With respect to Naquin, it's more than just a 40 game sample. Naquin blew out his knee on July 30, 2019. He had surgery and rehabbed all winter. In March he was doing drills and taking batting practice but was not ready to face live pitching and did not play in any games before spring training was cancelled.
In July he was ready to go and participated in the abbreviated three-week "spring" training but fouled a pitch off his foot in an exhibition game against the Pirates, resulting in a hairline fracture that caused him to miss the first 17 games. He didn't actually play in a regular season game until mid-August, over 12 months after his knee injury.
So I'm willing to give him a mulligan for this year, or actually one-fourth of a year after not playing for over a year. If he can spend this off-season doing baseball activities followed by a normal spring training I don't see why he can't put up the same numbers he did in 2019 which would be a big improvement over every outfielder we trotted out last year at a very reasonable cost, probably under $2 million.
In the two season where he's had at least 274 at-bats his OPS was .886 and .792. When he's been healthy and playing every day against righties he hits. Yes, he is an injury risk and he doesn't hit for power and he doesn't walk, but considering his salary ($1.5 M base last year) I think it's a worthwhile risk. But I won't jump off a cliff if they decide to move on. They eventually gave up on Chisenhall staying healthy and this could be the year they give up on Naquin.
