The 2015 MLB season has hit the month of June, which means summer is finally here and before you know it, so will the MLB trade deadline. The deadline to move players via trade hits on July 31st, so we can probably expect to see a lot of chatter involving some big names heat up starting this month.

We’ve already heard a few whispers involving stars like Cole Hamels and Troy Tulowitzki, while Josh Hamilton already got dealt back to the Texas Rangers. More big moves are coming and it’s time to filter through some of the top MLB trade rumors we’ll want to be monitoring:

Johnny Cueto

Let’s be clear. Cueto isn’t officially on the market, but his agent does seem to think that’s not out of the question. Players set to hit free agency in any sport become expendable, because their current team is then in danger of getting either nothing or minimal compensation (draft picks or money) for losing them. The Reds are in an interesting position, as they’re just 22-27 through the first 49 games but still arguably have enough talent to turn things around. The closer we get to that not happening, though, the closer Cueto gets to hitting the trading block.

With just two months to go before the MLB trade deadline hits, we might start to see the Johnny Cueto trade rumors heat up. An obvious trading partner could be the L.A. Dodgers, who could use one last ace to push them over the top. They already boast two of the game’s top pitchers, but with Cueto as their third or possibly even second best ace, they’d suddenly look unbeatable on paper. Considering their pitching has floundered a bit in post-season play, this just might be a move they deem necessary to ensuring they can take the next step in a deep playoff run.

There is also a good chance someone else steps in and tries to land Cueto to help them turn their season around and then possibly try to lock him up, long-term. One team that matches that profile is the Boston Red Sox, who aren’t so far out of contention to swing a wild move, but badly need pitching help as they stand. Cueto isn’t a lock to be shipped, but his name is just now being tossed around and we might hear a lot more about him in the near future.

Troy Tulowitzki

The star shortstop has had his hand in trade rumors all season, as it’s been made clear that he wants to win and he probably won’t be doing that anytime soon with the Colorado Rockies. Tulowitzki is easily one of the top shortstops in the game and if he doesn’t want to waste his best years with a losing squad, he doesn’t have to. Numerous teams would love to pay a fair price to get his hitting and defense, not to mention his power. The big questions, of course, are is he really trying to get out of town, and if so, where could he be headed?

Tulowitzki already took some step backs from full blown trade demands, so it’s unclear if he’s actually willing to try to force his way out of Colorado. By all accounts, it sounds more like he’s disappointed that the Rockies can’t win, rather than upset with his position. Still, the situation could lead to the 30-year old shortstop playing elsewhere as soon as this year.

Cole Hamels

The Phillies have been terrible for a while now and they seem to be hitting rock bottom in 2015. They still have a top shelf pitcher in Hamels, though, and now could be a good time to ship him off for some assets. Hamels has no issues with departing, as he’d rather spend his days with a true contender than waiting and hoping the Phillies make the right moves to turn things around. That makes Hamels one of the top players on the move, as he could slide right in and round out any pitching rotation. He has somehow had a pretty good season with arguably the worst team in baseball, so it’s definitely worth wondering just how good he’d look with a winning ball club. The big question, then, is who would make a deal for Hamels? Contending teams like the Kansas City Royals and Houston Astros could take notice, while the Boston Red Sox and Texas Rangers also could be potential trade partners.

Ben Zobrist

It’s been made known that the Chicago Cubs have eyes for Ben Zobrist, who would provide great experience and versatility both as a hitter and defender. Zobrist’s current deal is up after this season, so the struggling Athletics are sure to be open to moving him so they don’t lose him for nothing. The Cubs are a surprise team that has playoffs on the mind now, and netting such a solid player for the rest of the year could help solidify their standing.

Yasiel Puig

Puig is probably the most interesting name in MLB trade rumors, because he’s a terrific talent and the Dodgers haven’t specifically said anything about wanting to trade him. The problem is, a hamstring issue robbed him of the past month and made it quite clear that the Dodgers have loads of serviceable talent behind him. Translation? As good as Puig obviously is, he could be expendable if the right deal can be made. That could very well be a deal that involves the aforementioned Johnny Cueto, someone like Mets pitcher Noah Syndergaard or any numbers of top flight pitchers (especially ones with expiring deals). It’s an odd deal considering Puig can be so deadly offensively and is under team control for years to come, but it’s a move that could make a lot of sense if the Dodgers can vastly improve their pitching rotation.

None of these players are locks to be moved, but they’re atop the MLB trade rumors and could be playing somewhere else before the deadline hits. Think someone else deserves to make the list? Let us hear it in the comments below!
