Ryan Zimmerman (hamstring) went 1-for-7 as the DH on Thursday in a simulated game at the Nationals' spring training complex in Viera, Florida.
Zimmerman is slated to play seven innings in left field Friday before being reevaluated. The Nationals are hoping to have him back for the final few days of the regular season to get him ready for the playoffs.
Adam LaRoche is resting his back Thursday.
Most of the Nationals' regulars are back in the lineup Thursday after resting on Wednesday, but LaRoche needs another day. He's expected to return Friday.
Arismendy Alcantara (wrist) is out of the Cubs' lineup again Thursday.
Alcantara suffered a right wrist sprain when he slammed into the outfield wall on Monday and will miss his third straight game Thursday, but he plans to hit in the cage and take batting practice. If all goes well, he could play Friday.
Mike Trout is not in Thursday's lineup against the Mariners.
Not surprisingly, the Angels' regulars are sitting after the team wrapped up the AL West on Wednesday night. Here's the lineup King Felix will face: Tony Campana CF, Gordon Beckham SS, Brennan Boesch RF, C.J. Cron DH, Efren Navarro 1B, Grant Green 2B, Hank Conger C, Luis Jimenez 3B, Shawn O'Malley LF.
Nolan Arenado (pneumonia) could miss the rest of the season.
Arenado came out of Sunday's game with a chest contusion and an MRI on Monday revealed signs of pneumonia. He's doing better, but there just might not be enough time for him to make it back at this point.
