The Mariners entered Saturday 73-68 and stood second in the AL West, 3.5 games behind the Astros for the top spot. They held the final wild card spot in the American League playoff picture, half a game ahead of Texas to remain in the playoff field. On Friday night, Seattle finished with six hits as Leo Rivas (RBI) and Jorge Polanco (run) each had two. Logan Gilbert threw six innings, allowing one run on five hits with one walk and seven strikeouts, but didn’t factor in the decision. Gabe Speier (2-3) took the loss in relief as he allowed three runs on four hits with no walks or strikeouts without retiring a hitter.
Luis Castillo gets the call for the Mariners on getaway day as he logs his 29th start of the season in this one. He is 8-8 with a 3.94 ERA, a 1.294 WHIP, 44 walks and 138 strikeouts over 155.1 innings of work this year. Castillo took the loss in his last start, which came against the Rays on the road Monday.

Atlanta Looking to Secure Series Win
Atlanta won their second straight as they prevailed in the opening game of this set Friday night at home.

Spencer Strider is on the mound for the Braves as he makes his 20th start of the season in this contest. He is 5-12 with a 4.97 ERA, a 1.391 WHIP, 41 walks and 106 strikeouts over 101.1 innings of work on the year.

Moneyline Pick for Mariners vs. Braves
- Mariners (4 units)
While Atlanta took the opening game of the set Friday night and the Mariners are reeling, it’s tough to see the Braves maintaining that momentum. Strider has sputtered all season long and is 0-4 with a 9.13 ERA while allowing eight homers over 23.2 innings of work in that span. Seattle has struggled, but they are trying to fight to maintain a wild-card spot with their lead down to a tenuous half-game. Castillo has struggled in his last few turns and we’ve discussed the road splits of Seattle’s staff this season. However, with no room for error and the struggles Strider has had this season, gives the Mariners the edge.
Over/Under Pick for Mariners vs. Braves
- Over (4 units)
Seattle has seen the over go 76-59-6 in their first 141 games of the year entering Saturday night. The Mariners are 13th in the majors with 4.53 runs per game, a number that climbs to 4.79 runs per game on the road. They have an average total of 9.01 runs per game and that number rockets to 9.80 runs per game as the visiting team. Atlanta entered Saturday night having gone under the total in 68 of their 141 games, with 10 pushes, on the season. The Braves are 15th in the majors with 4.41 runs per game, a number that slides to 4.36 runs per game at home. Atlanta has an average total of 8.91 runs per game and that number drops slightly to 8.84 runs per game at home this season. With both pitchers sputtering at the moment, take the over in this contest.
