It just makes sense. If a power-hitting catcher no longer has to spend half his time catching, shouldn't his hitting improve?Through the first four games of the season, Jorge Posada is pounding that into reality. The former catcher turned full-time DH is crushing balls out of Yankee Stadium, part a historically powerful attack through its first few games.Posada hit his third home run of the season Monday, and Alex Rodriguez hit his second of the year to power the Yankees past the Minnesota Twins, 4-3. For the third straight night, the Yankees set the all-time lowest attendance mark at their new stadium, with 40,331 on hand.Along with Mark Teixeira—who just missed his fourth homer of the season Monday—the Yankees are riding the homer to victory. The nine homers the Yankees hit through their first three games set a franchise record.The power has helped them overcome mediocre pitching, and Ivan Nova delivered more of that Monday. The Yankees' fourth starter pitched six decent innings, allowing three earned runs, before turning the ball over to the lockdown bullpen.Posada, 39, has been no more than a 20-home run man since 2003. But with his transition to designated hitter, he spends more time focusing on his at-bats, and it's paying off."It's still new. I'm just getting ready for those four at-bats," Posada said.Daniel Barbarisi
