why the Red Sox can pay on the MLB linesThe Red Sox have been MLB's best team for a while now, and they have had some success versus Sabathia this season as well. In his first start against the veteran on May 10, they had four runs and nine hits off him in four innings en route to a 5-4 victory.Converted reliever Brian Johnson (1-3, 3.45 ERA) will get the call here with Chris Sale on the disabled list, and he has pitched well lately despite not having anything to show for it. In his last two starts, Johnson has not allowed an earned run in 10.2 innings http://www.diamondbacksfanproshop.com/authentic-zack-greinke-jersey , with the Red Sox getting outscored 7-1 in a pair of losses. More run support would help him.Smart betting pickBoston leads New York by 5.5 games in the race for the AL East title and owns MLB's best home record, too, at 38-15. The Red Sox have less favorable pitching matchups the rest of the series, so look for them to earn a win right away and relieve some pressure.MLB betting trendsNew York is 2-4 in its last six games on the road.Boston is 4-1 in its last five games.Boston is 14-3 in its last 17 games at home.All MLB odds and betting trends according to Bleacher Report's official odds partner, OddsShark.
