But with eight games remaining in the White Sox push to the postseason, an upbeat Johnson realizes there might be more heroics to come.
"You got to start small, you know what I'm saying," said Johnson, who drew a two-out walk against Chris Perez on Tuesday to extend the ninth inning in an eventual 4-3 loss. "If it comes down to the last strike of the season, there's somebody who likes to do that kind of stuff, likes those situations. That's the way it is. It worked out.
"Obviously, you've got to get runners on to score. And obviously [Adam Dunn] came up with a big hit during that inning."
The 33-year-old veteran knocked out 28 homers and drove in 85 for Triple-A Charlotte, but did not get a call to the Majors until September. Much like the White Sox, Johnson simply focuses on what he can do on a given day and not the past or the future.
"I'm telling you, in this game, if you dwell on anything, any negativity, it's going to affect you at the plate, it's going to affect you in the field," Johnson said. "This game is too much of inches to let anything get in your mind.
"This is the way I look at it. There are nine games left and we got to make it to the playoffs. Everything else in the past is past. It doesn't matter what you've done for me lately. It's got to be right now."
