The Seattle Mariners' season may be over, but one of the benefits of not playing in the World Series is that it allows you a get a head start in planning for next year.
The Mariners potentially improved their team for 2023 by claiming a veteran pitcher off waivers from the Kansas City Royals.
Seattle added some pitching depth by acquiring Luke Weaver from Kansas City. Weaver has had an up-and-down career since debuting in 2016, going 24-36 with a 4.79 ERA and a 1.40 WHIP over 450 2/3 innings with the Royals, St. Louis Cardinals and Arizona Diamondbacks.
Primarily a starting pitcher before last year, Weaver was used mostly as a reliever in 2022. The new role didn't help his performance, however, as he posted the second-worst ERA (6.56) and highest WHIP (1.82) of his career.
The Mariners are hoping the 29-year-old righty can bounce back in 2023, as he did show some encouraging signs in his performance last season. Weaver had 38 strikeouts in 35 2/3 innings and allowed only one home run while producing the best FIP (2.69) of his career.
Whether he returns to the rotation or remains in the bullpen, Weaver will try to help an ascendant Seattle team return to the playoffs after getting swept in the ALDS by the Houston Astros.
