Day one of the Luis Castillo experiment is over and the best news is that Roy Oswalt lived through it. Oswalt was hit in the neck with a line drive off the bat of Manny Ramirez in yesterday’s game, but was able to walk off the field on his own and appears to be okay. Castillo, meanwhile, went 0-for-4, hitting the ball hard once but lining out and handling two defensive chances at second.

Yesterday the Phils fell to the Rays, losing 4-1.

Oswalt started the game for the Phillies and went three innings, allowing three runs on four hits. He started the fourth and gave up a leadoff home run to Evan Longoria before Manny smashed a ball back to the mound that hit Oswalt near the right ear. He left the game and was replaced by David Herndon.

Oswalt has now made four starts in which he’s thrown to a 4.61 ERA with a 1.17 ratio. In 13 2/3 innings, he’s walked just one batter and struck out 13.

Herndon threw two scoreless innings and was followed by Mathieson and Bastardo. Each threw a scoreless inning, but Mathieson walked the bases loaded in the sixth. Madson pitched the ninth and allowed a run on two singles and a double.

Mathieson now has a 2.00 ERA and a 1.00 ratio after seven appearances. In nine innings he’s struck out nine and allowed just three hits, but walked six.

The guys in the bullpen have been rather impressive at preventing the long ball this spring. Baez, Herndon, Madson, Mathieson, Zagurski, Contreras, Romero and Bastardo have combined to throw 67 1/3 innings without allowing a home run. Lidge has allowed one in his five innings. Were the bullpen to have that kind of success at preventing home runs over the course of the regular season, they would wind up with some impressive numbers. In 2010, Phillies relievers allowed 37 homers over 421 innings, which would be about 6.4 over 72 1/3 innings.

Martinez was the only Phillie with more than one hit. He went 2-for-4 with two singles. Rollins was 1-for-3 with a double and Orr 1-for-3 with a triple. Barfield again played center and was 0-for-3. Young 1-for-1 and Mayberry 0-for-1.

Hamels faces the Twins today.
