Julio Rodriguez broke his left pinkie in Game 3 of the ALDS against the Houston Astros, according to Seattle Mariners lead executive Jerry Dipoto.

An exit exam this week revealed the injury to the 21-year-old, but he's not expected to need surgery.

Rodriguez got hurt sliding headfirst into second base on a double in the eighth inning of what became an 18-inning marathon the Mariners lost 1-0.

The rookie also dealt with back and wrist injuries during the season, with the lower back strain popping up late in the season and costing him time when the Mariners were pushing for a postseason spot.

"He just needs to have some downtime, get his body feeling good again," Scott Servais said. "He went through a lot. He's never played this much baseball, certainly at this level, the intensity and the emotional toll that it takes on you when you go through a season like that."
