Casey Lawrence Fantasy Stats

Seattle Mariners right-hander Casey Legumina will serve as the opener on Tuesday against the hosting Chicago White Sox, according to Seattle Sports' Shannon Drayer. Right-hander Casey Lawrence is on the taxi squad and is expected to be added to the active roster as the bulk reliever for Tuesday's contest. Legumina has been a key reliever for the first-place Mariners this year with a 3-1 record, 1.84 ERA, 1.09 WHIP and 14:8 K:BB in 14 2/3 innings out of the bullpen. This will be the 27-year-old's first actual "start" in the big leagues, but he won't be a recommended DFS streamer, as he'll likely only go an inning or two before handing the ball to Lawrence. The 37-year-old Lawrence should also be avoided for fantasy purposes, even against the struggling White Sox. He's allowed 14 runs (seven earned) while walking one and striking out five in 12 2/3 relief innings for Seattle and Toronto in 2025.

The Seattle Mariners have signed pitchers Sean Poppen and Casey Lawrence to minor-league deals while both players have received an invitation to big-league spring training. Poppen, 29, didn't appear in the big leagues in the 2023 season but rather scuffled to a 6.33 ERA across 47 outings at Triple-A El Paso within the Padres organization. He owns a career 5.08 ERA across 63 MLB appearances between the Twins, Pirates, Rays, and D-backs. Lawrence, 36, appeared in 15 games for the Cardinals last season but scuffled to a 6.59 ERA across 27 1/3 innings of work. He also tossed a 4.76 ERA across 104 innings at the Triple-A level between the Cardinals and Blue Jays organizations. Lawrence owns a career 6.75 ERA across 59 MLB appearances between the Blue Jays, Mariners, and Cardinals.

Seattle Mariners first baseman Dan Vogelbach will make the Opening Day roster. Vogelbach's inclusion makes sense after Mike Ford was returned to the Yankees, but confirmation is always nice. It is difficult to trust Vogelbach (and he will be platooning with Ryon Healy), but he is certainly worth monitoring going forward.
