Rangers - D-
Additions - Carson Coleman, Kirby Yates, Tyler Mahle, Diego Castillo
Subtractions - Jordan Montgomery, Mitch Garver, Chris Stratton, Travis Jankowski, Austin Hedges, Aroldis Chapman, Jake Ordorizzi, Brad Miller, Robbie Grossman, Martin Perez, Will Smith, Ian Kennedy, Brett Martin, Matt Bush
The defending World Series champions were expected to retain a lot of the group that propelled them to their championship. They still could, but they are also expected to work under a tighter budget. The Mariners took Mitch Garver from them, they are likely to be priced out of the Jordan Montgomery services and have lost a couple of decent bullpen options, for a bullpen that was already pretty weak.
They did add Tyler Mahle, a high-upside starting pitcher, but he is expected to miss the first part of the year. Kirby Yates is a solid bullpen addition, again, for a bullpen that was pretty bad. They also lost Martin Perez, a solid back of the rotation arm that would've been valuable for a team dealing with a lot of injuries.
The Rangers have arguably had the worst offseason of the three teams expected to contend for the division title. With the loss of Garver, Montgomery, Chapman, Perez, paired with the news that Max Scherzer will be out until midseason due to a herniated disk, the Rangers could look like a very different team. They still have the firepower with Seger, Semien, Garcia and Lowe, but this offseason hasn't been kind to the Rangers.
