Wainwright expects to undergo another round of tests within the next few days to see if he can increase his mobility work.
"I want to be out there taking [groundballs] and running station to station and leading groups and doing all that, too," said Wainwright, whose normal spring program was interrupted by a mid-February abdominal strain. "But each year is different. This year, it's not smart for me to be running around. We're trying to get me ready for April 5."
With the countdown to Opening Day down to 24 days, Wainwright still has ample time to make three spring starts in advance of the regular-season opener, as long as he makes his Grapefruit League debut by the end of next week. Asked if he felt that would be sufficient preparation for another Opening Day assignment, Wainwright grinned.
"I would never tell you 'No,' would I?" he answered. "If I only had two starts, I'd tell you that was plenty. I think there is way more than enough time for me to get ready."
That process includes not just building up his pitch count, but also getting a better feel for his pitches. On Thursday, Wainwright was less-than-pleased with the command of his fastball, two of which center fielder Peter Bourjos squared up. One of Bourjos' hits caromed off the center-field batters' eye.
"It's a good test," Wainwright said. "I love seeing hitters. They tell you what your stuff needs to do. … Today, the goal was to try and start honing in some of those pitches. I did on about 80 percent of them. And I threw some really bad pitches that got hit. Bourjos put a couple good at-bats on me on balls that big league hitters are supposed to hit."
