The read
Fenway settles in under a warm, partly cloudy sky, the Monster looming over a Diamondbacks club trying to shake off last night’s beating. Boston has another chance to dictate the game from the first trip through the order.
I’m attacking Merrill Kelly’s weakest lanes. His fastball and cutter have been hit hard, his command has deteriorated, and left-handed hitters have punished him all season. Wilyer Abreu is scorching the ball, Jarren Duran is back, and Boston’s lineup is built to turn Kelly’s traffic into a multi-run inning.
Arizona counters with a diminished, right-heavy order missing Ketel Marte and Nolan Arenado, which is exactly the shape Ranger Suárez handles best. The bullpens are good enough on both sides that I don’t want to lay -159 and sweat a one-run finish; if Boston controls this matchup as expected, I want the plus-money payout on the margin.

LActual 0
Abreu is the Boston bat I want against Merrill Kelly. He owns a 1.292 OPS with five homers over his last 15 days, and Kelly has allowed a .889 OPS and 17 homers to left-handed hitters. Kelly's fastball and cutter have both been hit hard, giving Abreu multiple paths to clear this with one extra-base hit.

Kelly has issued 11 walks across his last three starts and has gone over this number in six of his last eight. Boston can make him work: Sogard, Abreu, Contreras and Rutschman have all been drawing walks regularly, and Kelly cannot afford to challenge the heart of this order carelessly at Fenway.
