MLB Game Overviews

San Francisco is at 130 wRC+ over their last 6 vs RHP and 143 over their last 12, elite in both windows, and they face a staffing plan built out of relief innings: Lake Bachar opens after averaging 1.9 IP over his last five outings, with Mlodzinski behind him carrying a 4.70 xERA and last two starts of 2.1 IP with 4 ER and 3.0 IP with 4 ER. Mlodzinski also worked out of the bullpen on Sep 2, and the Pittsburgh pen is already at 9.3 relief innings over the past two days, so the middle innings come from tired arms in a 90-degree PNC Park. The counter is San Francisco's 3.0 runs per game average on the road behind this starter, but that is a four-start sample against an offense hitting at this level in both recent windows. Four runs is priced near a coin flip against a bullpen game the Giants are equipped to run up.

Castillo is averaging 3.8 IP per start over his last 3 and has not reached the fifth inning in any of them — 4.2 IP, 2.2 IP and 4.0 IP, the last one on just 75 pitches. His 7.49 xERA and 49.1 HH% over that window explain why the hook comes early: eight hits allowed in each of two of those three outings. Houston's 60 wRC+ over their last 6 vs RHP is the one thing that could buy him length, but he was pulled at 75 pitches with a cold Minnesota lineup on Aug 28 and he lasted 4.8 IP per start across three career meetings with Houston. Laying juice buys a number his own recent starts have never touched.

Young is carrying a 14.5 K% with a 16.5 Whiff% over his last 3 starts, and the strikeout totals match: 3, 3 and 4, never more than four. Boston strikes out at 23.8% over their last 6 vs RHP, up from 20.1% over their last 12, which is the one thing pushing his number up — but even lifting his rate several points against them leaves roughly four punchouts across the 22-23 hitters an outs line of 17.5 implies. He went 7.0 innings on 91 pitches in Baltimore's last time out and still only got four. Plus money on a pitcher whose bat-missing profile projects under four strikeouts is the mispricing.

Wacha has a 25.7 K% with a 24.1 Whiff% and a 1.4 BB% over his last 3, and the totals are climbing — 3, 6 and 10 strikeouts, the last of those over 8.0 innings on 103 pitches. Miami is the right lineup for it: 25.8 K% over their last 6 vs RHP with a 28.0 Whiff% behind it, both up from 22.3% and 24.3% over their last 12, so the swing-and-miss is real rather than a sequencing artifact. The outs line of 18.5 is the argument against — the market expects him back under six innings after that 103-pitch outing — but with almost no walks he faces 24 hitters in six innings and needs one strikeout per inning at a lineup missing better than a quarter of its swings. Plus money on a number his rate clears in an ordinary start is the value.

Perkins has not completed more than five innings in any of his last three starts — 3.0 IP on 70 pitches, 5.0 IP on 97, and 5.0 IP on 80 — so 15 outs or fewer has been the outcome every time out. A 17.5 BB% over those last 3 is what caps him: he walked four in 5.0 innings against Baltimore on Aug 29 and his pitch count climbs faster than his innings do. Seattle's 28.4 K% over their last 6 vs RHP does give him a path to quick innings, but even his cleanest recent outing ended at exactly 15 outs. The market has this as a coin flip when his own recent workload says the fifth inning is his ceiling.

Skubal's last three strikeout totals are 7, 11 and 7, and the 11 came against Pittsburgh at a 34% team K rate with Detroit at 32% behind it — his recent numbers were built on the two most strikeout-prone lineups he could draw. St. Louis is the opposite: 21.7 K% over their last 6 vs LHP with a 16.9 Whiff% that does not support even that, so the contact quality is there to hold the count down, and their 150 wRC+ over the last 6 vs LHP means traffic and longer innings rather than free outs. Over six innings against 24-25 hitters he projects around seven punchouts, and clearing 8.5 has happened once in his last three against far easier strikeout matchups. The juice buys a number that requires his best outing against the worst lineup he has faced for it.
