The Mariners opened this four-game series with a dominant 6-0 win Thursday night behind six scoreless innings from George Kirby and home runs from Cal Raleigh and rookie Cole Young. 

Texas remains one game behind the Mariners’ second-place standing in the division after suffering its third consecutive loss and falling to an abysmal 22-33 on the road. 

Friday’s rematch features right-hander Logan Gilbert (3-4, 3.36 ERA), who owns a sparkling 1.94 ERA at home this season, against Jack Leiter (7-6, 4.09 ERA), whose underlying numbers suggest his recent run of solid starts may not be sustainable.

Here’s how I’m breaking this one down.

Rangers vs. Mariners Prop Bet

• Julio Rodriguez Home Run (+450 at FanDuel)

I supported J-Rod to go long in my Daily Dingers column Friday because he has just crushed the Rangers this season, batting .359 with a home run, four RBIs, and eight runs in nine games. He’s been even more dominant against Leiter, going 6-for-11 with two homers in their matchups. Since the All-Star break, J-Rod has launched five home runs in 14 games and ranks in the 95th percentile in swing speed, making him one of the hottest hitters in baseball. At +450, his home run odds reflect both recent form and a favorable matchup.

Rangers vs. Mariners Prediction and Pick

The public is loving Seattle moneyline, but I have no interest in the expense. This team has covered the run line in six straight home matchups following a win against the Rangers. The Mariners are 8-2 in their last 10 head-to-head meetings and have outscored the Rangers 19-4 in their last four games at T-Mobile Park. Gilbert has been especially sharp at home, with a WHIP of 0.90 and an opponent batting average under .200 over his last five starts in Seattle. Then there’s Leiter who sports serious reverse splits, giving up a .361 OBP to right-handed hitters — a major red flag against a Seattle lineup that includes Eugenio Suarez, who owns a 151 wRC+ vs righties this year. Add in Texas’ bullpen struggles over the last month (4.20 xFIP) and a Rangers lineup hitting just .232 on the season, and Seattle’s path to another multi-run win becomes clear. 

Pick: Mariners -1.5 (+114 at FanDuel)
