WASHINGTON -- With his cheeks looking much puffier than normal, a fatigued Tim Hudson returned to Nationals Park late Saturday morning and said he had only himself to blame for the cramping and dehydration that forced him to exit Friday night's 7-4 win over the Nationals.

More importantly, Hudson said he will be ready to make his next start. The Braves' veteran pitcher is on schedule to start Wednesday's regular-season finale against the Phillies. But if his team has clinched the National League Wild Card entry at that point, he will likely start Game 1 of the NL Division Series.

"Everything is fine," Hudson said. "It's just one of those things where I got exhausted and dehydrated. It's frustrating, because I know it's my own fault."

Hudson went to a local hospital after exiting Friday's game in the sixth inning and received five bags of fluid. He did not return to his hotel until around 3 a.m. ET and found it difficult to sleep with the fluid running through his body.

Hudson has been occasionally bothered by cramping and dehydration during his career. He has often felt the cramping in his legs and right forearm. During Friday's game, he felt cramping between his right shoulder and neck.

"I didn't prepare before the game like I should have, as far as hydrating and stuff like that," Hudson said. "I thought we were going to have a long [rain] delay."

It seems Hudson was a victim of weather forecasts which predicted temperatures in the low 70s and a strong possibility that the Braves and Nationals would have to wait through a long delay before starting their series opener.

Shortly after eating around 5:30 p.m. ET, Hudson learned the game was going to start about five minutes later than originally planned. As he rushed to get ready, he opted not to receive the fluids he often gets via an IV before games.

Hudson felt he would be fine with the temperature in the low 70s. But he was not prepared for the humidity at the ballpark after the rain ended.

"I didn't feel so good last night after the game, but I'm OK now," Hudson said.

Medlen can pitch way to potential playoff roster

WASHINGTON -- Three weeks ago, it seemed Kris Medlen might have to wait until next year to rejoin the Braves' pitching staff. But as the regular season nears its close, it appears the right-handed reliever could be a part of the club's potential playoff roster.

The Braves activated Medlen from the 60-day disabled list before Saturday afternoon's game against the Nationals. The 25-year-old has been sidelined all season while recovering from Tommy John elbow reconstruction surgery he underwent in August of 2010.

Medlen will attempt to fortify a bullpen that no longer possesses right-handed reliever Peter Moylan, who may need to undergo major surgery on his right shoulder. An MRI exam performed Thursday showed he has tears in his rotator cuff and labrum.

During the early portion of September, Braves general manager Frank Wren informed Medlen that he would be given a chance to complete some innings in the instructional league and then possibly be eligible for the playoff roster.

Medlen passed the test and will now have a chance to make a couple of appearances with Atlanta before the regular season concludes. He posted a 3.04 ERA and held opponents to a .250 average in 17 appearances as a reliever last year.

To make room on the 40-man roster, the Braves designated outfielder Matt Young for assignment. Young began this season on Atlanta's Opening Day roster, but he spent most of the year with Triple-A Gwinnett.

Gonzalez gets another day to rest calf strain

WASHINGTON -- If the Braves had been in a desperate position, shortstop Alex Gonzalez likely would have been back in their lineup for Saturday afternoon's game against the Nationals.

But with a three-game lead in the National League Wild Card race and five games to play, Gonzalez was given another day to rest.

Gonzalez felt just a little discomfort as he tested his strained right calf while running in the outfield at Nationals Park on Saturday morning. It appeared the Braves will be prepared to put him back in the lineup for Sunday's series finale.

Gonzalez has been sidelined since exiting Tuesday night's win over the Marlins with the calf strain he suffered a few days earlier. The ailment did not affect him at the plate -- he has batted .467 with three homers in his past eight games.
