Darren Smith tweeted the following a short time ago, so we know it's true:
The Padres broadcast team and San Diego media, I feel, have kinda hammered home the fact that Gyorko and his wife are expecting twin boys. Here he is on Padres Social Hour following the announcement of his contract extension:
When asked how his life will change because of his new contract, he mentions that it'll be nice having security for himself, his wife, and their two boys.
Gyorko's played in every game of the season up to this point, and started in all but one - that makes just seven innings this year that he hasn't played, so he is more than overdue for a little time off to be with his family. In fact, time off might be just what he needs right now. Gyorko hasn't been having the best sophomore season; he's batting just .144 and has an OPS of just .429. He's also made three errors on the year already - half his total from 2013. Having two new Friar Faithful in his life and cheering him on will be great motivation when he returns to the team.
So who will take over his position tonight, and possibly the rest of the series? Alexi Amarista is only other guy on the active roster who has spent time at second base this season, making the start there in the sole game Gyorko didn't start. He is the most probable candidate. Recent call-up Jace Peterson might also be a possibility, though not a very strong one. Even though Peterson has almost no 2B experience, John Sickels thinks his skills would translate to the position.
Tommy Medica, who earned a spot on the 25-man after an outstanding Spring, will probably sit on the bench and be used as a pinch-hitter. He's made 14 appearances (seven starts) this season, accruing four hits and a couple of RBI. Medica was optioned to Triple-A El Paso just a few days ago, but fans will enjoy having him back even if it's only for a day or three, and even if it's just to see his face in the dugout. I'm guessing when Gyorko returns from paternity leave Medica will be sent back down to get some more regular playing time with the Chihuahuas.
