Observations from Yankees spring training on Friday, a 4-2 win over the Tigers at Joker Marchant Stadium in Lakeland, Fla.

Jameson Taillon struggled with his command — walking three — but he tossed 2 ⅔ more shutout innings. He’s now unscored upon — and struck out nine — in 5 ⅔ innings this spring.

While Jay Bruce continues to hit, Derek Dietrich — another lefty-swinger with defensive versatility — continues to struggle. Dietrich started at second base, but went 0-for-2 with a strikeout and is now 1-for-10.

On the day Austin Wells was assigned to minor league camp, the catcher still made an impression at the plate, with a hard comebacker that Detroit’s Erasmo Ramirez managed to get a glove on.

Corey Kluber will be on the mound as the Yankees host the Pirates at Steinbrenner Field in Tampa at 1:05 p.m.
