MLB trade rumors: One player each team should target

Miami Marlins: Tyler O’Neill

The Marlins have few trade chips that are not locked into long-term contracts. There’s an outside chance owner Jeffrey Loria decides it’s not working out with Giancarlo Stanton, Marcell Ozuna, and Christian Yelich and decides to make all three available for trade, but that type of move should be done in the offseason with more time to develop a concrete plan. Miami does have a mid-range trade chip to move in starting pitcher Dan Straily.

Straily was the fourth-place finisher in the 2013 AL Rookie of the Year vote when he went 10-8 with a 3.96 ERA for Oakland. Ineffectiveness would threaten to derail his career, and Straily was traded three times before resurfacing with the Reds in 2016. Over the last two seasons, the right-hander has a solid ERA and record even if the advanced metrics do not back it up.

In the pecking order of the pitching market at the deadline, Straily does have value, but he will be part of the second-tier of starting pitchers who could be dealt. He makes sense for the Seattle Mariners, a team with a pressing need for depth in the rotation but not much to offer in terms of prospects.

Tyler O’Neill is Seattle’s second-best prospect, but is not necessarily a guarantee at the MLB level. He has great raw power, but a long swing and pull-happy approach that can be easily exploited by the best pitchers. The 22-year-old has struggled at Triple-A this year. O’Neill has plus-power, but does not necessarily fit with the speed-defense-contact vision of Seattle GM Jerry Dipoto.
