Red Sox sign Dodgers World Series hero Walker Buehler to $21 million contract

The Red Sox’s rotation makeover continues.

Boston signs Dodgers postseason hero Walker Buehler to a one-year, $21.05 million contract that includes $2.5 million in performance incentives, according to ESPN.

Boston set out this offseason to upgrade a rotation that ranked No. 17 with a 4.04 ERA, and the unit is clearly better after adding Crochet and Buehler.

The Red Sox now have to hope they receive the Buehler who pitched in the NLCS and World Series and not the Buehler of the regular season and NLDS.

Returning from his second Tommy John surgery last season, Buehler went just 1-6 with a 5.38 ERA spanning 16 starts. He posted a career-low 7.6 strikeouts per innings.

His first postseason start did not go well, with Buehler allowing six runs in five innings in a loss to the Padres.

But then it changed.

Buehler shut out the Mets over four scoreless innings in Game 3 of the NLCS, shut out the Yankees over five innings in Game 3 of the World Series and recorded the title save in Game 5.

He gave up just five hits in 10 innings while striking out 13 spanning those three outings.

Buehler is apparently hoping he can have a strong year in Boston and then cash in next offseason when he doesn’t have the stink of a 5.38 ERA attached to him.

But pitching in the AL East, facing the Yankees, Blue Jays, Orioles and even the Rays and having Fenway Park as his home stadium, could work against him.

Boston is now set to start Crochet, Buehler, Tanner Houck, Brayan Bello and Lucas Giolito after last season’s 81-81 finish.
