I'm far from an expert on modern metrics. Yesterday, I commented that I thought Gilberto Celestino had gotten a disproportionate number of hits on soft contact. According to BBRef, it sure looks like he's been extremely fortunate. Celestino's BABIP (batting average on balls in play) is an incredible .477. Last year, in an equivalent number of plate appearances, that number was .140. Exit velocity this year is 83.9, last year was 87.2. Hard hit percentage this year is 28.9%, last year was 31.1%. Line drive pecentage is the same as last year--24.4%. Celestino's ground ball percentage is 55.6% (really high), compared to 46.7% last year.
I presume that Gilberto was very unlucky last year and in his 67 plate appearances he has made up for that misfortune. It seems to me that Celestino has growing confidence and he shows in the field, but he seems due for regression. As a guy who makes contact and uses the whole field, I doubt he goes into a severe funk, but I don't think he's a .300 hitter and he hasn't shown much power. My thought that Celestino is a fourth outfielder at this point really hasn't changed despite the really good numbers so far.
