15 Kyle Seager 3B

Seager isn't in Friday's starting nine against the Rangers, Greg Johns of MLB.com reports.

With the Mariners out of postseason contention, Seager will get the day off. Kris Negron draws the start at the hot corner and is slated to bat ninth.

Seager entered an extra-innings win over the Athletics on Tuesday as a pinch hitter and laced a game-tying RBI single in his one at-bat.

It was a night of pinch-hit success for the Mariners as a whole, with Seager making a key contribution by singling on a 2-1 pitch with two outs in the ninth to bring home Ben Gamel with the tying run. The veteran third baseman has had a disappointing season in terms of his slash line (.221/.273/.401), but he's shown some signs of life recently by reaching safely in 12 of his last 14 games.

Seager is not in the lineup Tuesday against the A's.

Seager will head to the bench as manager Scott Servais stacks right-handed hitters against southpaw Brett Anderson. In his place, Kris Negron will start at the hot corner and hit sixth.

Seager went 2-for-4 with a home run and two RBI in Wednesday's 9-0 rout of the Astros.

After his first-inning single brought home Robinson Cano, Seager's solo shot in the sixth gave him 22 homers and 76 RBI on the year. The veteran third baseman came into the contest with a career-low .248 BABIP and .220 batting average, but his power numbers remain as steady as ever -- Seager's hit between 20 and 30 home runs, and collected between 69 and 99 RBI, in every season since 2012.

Seager went 2-for-4 with a walk and a run in a win over the Astros on Monday.

Seager is in the midst of one of his more consistent offensive stretches of the season, as he's now hit safely in seven consecutive games. The third baseman has four extra-base hits (three doubles, one home run) during that span and has boosted his September average to .250, an unspectacular number that nevertheless represents a significant improvement over the .183 figure he generated in August.
