Starting pitching -- it all starts with starters.
Doesn't matter if you're a contender looking for a championship boost, or a cellar-dweller beginning a rebuild.
Red Sox major mound additions that eventually led to rings (pitchers specifically recruited to fortify playoff rotations): '04 Schilling, '06 Beckett, '10 Lackey, '17 Sale.
But most relevant to the 2024 Sox may be the biggest and best acquisition: Pedro Martinez in '98. Boston was coming off a losing season with a 78-84 record -- identical to the '23 Red Sox -- when Dan Duquette swung a trade for the 26-year-old NL Cy Young winner. Pedro instantly catapulted the Sox to 92 wins, back into the playoffs, and changed the culture for decades.
Bad teams simply cannot wait until they're somehow good again before investing in really good pitching. A top of the rotation starter changes everything: giving the D confidence, taking the pressure off his O, resting the bullpen, easing stress for management, and from the business standpoint -- exciting the fanbase, sparking a buzz through the media, and making the host city more appealing for future free agents.
