The bad news is, neither he nor Giants head trainer Dave Groeschner knows what the immediate -- or not-so-immediate -- future holds.
The current plans dictate Lowry throwing every other day while taking the weekends off. The lefty, who led the Giants in wins last season, threw 25-30 pitches from about 50 feet Wednesday -- numbers Groeschner said will increase in the coming weeks.
Lowry reported no day-after pain, saying the numbness and tingling he felt earlier in the season has disappeared. That's a positive sign that his surgically repaired left forearm is finally healing, Groeschner said. Lowry was diagnosed with exertional compartment syndrome in early March after several wild starts in Spring Training.
"I feel good, [the ball] was coming out good," Lowry said. "As far as a timetable, I don't have a timetable. I'm hoping and praying and giving it everything I got on my end."
When his teammates hit the road for a six-game road trip on Monday, Lowry will head to the Giants' Minor League complex in Scottsdale, Ariz., to continue his rehab.
Typically, Groeschner would determine a return date for Lowry, but because this situation "has been kind of different, it's something we'll continually judge."
In March, the Giants believed Lowry would be out only two to three weeks. Four months later, it seems likely Lowry will miss the entire season. The projected No. 3 starter, Lowry could have been a boon to San Francisco's rotation -- he won 34 games the past three seasons.
That Lowry hasn't recently felt pain in his arm is encouraging, but he and Groeschner acknowledge that the rehab process must be handled with caution.
"We'll continually be careful," Groeschner said. "We don't want to take any steps backward at this point. Obviously we want Noah back, but my job is to get him back healthy. As you map things out, it looks good, but you never know where the next speed bump is."
