When Orioles right-hander Ryan Webb tweaked his left knee playing catch on Sunday, and then saw the knee swell the next morning after icing it all day, he was concerned the injury be worse than he initially believed.
But a MRI performed on Webb's knee Monday revealed no structural damage, and Webb said he was given an even more unusual diagnosis, that the swelling was caused by an allergic reaction to ice.
"Apparently icing didn't help me," Webb said.
Webb said he tweaked his ankle playing catch during Sunday's workout, but continued to participate in the workout.
"I was just playing catch and it kind of came up feeling a little funny for a second," Webb said. "I was shaking it out and I finished playing catch. I finished doing the PFP drill and all that and when I came in it felt like I tweaked it a little bit. We took a look at it and I iced it for the rest of the day and the swelling kind of camp up a little big."
Webb was relieved to get a clean MRI result and said he hopes the swelling will go down in a few days and he can return.
"I was worried there for a second because it swelled up pretty bad, but I was thinking I really didn't do anything out there bad to it," Webb said. "I didn't fall. I didn't bang it into anything. It just twisted it a little bit playing catch, so it couldn't have been anything too serious so it's a big relief.
Webb, who was 3-3 with a 3.83 ERA in 49 1/3 relief innings last season, does not have history of knee problems. He's only been on the disabled list once in his big-league career, missing 44 games in 2011 with right shoulder inflammation.
"It's sure it's just one of those freak things," he added. "I'm sure there's nothing I could really done to avoid it. I don't know what happened, if it was a soft patch of grass I stepped in and just kind of caught my cleat the wrong way….Hopefully it will be good in a few days and we'll stay on track."
Webb has pitched twice in Grapefruit League play, allowing one run – it came in the spring opener against Detroit – two innings. He's received praise from Showalter for coming to camp in good shape. He arrived at spring training at 228 pounds, 17 pounds lighter than when he reported to camp last year.
He's competing for an Opening Day roster spot in a crowded bullpen mix. Despite being signed to a two-year, $4.5-million deal before last season, Webb was designated off the 25-man roster and later sent to Triple-A Norfolk after the club acquired left-hander Andrew Miller in a trade with the Boston Red Sox.
Webb rejoined the club when rosters expanded in September, pitching to a 4.05 ERA in the season's final month. He was not on the Orioles' postseason roster in either the AL Division Series or the AL Championship Series.
