With respect to the Pacquiao vs Hatton odds, the best clash of the titans in sports to watch right now is probably the Yankees vs Red Sox line. With both teams retooled for 2009 MLB betting, the rivalry should be better than ever. Let’s break down tonight’s matchup and another key National League baseball betting line.

Hard to believe the Yanks and BoSox haven’t met yet this season, but all that will be forgiven when dynamic young starters Joba Chamberlain and Jon Lester go head to head tonight. Chamberlain’s talent is off the charts, but he’s still a work in progress; he has to get over his propensity for nibbling if he wants to go deep in games. He’s struggled out of the gate at the sportsbook and, while he has been successful at Fenway Park in the past (2-0, 3.00), he’s facing the hottest team in baseball as the Red Sox have won seven straight games. Jon Lester is 17-3 at home in his career and loves facing the Bronx Bombers (2-0, 3.42), so he’s a good bet to lead his team to victory tonight.

Online betting pick: Red Sox -130

Phillies vs Marlins odds: Brett Myers (1-0, 5.03) vs Josh Johnson (2-0, 2.91), tonight at 7:10 p.m. ET
MLB lines: Phillies +114, Marlins -134

How are the Marlins only a -134 sportsbook favorite in this one? The matchup screams “Marlins blowout,” as flyball pitcher Brett Myers faces a lineup that specializes in long balls. Myers has served up a ridiculous seven homers in 19.2 innings over three starts so far this season. He has an ugly career mark against Florida (6-10, 5.58) and the Marlins’ top hitters all own him (especially Dan Uggla — .344, three homers, nine RBI in 32 AB), so the Marlins odds are a tasty catch tonight.

Online betting pick: Marlins -134
