"It feels 10 times better today," Bay said. "It's the most marked improvement. It was never bad to begin with."
But it was just bad enough that Bay felt like he should shut things down before making it worse.
"It's kind of those - ok, it's kind of tight now and it could be a couple days now or a couple weeks later," he said.
Bay felt the hamstring tighten up as he was running to first in Sunday's loss in Oakland. But didn't think much of it at the time.
"You don't notice it at the time because of adrenaline and everything, but with the flight and you come here and you wake up the next day, man that's stiff," Bay said.
Bay joked that his age hasn't helped matters.
"Almost 35 doesn't recover quite as fast as 25," he said.
Bay doesn't think the he'll be available to pinch hit. He can swing the bat. But it's the running after he swings that is a problem.
"The problem with them that is if I could guarantee you I could swing and take it easy out of the box," he said. "I can't promise that. I don't know if anyone can do that. You hit a high chopper and you try to beat it out for a hit to help the team, that would be the best worst thing for it."
Statistically, Brendan Ryan hasn't been as good defensively at shortstop this season. He's committed nine errors this season, equaling the total he committed all of last season. His UZR rating is currently -1.9. Last season he finished with a 13.8 UZR.
So what's the issue?
"I think he's been at times he's been overly aggressive and I think at times he's sat back a little bit," Wedge said. "One of his greatest attributes is reading the baseball and having a good tempo. I think he's been better though the last three or four days. He just went through a little funk there."
