Afterward, Hamels said it wasn't a big deal.
"It's one of those things I kind of don't want to speak [about]," he said. "It's baseball. I don't know him personally, but I do know he's a good guy."
Apparently, Hall does not share the same admiration.
"He's definitely a marked man for me now," Hall told the Houston Chronicle. "So when I do some damage off him, I'm going to let him know I did some damage off him. I can guarantee that."
Hall added that Hamels said "something I didn't like too much."
"I don't feel like I do a lot of things to have pitchers mad at me for doing things on the field," Hall said. "I feel like I play the game the right way. But if you disrespect me, I'm going to do my best to disrespect you back. Obviously not in a way to disrespect the game, but obviously I'm going to let him know when I face him."
The two faced one another again in the fourth, and Hall dumped a broken-bat single into left field.
Another chance for Hall to see Hamels may not come for quite a while. The Astros are in Philadelphia for the first weekend of the season, but Hamels likely will not pitch in any of those games. The Phillies go to Houston in September.
For the record, Hall is a lifetime 3 for 22 with seven strikeouts against Hamels.
Chris Johnson and Jason Michaels also homered off Hamels, who allowed five earned runs in 32/3 innings.
Righthander Scott Mathieson struck out two in a scoreless 11/3-inning outing Monday. After a shaky first Grapefruit League outing, Mathieson has thrown six straight scoreless innings.
He also has been predominantly throwing his secondary pitches - a slider and splitter. On Monday, one strikeout came on the slider and the other on the split.
In fact, Mathieson said, all eight of his strikeouts have come via a breaking ball and not the high-90s fastball that helped him achieve a successful 2010 season at triple A and cult status among Phillies fans.
Mathieson probably won't make the team because of a numbers crunch. He does have an option remaining. But he came to spring training with the goal of demonstrating he has the secondary stuff to make it. So far, so good.
Minor-league pitcher Tyson Brummett entered the game with a one-run lead in the ninth and the bases loaded. He promptly induced a game-ending, double-play ball off the bat of Drew Locke. After the game, Phillies manager Charlie Manuel admitted to not knowing Brummett's name. "I know it now," the manager said, laughing. . . . Rule 5 pick Michael Martinez scored the winning run from second base on a wild pitch.
