Reiver Sanmartin

The San Francisco Giants claimed left-hander Reiver Sanmartin off waivers from the Cincinnati Reds on Thursday. The move provides a fresh start for Sanmartin, who had spent the last six seasons as part of the Reds organization. He appeared in one big-league game during the 2025 campaign.

Sanmartin, who turns 30 in April, spent most of last season at Triple-A Louisville, where he tallied a 2.67 ERA and a 1.24 WHIP. He also posted a 55:18 K:BB ratio across 67.1 innings at the Triple-A level.

The Cincinnati Reds optioned Reiver Sanmartin to Triple-A Louisville on Wednesday.

As expected, Sanmartin pitched in Wednesday's game after Nick Lodolo was scratched due to illness. He allowed one unearned run on two hits over 1.2 innings. In a corresponding move, the Reds recalled Lyon Richardson from Triple-A to add a fresh arm to the bullpen.

The Cincinnati Reds selected Reiver Sanmartin's contract from Triple-A Louisville on Tuesday.

Fantasy Impact

With Nick Lodolo (illness) scratched from Tuesday's start against the Toronto Blue Jays, the Cincinnati Reds have called up Sanmartin. In what is expected to be a bullpen game, Sanmartin could be used in a multi-inning role. This season in Triple-A, he has posted a 2.79 ERA and 1.24 WHIP across 58 innings.

The Reds re-signed Reiver Sanmartin to a minor league deal.

Fantasy Impact

Sanmartin will continue to add relief depth in the Reds organization.

Reiver Sanmartin was optioned to Triple-A after his start on Sunday against the Rockies, during which he allowed six runs on six hits and two walks in 2/3 of an inning.

Fantasy Impact

The Reds needed to trim their roster to 26, and Sanmartin's 13.78 ERA and 2.27 WHIP made the choice to option him pretty easy. He does have a 4.76 xFIP, suggesting that perhaps he hasn't been quite as bad as his numbers suggest, but there's absolutely no reason to hold him now in any format.
