Walker allowed one hit over two scoreless innings without walking or striking out a batter in Saturday's Grapefruit League game against the Nationals.
The one hit Walker gave up came on a sun-aided popup that didn't leave the infield. The veteran right-hander came into camp behind the rest of the Mets starting pitchers after undergoing knee surgery in January, but he appeared healthy Saturday and Bill Ladson of MLB.com reports that Walker believes there's still enough time left in the spring for him to build up to five innings for his first regular-season outing. While he'd likely be on an early pitch count, Walker may be able to slot into the fifth starter spot in the Opening Day rotation rather than having to skip a turn or two.
