My analysis

The Philadelphia Phillies are certainly going through it. A loss on Saturday made it six straight without a victory and moved them to 3-11 since the All-Star Break. They’ll look to break the slump on Sunday with a projected pitchers duel between Zack Wheeler and Logan Gilbert

While Wheeler gives his team a great shot, it’s difficult to feel good about the lineup behind him. They’ve fallen apart, posting the second-worst wOBA (.263) and wRC+ (67) against RHP since the Break. 

Gilbert has been a joy to watch this season and has a pretty 3.11 ERA, 3.22 xERA, and 3.33 FIP heading into this matchup. He’s looking to bounce back after a blow-up spot his last time out, surrendering seven earned in just 2 2/3 IP at Boston. 

There are reasons to think he’ll get right back on the horse. He’s been superb at T-Mobile Park, holding opposing batters to a .191 BA and .233 OBP while posting a 0.86 WHIP. 

The weather forecast sets up well with winds of 4.7 mph blowing in toward the third base dugout. 

Gilbert should have a fine leash after throwing only 69 pitches in his last outing. With the Phillies being so ineffective at the plate lately and this one projecting as a pitcher’s duel, one anticipates him pitching deep into the game. 

What does that mean? I’m betting that it results in more strikeouts. 

The 27-year-old has bumped his swinging strike rate up two percentage points from a year ago to 14.3% and ranks in the 84th percentile in whiff rate (30.1%). The punchouts are there to be had against a Philadelphia team with a 24.1% K rate against RHP since the Break.

Gilbert has thrown 7+ strikeouts in three of his last four starts and I’m betting on him to do so again against a floundering Phillies team.

Phillies vs Mariners same-game parlay (SGP)

Logan Gilbert Over 6.5 strikeouts

Zack Wheeler Under 7.5 strikeouts

Mariners moneyline

Wheeler’s K prop is typically listed at 6.5 but the books have bumped it up to 7.5 in this matchup. Seattle has a reputation for being a punchout machine at the plate, especially against RHP, but that hasn’t been the case lately and the lineup was remade by the trade deadline.

Seattle has a 21.8% K rate against RHP at home since the Break and has made pitchers work through counts, posting the third-highest walk rate (11.7%). That’s a vast improvement to what they were doing previously, and I don’t think the books have corrected quickly enough.

Since I’m betting on Gilbert having a fine outing and Seattle’s lineup is a tad undervalued in the betting market, it’s certainly no gimme that Philadelphia breaks its six-game losing streak.
