№ 03Baty owns a 27.3% barrel rate on right-handed curveballs this season across 17 plate appearances, with 64% hard contact against the pitch.
№ 04Truist Park plays as a 1.10 home run factor for left-handed hitters, with 1050 feet of elevation and 84°F first-pitch temperature aiding carry.

§ 01The analysis
The lead here is López's 4.61 xERA across 51.7 innings. His run prevention has been running ahead of the contact he's actually allowing, and a 4.11 FIP backs up the idea that the underlying work is closer to league average than his ERA suggests. Command is the softer spot: 22 walks in those 51.7 innings, a 3.8 BB/9 that lands in the bottom tier of the league. When López does put a curveball in the zone, Baty has the profile to punish it, carrying a 27.3% barrel rate against right-handed curveballs on the year with 64% hard contact, albeit in a 17 plate appearance sample. The park cooperates too. Truist Park grades as a 1.10 home run factor for left-handed hitters, sits at 1050 feet of elevation, and first pitch is 84°F, all of which push the ball further. The risk is real. Baty is hitting .218 with a 0.60 OPS this season, his 30-day xwOBA against righty changeups is .184 across 13 plate appearances, and López has limited lefties to a .182 average in 121 matchups while running a 20.9% strikeout rate.
§ 02The call
The path to a total base is a walk-happy starter with a 4.61 xERA meeting a lefty who barrels curveballs at a 27.3% clip, in a park that plays 1.10 for left-handed power on an 84°F night at 1050 feet. The counter is the season line, a .218 average and 0.60 OPS, plus López suppressing lefties to a .182 mark. Take the environment and the underlying pitcher quality at -127.
