Seattle Mariners Promote Several Interesting Pitching Prospects

The 24-year-old Raeth has posted a 2.45 ERA with 45 strikeouts in 40.1 innings pitched across 32 appearances this season.

The 22-year old Costa Lemos had a 3.68 ERA with 59 strikeouts in 51.1 innings pitched across 26 outings.

The 25-year-old Schapira has a 2.18 ERA and has fanned 22 batters in 20.2 innings across 17 appearances.

Romero, 21-years-old, has a 3.79 ERA and has struck out 46 batters in 54.2 innings across 13 outings (nine starts).

Diaz, who's also 21-years-old, has posted a 7.96 ERA with 36 strikeouts in 31.2 innings across 23 outings.

Seattle has one of the best farm systems in the league according to several publications. MLB Pipeline has eight Mariners prospects ranked in the top 100 and Baseball America also ranks eight prospects in its own respective top 100.

Seattle also has depth in its farm system beyond its top 100 prospects. Players not in the top 100 like Ben Williamson, Rhylan Thomas and Logan Evans have all received playing time with the team this season and weren't in the top 100 going into the season, and there's a chance that these crop of pitchers make an impact on the major league club in the future.
