§ 01The analysis
The case for Wells starts on the mound across from him. Roki Sasaki brings a 4.64 xERA over 81.0 innings into Yankee Stadium, and the deeper numbers are worse, not better. His season FIP is 5.40, and the recent form has cratered to an 8.01 FIP across 23.0 innings over his last 5 starts. The bat-missing tools that used to prop him up have slipped too, with both his swinging-strike rate and his 22.7% strikeout rate coming in below his own baseline. Park context is neutral at a 1.00 run environment. The honest risk is Wells himself. He is hitting .155 on the season over 194 at-bats with a 0.51 OPS, and the last 10 games have produced just 4 hits in 26 at-bats. Against right-handed pitching specifically he is at .176 with a 0.56 OPS across 151 plate appearances, and the slider has been a problem, a .105 average in 19 plate appearances with a 43% whiff. Sasaki has also held lefties to a .207 average across 193 matchups. The bet is buying the pitcher's decline at plus money.
§ 02The call
At +115, the number is asking whether Sasaki's 5.40 FIP and 8.01 FIP over his last 5 starts matter more than Wells's .155 season line and 4-for-26 stretch. The pitcher's underlying form is the reason to be here, with the swinging-strike and strikeout rates both trending the wrong way for him. The counter sits right on top of the ticket, since Wells's numbers against righties and against sliders give real reasons to fade. Take the price on the arm regressing at Yankee Stadium.
