Cubs limp into Fenway with David Peterson on the bump and that's your ballgame right there

The Cubs roll into Fenway on Friday night carrying David Peterson and his bloated 6.09 ERA like a suitcase full of bricks. That's not a typo—Peterson's been getting shelled all season, posting a 1.65 WHIP that screams "please tee off on me." Across the diamond, Brayan Bello isn't exactly Cy Young material at 4.49 ERA, but compared to Peterson he looks like prime Pedro Martinez. That's a 1.6-run ERA gap, folks, and in a sport where margins are razor-thin, it might as well be the Grand Canyon.

Chicago does swing it marginally better as a team (.251 versus Boston's .246), but good luck capitalizing when your starter can't get through the fifth without a meltdown. The Red Sox get the Fenway boost here too—home teams win 54% in MLB, and that edge matters when you're catching a wounded opponent.

DarkHorse likes Boston at -102, essentially a pick'em price that undervalues the pitching mismatch and home cooking. The market's giving you Red Sox at implied 50.5% when the reality probably sits closer to 53-54%. Not a mortgage-the-house play at 2/5 confidence, but Peterson's peripheral disaster makes this a lean worth backing. Take the Sox and don't overthink it.
