The mood in the Phillies’ clubhouse Sunday was light. As Roy Halladay got dressed postgame, Jimmy Rollins shooed away the herd of reporters, playing the part of PR representative while eating an ice cream cone.

Halladay grinned, even letting out a short laugh. It was a small act, but a telling one considering a man of Halladay’s demeanor. Even after huge wins, Halladay is normally cautious. Quiet. Sunday was different.

Coming into Sunday’s game against the Marlins, Halladay had looked awful in his first two starts. A combined 7 1/3 innings and a 14.73 ERA only added to growing concerns about Halladay’s future as an effective pitcher.

Halladay quieted those concerns Sunday, at least for the time being. He pitched eight innings — more than he did combined in his first two starts — of one-run baseball. He threw just 87 pitches in that span. He only struck two, but gave up just five hits.

Laynce Nix’s upper-deck bazooka of a home run in the ninth put Halladay in line for career win No. 200, making him the 112th pitcher in major-league history to do so. Jonathan Papelbon earned the save, giving the Phillies a 2-1 win against the Marlins and their second series win this season.

The victory makes Halladay the first Phillie to earn his 200th win since Steve Carlton did it in 1978 and the 109th pitcher in baseball history to win 200. Just a couple seasons ago, it looked as if Halladay would cruise to 200. He ended the 2011 season 12 wins away, and had averaged 17 wins per season from 2002-2011. It would be easy, right?

It wasn’t. After a worry-filled 2012, to say Halladay struggled to this point in 2013 would be an understatement. A shaky spring training coupled with an 0-2 record and a 14.73 ERA coming into Sunday had everyone questioning whether Halladay would ever regain form.
