While checking out some charts on Fan Graphs today, I came across a short post by David Golebiewski titled Spring Training Silliness. Mr. Golebiewski reminds baseball fans that while it's easy to get excited about Spring Training stats, always keep in mind that the sample sizes are extremely small, and the levels of competition from inning to inning can vary drastically. He notes the following player stats to illustrate his point.
Brett Gardner: 3 home runs, .875 SLG% in 24 AB
Career minor league SLG%: .385
Career minor league HR: 9 in 1,456 AB
Rajai Davis: .864 SLG%
Career minor league SLG%:.407
Career major league SLG%: .354
Glen Perkins: 12 IP, 1.50 ERA
Career major league FIP: 4.87
Aaron Cook: 15 K’s in 14 IP
Career major league K/9: 3.58
I tend to agree with the point being made, and would add that up to this point in Spring Training, most of the games have been the equivalent of a basic AA minor league game in terms of overall talent. So, if a 25 year old "rookie" is lighting it up, don't let it sway you. But then again, if you notice any 18 or 19 year olds holding their own against older, more experienced competition, there might be reason to investigate further. Either way, keep it all in perspective.
