Sunday Night Baseball returns as the San Diego Padres go for the road sweep of the Seattle Mariners at 7:20 p.m. ET on Peacock.
With the series wrapped up, the Padres might come out sluggish. I’m bullish on three Seattle Overs with my Padres vs. Mariners props and MLB picks for Sunday, May 17.

Padres vs Mariners player prop picks
George Kirby Over 5.5 strikeouts (-108)
The Seattle Mariners have to be thrilled with what they’ve gotten from George Kirby in 2026.
After a relatively ineffective and injury-plagued season in 2025, "Furious George" is in the Top 10 in innings thrown (57) and wins (five) among starting pitchers.
This is a spot for the San Diego Padres to underperform. They’ve already wrapped up the series by taking the first two on the road, and are looking ahead to tomorrow’s crucial matchup with the Los Angeles Dodgers, who enter Sunday a half-game ahead of the Friars in the NL West.
The Padres haven’t been excellent against right-handed pitchers even when dialed in, posting the second-worst wRC+ (74) and fifth-highest K-rate (24.9%) this month.
Kirby pitches deep into games, averaging 6 1/3 innings per contest. If he goes that long, his ability to control the strike zone (92nd percentile chase rate, 83rd percentile walk rate) makes him a strong candidate to rack up Ks.
Randy Arozarena 2+ hits + runs + RBI (-110)
Lucas Giolito returns to the big leagues for his debut with San Diego. Given his 5.01 xERA across 26 starts in 2025, the Seattle lineup should be licking its collective chops.
The husky hurler showed reverse splits a year ago, surrendering a 1.40 WHIP to right-handed hitters. That’s a continuation of what he’s done for most of his career (4.60 FIP), so it’s fair to boost projections for all of Seattle’s righties.
Randy Arozarena’s 148 wRC+ is the highest he’s recorded since 2020. He’s destroyed right-handed pitching, slashing .318/.414/.450 with a 155 wRC+.
Julio Rodriguez 2+ total bases (+100)
Last we saw Giolito, he operated with a three-pitch mix of four-seamers, sliders, and changeups. This is music to the ears of Julio Rodriguez, who has feasted on all three offerings.
J-Rod has strong results against four-seamers (164 wRC+) and sliders (122) while positively demolishing changeups (282). He hasn’t been able to find success against any other pitch type, posting a wRC+ below 100 for all other offerings.
Add that to Giolito’s aforementioned reverse splits, and this is a dream matchup on paper for Rodriguez.
