Matusz missed the first two games of the series against the Toronto Blue Jays with a virus that caused him to spend time in a local hospital Friday afternoon. He had to receive IV fluids and wasn't released until later that night.
"I think that was just to get on IVs, and make sure everything was OK, and make sure that it wasn't a stomach problem," Matusz said. "It was more precautionary."
By Sunday, Matusz said he finally felt better.
"[Sunday] was the first time I got up and walked around, other than going to the hospital," Matusz said. "Sitting at home, watching the team play on TV, there's no worse feeling to go along with having the stomach flu and being sick. Being kind of hopeless like that, it's not much fun."
Matusz returned to game action with one out in the eighth inning Sunday, entering in relief of right-hander Josh Stinson. Matusz walked the first batter he faced before recording two outs. He threw 11 pitches before turning the ball over to right-hander Ryan Webb to start the ninth inning.
"We'll see how Brian feels [Monday]," Orioles manager Buck Showalter said. "That was a lot of unknown there, but there is only one way. You've got to get back on the horse."
Matusz was nearly pressed into action earlier than anyone wanted.
As the Orioles played into extra innings Saturday night, Matusz said he considered going to Camden Yards.
"If the game went a couple more innings [Saturday] night, I was thinking about putting some clothes on and heading over to the field just in case," Matusz said. "Maybe if we got to the 14th or 15th, I would have started talking myself into feeling better than I actually was."
Showalter admitted that he considered making a call to Matusz.
"We didn't have any starters last night that I could do anything with," Showalter said. "So we were down to Matusz if we kept going, one of those 17-inning specials."
Davis' power — and speed
Through his first 11 games of the season, Orioles slugger Chris Davis didn't have any home runs after leading the major leagues with 53 in 2013. That changed in the eighth inning Sunday when he homered to center field against Toronto's Esmil Rogers.
Davis is hitting .279 and tied for the team lead in RBIs with seven. And now his powerful bat has caught up with his feet. Heading into Sunday, the slugger had one steal — second base in the first inning Saturday — and no homers.
"Everybody's talking about whether I can get 53 homers again this year. I'm getting 50 bags [stolen bases] this year," Davis joked.
Davis is 12-for-18 in stolen-base attempts in seven seasons in the major leagues. He set his career high last year with four. His lone steal this year is the club's third of the season; speedy outfielder David Lough has the other two.
"Who is second on the team in steals? This guy," Davis cracked.
Showalter said Davis can steal a base when the opportunity is there — a major asset in a tight game.
"Chris runs the bases well," Showalter said. "If you don't pay attention to him, he's going to steal second. That's quite a weapon. He brings a lot of things like that."
