27-Year-Old Second Baseman2B
Seattle Mariners
2025 Fantasy Outlook
Rivas spent the season shuttling between the Mariners and Triple-A Tacoma. His game is getting on base and running, fueled by an extreme patient approach. He got on base at a 41 percent clip with Rainers, helping him swipe 24 bags in 30 tries. He was 3-for-3 with the big club, albeit with a .333 OBP in 86 plate appearances. Rivas can play second base, shortstop and third base. The Seattle starters in front of him all have injury or performance concerns, yielding a pathway to playing time. Rivas is only an option in AL-only, but he can be a source of end-game speed. Read Past Outlooks

Filling bench role with Moore back
2BSeattle Mariners
May 7, 2025
Rivas is out of the lineup for Wednesday's game against the Athletics.
ANALYSIS
The 27-year-old had started at second base six times over a seven-game stretch from April 27 through Monday, but his time as a regular in the Seattle lineup appears to be over after Dylan Moore (hip) returned from the injured list Tuesday. Rivas will hit the bench for the second straight day while Moore picks up the start at the keystone.

Latest Fantasy Rumors
Up on taxi squad
2BSeattle Mariners
April 25, 2024
Rivas has joined the Mariners as a member of the taxi squad Thursday while J.P. Crawford deals with an oblique injury, per Shannon Drayer of Seattle Sports 710 AM.
ANALYSIS
Crawford is sitting out Thursday for the second straight game, but it remains to be seen if he'll require a stint on the injured list. Rivas joined the Mariners as a non-roster invitee in January and has enjoyed a strong start at Triple-A Tacoma with an .884 OPS and five steals in 18 games. The 26-year-old is unlikely to have a regular role if added to the active roster, with Dylan Moore likely to take over at shortstop for Seattle.
