I noticed in the Sunday boxscores from the Venezuelan Winter League that Tyson Gillies was removed for a pinch runner today in the 6th or 7th inning. He is their leadoff hitter and probably the fastest guy on the team so why would they pinch run for him? After doing a little research I found an article in Spanish that said the following about Gillies:
“Leve tirón en cara posterior del muslo izquierdo. Sin consecuencias graves. Retirado del juego por prevención.”
A loose (online) translation of the above shows:
“Light pull in posterior face of the left thigh. Without serious consequences. Retired person from game for prevention.”
The description doesn’t sound serious but with Tyson’s history of hamstring injuries the past 3 years, it could be cause for concern. Afterall, he is considered by many to be the frontrunner for the centerfield job with the Ironpigs in 2013. Hopefully it does turn out to be just a minor tweak.
Here is the original tweet:

For now it looks like all is well with Tyson Gillies and yesterday was just a precaution. So far, the Phillies prospect who was acquired from Seattle in the Cliff Lee deal (along with Phillippe Aumont & J.C. Ramirez), is 7-15 .467 in Venezuela. His 3 walks in 4 games puts his on base pct. at .556. Very good numbers for a leadoff hitter!
