James Jones has been the Mariners’ starting center fielder since making his MLB debut in mid-April, logging more than 300 plate appearances, but now the 25-year-old is headed back to Triple-A following yesterday’s trade for Tigers center fielder Austin Jackson.
Jones got off to a good start in Seattle, but has hit just .258 with zero homers and a .600 OPS in 79 games overall, including an ugly 64/12 K/BB ratio. He has great speed, swiping 20 bases while being caught just once, but based on his early MLB production and track record in the minors it’s not clear if Jones will hit enough to be a quality regular.
With just over a week left in the regular season, the Diamondbacks have elected to shut down infielder/outfielder Ketel Marte. Marte has been dealing with some lower back inflammation and stiffness over the last few days; on Friday, the team revealed that he was diagnosed with a stress reaction as well.
It doesn’t look as though the injury will compromise Marte’s 2020 campaign, but as Craig noted on Wednesday, his absence will likely have some effect on his NL MVP candidacy. The 25-year-old will wrap his first All-Star season with a .329/.389/.592 batting line, 32 home runs, a .981 OPS, and a staggering, career-best 7.1 fWAR through 628 plate appearances.
Marte told reporters Thursday that the back pain had been an issue “for the past two months,” though he didn’t comment on the severity of the injury. Despite his ability to play through the pain since July, the issue has clearly escalated in the last week or so. Although the loss of their most valuable contributor may have a negative impact on the D-backs’ chances of competing in the postseason, it’s undeniably a wise move to let Marte recuperate rather than pushing him to play for another week and running the risk of further injury.
Entering Friday’s series against the Padres — their last road series of the regular season — Arizona still has a sizable gap to close in order to earn one of two NL wild card spots. They’re five games out of postseason contention, with the Nationals, Brewers, Cubs, Mets, and Phillies ahead of them.
