The six best left-handed hitters I ever saw were Boston Red Sox great Ted Williams, Tony Gwynn, Rod Carew, Wade Boggs, Stan Musial, and Tony Oliva. The common thread, aside from being left-handed, is that they are in the Hall of Fame and did not hit left-handed pitching as well as they did right-handed pitching.
A significant incentive for the Red Sox to sign Alex Bregman was his right-handed power, especially at Fenway Park. With a lefty-loaded lineup, managers like balance, and that is precisely a quality Bregman brought to Alex Cora's lineup card.
The Red Sox's top two prospects — Roman Anthony and Marcelo Mayer — have finally arrived, and Rafael Devers has departed.
