SAN DIEGO >> On the same day they acquired veteran leadoff hitter Jimmy Rollins, the Dodgers dealt their leadoff hitter in 2014, Dee Gordon, to the Miami Marlins.According to multiple reports Wednesday, Gordon and pitcher Dan Haren were going from the Dodgers to the Miami Marlins for four players: left-handed pitcher Andrew Heaney, utility player Austin Barnes, right-handed pitcher Chris Hatcher and utility player Enrique Hernandez.The trade, like the Rollins trade, has not been formally announced by either team. There is good reason to believe that a third or fourth team could become involved in one or both trades, which general manager Farhan Zaidi hinted in his media briefing Tuesday.Zaidi also said Tuesday that Gordon “is our second baseman” and the Dodgers were not offering him in trades. Newsroom GuidelinesNews TipsContact UsReport an Error That must have changed at some point overnight. Heaney was reportedly coveted by multiple teams. The 23-year-old was the ninth overall pick in the 2012 draft. He pitched in Double-A, Triple-A and eventually reached the majors this past season, throwing 29 1/3 innings and allowing 19 runs for the Marlins.Hatcher, 29, made 52 appearances out of the Miami bullpen and posted a 3.38 ERA with 60 strikeouts in 56 innings.Hernandez, 22, played six positions in his rookie year, and was part of a five-player trade between the Astros and Marlins in July. He posted a combined .248/.321/.421 slash line.Barnes, 24, is a native of Riverside who has played four minor-league seasons in the Marlins’ organization. Last year at Double-A he slashed .296/.406/.507.All four players are under team control for 2014, an attractive option for a Dodgers club looking to create a more flexible roster. Since the Dodgers’ 40-man roster was full when the day began, they would certainly not be able to take on five players while trading only two. At least one further move is necessary to complete the picture. What will the roster look like once it’s complete?“I don’t think any of us know what it’s going to look like,” Dodgers manager Don Mattingly said on a conference call Wednesday afternoon. “I think there’s a lot going on right now.”Dodgers executives cancelled their daily media briefing Wednesday evening as details of the trades leaked.If true, the trade with the Marlins leaves the Dodgers’ roster without a clear-cut second baseman and only three pitchers who started more than two games for them last season.Gordon, 26, led the National League in stolen bases with 64. He was eligible for arbitration and was tendered a contract by the Dodgers for 2015 but had not signed.Gordon made his first All-Star team in July with a strong first half, but a second-half slump left him with a .326 on-base percentage for the season, well below the norm for an All-Star caliber leadoff hitter.“Part of his struggles is just part of being a young player,” Mattingly said. “They’re going to grow and go through stretches where they get tired. It’s cat and mouse, back and forth. You have success, (opposing pitchers) start chasing him in a different way. … He has to make the adjustments back. That’s what was part of his second half last year.”Coincidentally, Gordon made two community appearances in a Dodgers uniform on Wednesday in Los Angeles.Haren, 34, rejoined the Dodgers by exercising a $10 million player option in his contract for 2015. He went 13-11 with a 4.02 ERA in 2014.“I thought he saved us the way he pitched early,” Mattingly said of Haren. “He had a bunch of wins early in the season. I think he hit an extended four or five-game stretch that he struggled, got off track a bit mechaniccaly. But you still were comfortable with Danny because you know he’s not going to panic, not going to worry. I loved what he brought to this club, his makeup. I thought he had a tremendous year last year.”The two trades would allow the Dodgers to save more than $12 million in salary according to some reports, but those do not take into account which players the Dodgers would send to Philadelphia to complete the Rollins trade.McCarthy close to signingThe Dodgers and free agent right-hander Brandon McCarthy have agreed to terms on a four-year contract, according to multiple reports Wednesday.The 31-year-old is 52-65 in nine major-league seasons with the White Sox, Rangers, A’s, Diamondbacks, and Yankees.
