Cincinnati Reds Send Down Veteran Arm, Promote Familiar Face

In this story:
The Cincinnati Reds are optioning Sam Moll and promoting Reiver Sanmartin, according to Charlie Goldsmith.
The Reds needed a fresh arm in the bullpen with Nick Lodolo scratched from his start on Tuesday against the Blue Jays.
Sanmartin has not pitched in the big leagues since undergoing Tommy John surgery in 2023. In 2022, he had an ERA of 6.32 in 45 games for the Reds.
The 29-year-old has had a nice season with Triple-A Louisville, pitching to a 2.79 ERA in 41 games out of the bullpen.
Sam Moll has struggled to find his form this season. The left-hander has a 6.38 ERA in 23 games with the Reds this season. After coming over to the Reds at the trade deadline in 2023, Moll had been one of Cincinnati's most valuable arms out of the bullpen over the last two seasons. After starting out the season injured, he just hasn't been able to regain that form this season.

Reiver Sanmartin is getting called up. Sam Moll optioned.
