It's a stretch to read "tension," as the subject line of this thread suggests, into the reporting. Those who believed Kepler should have taken second base are confirmed, both manager and player agree about that at least for public purposes, and that's about the substance of it.
When someone is known for not throwing his players under the bus, it can have extra impact when he does speak in a negative way about that player's performance in a particular game. It's possible to read more into it than that, but risky.
