MLB notebook: Back injury ends Marte's season

[September 21, 2019]  Arizona Diamondbacks All-Star outfielder/infielder Ketel Marte has a stress reaction in his lower back and will miss the remainder of the season, general manager Mike Hazen told reporters on Friday.

According to the Arizona Republic, Marte will not need surgery and is expected to be ready for spring training with an offseason of rest and rehab. The team's official Twitter feed retweeted a report from MLB.com confirming the news.

The injury brings to an end an MVP-caliber season for a player who has been the main driving force behind a team still competing for a playoff spot. The Diamondbacks entered Friday five games behind Milwaukee for the second National League wild-card slot.

Martel, 25, ends his season with a .329 average, 32 home runs, 97 runs and 92 RBIs in 144 games.

"This is something that, baseball aside, this is a bigger issue, obviously," Yankees manager Aaron Boone said to reporters.

--Hall of Fame manager Tony La Russa reportedly has agreed to remain with the Boston Red Sox organization as an adviser despite the recent firing of Dave Dombrowski as president of baseball operations.

La Russa, who won three Word Series as manager of the Oakland Athletics (one) and St. Louis Cardinals (two), was a special assistant to Dombrowski, who was fired Sept. 8.
