Starting on Aug. 9, the Red Sox had been successful in 37 straight stolen-base attempts entering Wednesday action.
"As long as we don't get thrown out, it could be a big edge," Farrell said. "I think that's the one thing that shines through is that typically, you don't associate a running team with a high-scoring team and yet we've been able to do it.
"There were times in July, we kind of ran into some outs and we shut it down for a little while to be a little bit more smart about it and not give away outs on the basepaths. Since then, our guys have paid attention to some situations inside a game where we've been able to exploit.
"And it hasn't been just the top three guys. It's been [Will] Middlebrooks, it's been [Jarrod] Saltalamacchia, it's been guys you wouldn't necessarily think of as basestealers and yet we've been able to capitalize on some of those situations."
When you are that successful in stealing bases, a lot goes into it. Farrell credits the behind-the-scenes work of bench coach Torey Lovullo, first-base coach Arnie Beyler and third-base coach Brian Butterfield.
"Our guys pay attention," Farrell said. "They pay attention to the work that Torey, Butter and Arnie have done to give us maybe a little bit of an advantage or a situation we might be able to take advantage of. And they've been spot on with their timing and when we feel like we've got a chance to take a bag, to their credit, they've trusted it. And that's probably the most important thing. They've trusted the information we give them or our coaches have given them, and they've been successful."
