This alignment makes a lot of sense since Devers would still get the most AB's (vs RH'ers). Nunez gets off his feet/knees for a couple days at a time. Can Holt sit on days Price pitches so the 1-4-3 DP won't risk Holt on a throw from Price, assuming David can handle the ground ball.
Not a Swihart cheerleader , but I wonder how many guys out there who have not played meaningful MiLB nor MLB games at catcher in 3 years can step in with very few reps and handle the mental and physical aspects of a MLB catcher ? Not many. It takes smarts, strenth, versatility, quick thinking, pitcher and hitter knowledge (with bench help), a good arm and oh BTW, you are expected to hit also. Swihart gave up an entire season due to his unfamiliarity with the ridiculous quirk known as the LF roll up door at Fenway.
Anyone is free to rip Nunez and Swihart , like I rip Carson Smith, Joe Kelly and Matt Barnes (forget Thornburg now) but right now you are dependent on these sub/scrubs for 2 critical positions 2B and catcher. Just IMO.
Devers learning ( or not) the game at the MLB level reminds us of Shaw and Middlebrooks, plus the seecond year struggles after a quick intro late the previous season of Benetendi and Bogaerts. It will be boom or bust going forward.
