2023 Fantasy Outlook
Sanmartin was utterly dreadful in four starts for the Reds last season. He put up a 19.85 ERA and 3.09 WHIP in those outings, with batters hitting .456 with a 1.294 OPS against the left-hander. Sanmartin was much better in relief, though, with a 2.96 ERA over 41 appearances while limiting them to a .694 OPS. The southpaw's drastic platoon splits (.717 OPS versus left-handed batters, .933 OPS against right-handers) also point to the bullpen being his long-term home. Sanmartin currently projects as the lone lefty in manager David Bell's relief corps, so he could find himself in high-leverage spots when the situation calls for it. Read Past Outlooks

Called up from Triple-A
The Reds recalled Sanmartin from Triple-A Louisville on Monday, Charlie Goldsmith of The Cincinnati Enquirer reports.
ANALYSIS
Sanmartin broke camp in the major-league rotation but was optioned within a month after struggling to an awful 13.78 ERA across five appearances. His 7.36 ERA in 18.1 innings as a swingman for Louisville hardly inspires confidence, though he recently righted the ship, giving up three earned runs while striking out 15 over 10.1 innings in his four most recent appearances.

2022 Fantasy Outlook
Sanmartin is still a bit of an unknown in many circles, but he had a 3.94 ERA, 54.0 GB% and 19.2 K-BB% in 82.1 innings at Triple-A and then finished his season with two strong starts in the majors. Of course, it helped that both of those starts came against the Pirates. The 25-year-old lefty only averaged 89.5 mph on his fourseam fastball, but it had serious horizontal break and was very tough to pick up from a three-quarters lefty slot. His slider and changeup are strong secondary offerings, so it's a starter's repertoire. Given the lack of velocity, we recommend treading cautiously, as deception artists often have a short shelf life in the majors. However, Sanmartin has a decent chance of opening the year with a spot in the Reds' starting rotation, and he has a good recent statistical track record.
