Padres vs Giants Pick

This is a tough slate. As of this writing, nearly 11 pm ET, we’re still missing four pitchers, while three games have no market at all. Just a few games are even offering strikeout props.

On top of all that, what does exist for Saturday is fairly tight, but I couldn't stop at just two games, so I’ll be leaving you with a lean for a Saturday afternoon game.

Some people seem to think Michael King has completely rebounded with a 3.00 ERA this year.

With a career-worst 11.4 K-BB% that includes his relief years and no single estimator below 4, I tend to disagree.

While King’s 33 Hard% is very strong and within a point of his career average, his 8.4% Barrels/BBE is the second highest of his career behind last year’s 11.4%.

King’s success is predicated on a career-best .251 BABIP and 82.1 LOB%. He’s been much closer to around four and a third runs per nine, a number BARTOLO appears to agree with.

We don’t know much about his opposition, Cesar Perdomo, making his third major league appearance and second start. He didn’t even reach 50 innings at AAA.

Perdomo is a non-prospect, ranked 41st in the organization by Fangraphs with a 35+ Future Value grade. A 60 grade changeup is his only above-average pitch.

A 22.6 K-BB% in 72.1 AA innings this season is impressive, but dropped to 7.5% at AAA.

However, he does have a 17.1 K-BB% and an acceptable 40 HardHit%. Pitch modeling likes the changeup (56 PitchingBot, 115 Pitching+).

There is some conflict between his 5.52 Bot ERA and 96 Pitching+, but I’ll accept BARTOLO’s 4.59 projection with a range between 4.49 and 4.70.

That would only put him about a quarter run behind King.

The projected San Diego lineup averages a 101 wRC+ against RHIP (just .144 ISO), 102 wRC+ on the road and 102 wRC+ over the last 30 days. Looks like a league-average offense to me.

The San Francisco projected lineup (and I’ve swapped out Knizner for Cavanaugh) averages a 101 wRC+ against RHP (.139 ISO), 85 wRC+ at home and 102 wRC+ over the last 30 days.

Rafael Devers has a 133 wRC+ at home, 175 wRC+ and .326 ISO vs RHP and 208 wRC+ over the last month.

Bryce Eldridge has a 139 wRC+ at home, 121 wRC+ and .177 ISO vs RHP and 166 wRC+ over the last month.

These two hitters make an otherwise empty lineup slightly formidable.

Defensively, the Padres project a whopping 39 FRV ahead of the Giants on Saturday, and I’m not even going to bother considering bullpens.

I don’t believe the offenses are as close as the numbers quoted above. BARTOLO has them separated by 7 points of wRC+ vs RHP. Guys like Tatis and Merrill were so bad in the first half that their season numbers probably don’t accurately portray their true talent, even with breakout second halves. Bogaerts may be toast, unfortunately.

And I tend to hold out for a larger value flag when dealing more with pitcher projections than performance at the major league level, which is why I’m keeping this as a lean at a number I would otherwise normally play (F5 +126 FanDuel).

I would need at least +130 in this spot.

Mariners vs Athletics Pick

On the surface and even underneath the hood, Bryan Woo has posted another strong season. His 19.8 K-BB% may be behind last year’s breakout, but still the second best of his career.

His 4.03 ERA is about a half run above a tight set of estimators ranging from a 3.34 FIP to a 3.69 dERA, and his pitch modeling (3.06 Bot ERA, 113 Pitching+) is best on the board Saturday, among confirmed pitchers.

Woo’s 66.1 LOB% is 7.6 points below his career average, and even his .273 BABIP ties for his career worst in his rookie season.

But then, there’s also home Woo and road Woo. The latter, who we're getting here, has a 7.8-point lower K-BB (16.2%) and a full run higher xFIP (4.10 to 3.11).

Batters have a .212 wOBA against Woo in Seattle, including a .102 wOBA for 109 RHBs, but a .337 wOBA against him on the road, with batters from either side of the plate within four points of that mark. Twelve of his 18 home runs have been surrendered on the road in fewer than four more innings.

And Woo hasn’t even pitched in Sacramento yet this year.

A wrecked Sacramento projected lineup includes just a single batter (Zack Gelof 106) above a 100 wRC+ against RHP this year. They average just a 77 wRC+ and .133 ISO against RHP, though a bit better at home (94 wRC+).

There’s nothing I can do to pretty up the numbers, unless I substitute the wrong Max Muncy, and even then… it’s still ugly.

However, the Seattle defense behind Woo (or at least the projected one) has been awful, sitting at -20 FRV, even a run worse than the A’s projected defense, and the bullpen, while ranked BARTOLO’s 6th best, has the worst ERA in the league over the last month (7.16), supported by a 5.34 FIP, allowing 1.9 HR/9.

The xFIP (4.01) and SIERA (3.76) are more middle-of-the-league, but the three indicators averaged out put the Mariners in the bottom third of the league over the last month.

If home runs are your problem, Sacramento is the last place you want to pitch.

Gage Jump is a volatile (5.12 ERA, 10.6 BB%), but exciting young pitcher (24.9 K%, 6.6% Barrels/BBE).

He has six quality starts, all with two runs or less. He’s struck out at least seven in eight of his 19 starts.

He’s also allowed at least four runs in no more than five innings eight times and struck out five or fewer 10 times.

Jump has sat below 96 mph in seven of 19 starts, but also 97 or better five times. His last four starts have been two of each.

Sometimes volatility is what you want, especially in a sizeable dog.

BARTOLO projects four left-handed Mariners for Saturday, but that’s not really an issue with batters from either side of the plate sporting a wOBA and xwOBA between .319 and .338 against Jump,

However, the projected Seattle lineup as a whole is averaging just a .131 ISO against LHP this season. On the road, against LHP and over the last 30 days, they’re averaging between a 100 and 104 wRC+ for each.

As mentioned above, the projected A’s defense has accumulated -19 FRV, but while BARTOLO ranks the bullpen 29th in the league, they actually have the 6th best estimators over the last 30 days with a 2.84 FIP, 3.88 xFIP and 3.76 SIERA. In contrast to Seattle, the Sacramento bullpen has allowed just 0.2 HR/9.

Unsustainable, but they’re pitching half their games in Sacramento while doing this!

With defenses and base running both washed, I still have Woo two-thirds of a run ahead of Jump, but the volatility is good news with this price, and Woo is lesser than his whole on the road.

I’m not going to force an offensive comparison, but bullpens are interesting. It’s a 23-team gap for BARTOLO’s season numbers, but nearly a full run gap going the other way over the last 30 days, almost all based on home runs, and I think I’ve emphasized where they’re playing enough here.
