With MLB odds showing real value on this game, I’m banking on elite pitching to dominate Friday’s matchup. Gavin Williams and Luis Castillo have both been sharp lately — Williams owns a 2.13 ERA this month while Castillo posted six shutout innings in his last home start. Neither lineup is red-hot, and both strike out at a high clip. The MLB same game parlay odds for a total prop combo should offer solid value.
Top 4 Guardians vs Mariners Parlay Picks
1. Total Pick: Under 7 Runs (Ev)
Both starters have held opponents in check: Williams has allowed just six hits in 12.2 June innings, while Castillo’s only bad outing this month came via three solo homers. Cleveland is hitting just 229 on the road. Seattle isn’t much better at home, hitting .217 with a .662 OPS. This has all the makings of a 3-2, low-scoring grinder.

2. Pitcher Prop: Gavin Williams Over 5.5 Strikeouts (-141)
Seattle hitters are striking out more than 600 times already this season, and Williams has double-digit K upside. He’s racked up 11 strikeouts over two June starts and had 6+ Ks in three of his last five outings. He also dominated lineups like Philly, Milwaukee, and LAA — all more dangerous than Seattle’s current order. This is one of my favorite MLB player props on the board.
3. Player Prop: Cal Raleigh to Hit a Home Run (+300)
The Mariners haven’t done much offensively lately, but Raleigh’s been the exception. He leads the team with 26 bombs and a .629 SLG — and he’s hit 7 homers over his last 11 games. Williams can give up the occasional long ball (9 HR allowed), and Raleigh feasts on righties. If anyone gets to the Guardians’ starter, it’s likely the big-swinging catcher. This prop is among my best MLB expert picks today.

4. Game Prop: First 5 Innings Under 4 Runs (-115)
With two strong starters and both teams struggling out of the gate (Cleveland averages just 1.4 runs through the first three), the early innings should be quiet. This prop also provides a hedge in case the bullpens get leaky late. It complements the full-game Under while still cashing if one arm fades after the fourth inning. It’s a safe addition to any MLB same-game parlay picks.
