WASHINGTON -- The Washington Nationals placed Gio Gonzalez on the 15-day disabled list Sunday because of inflammation in his pitching shoulder. DeMarcus Ware Broncos Jersey . This is the first time the 28-year-old left-hander has gone on the disabled list. Gonzalez (3-4) dropped his third straight start in Saturdays 5-2 loss to the New York Mets. He lasted only three innings, allowing five runs and seven hits, which raised his ERA to 4.62. Gonzalez gave up seven runs and nine hits in his previous start at Oakland. General manager Mike Rizzo said Gonzalez had an MRI on Sunday in which dye is injected. He will not be able to throw for five days. "Hell miss two starts," Rizzo said of the initial plan. "Well find out whats going in (Gonzalezs shoulder) and take it from there." The Nationals recalled Ryan Mattheus from Triple-A Syracuse. Gonzalez left a start in late April because of shoulder tightness. "He passed a strength test. Combined having a little soreness (Saturday) with a little soreness a month ago, we thought this was a prudent way to do it," Rizzo said before Sundays series finale with the New York Mets. Gonzalez side-stepped questions about his health Saturday, but spoke with Rizzo following his latest loss. "I dont have a great concern level for it right now just because the way Gio said he felt after the game," Rizzo said. Gonzalez lost command of the strike zone Saturday, falling behind in the count and throwing 84 pitches in three innings. "I thought he looked fine," said Rizzo about whether he saw an injured pitcher on the mound. "His arm speed was good. His spin was fine. As good as its always been on his breaking ball. His fastball velocity was good. The command part of it, which sometimes comes and goes with Gio anyway, was the thing that was causing him an issue." Gonzalez went 32-16 during his first two seasons with the Nationals after a trade with the Oakland As. He made at least 32 starts in each of his previous four seasons. "Hes a big key to the ball club," Rizzo said. "Wed like to get him back. Were going to take our time with him and be careful with him because hes vital to the ball club." Mattheus has 140 career appearances with the Nationals, including two this season. He has not allowed a run in three innings. Terrell Davis Womens Jersey .
