Rockies at Nationals, 7:05 ET Outfielder Carlos Gonzalez(notes) is having one of the hottest stretches in Rockies history and it can't be pinned on playing at Coors Field. One away from tying the club record, Gonzalez has hit a home run in four straight games — all on the road — to help the Rox maintain their lead in the NL wild card race and make the Dodgers feel itchy in the West. Gonzalez, who came from Oakland in the Matt Holliday(notes) deal, can tie Larry Walker and Dante Bichette if he homers in his fifth straight tonight. The 23-year-old, who has six homers in his past eight games overall, hit six homers in his first 130 major league games, Elias notes.
Marlins at Astros, 8:05 ET With Josh Johnson(notes) on the bump for the Fish and their odd-but-impressive streak of collecting at least 10 hits in 15 straight games on the line, fans have plenty of reason to tune in. Florida's hit streak is the longest since the 1937 St. Louis Browns (who are now the Orioles). The 1929 Giants also had a 15-game streak of at least 10 hits. Magic Wandy Rodriguez could shut them down, or he could allow 15 hits; you don't know with him.
Cubs at Dodgers, 10:10 ET Both teams need to start a winning streak, though the Dodgers still have the NL's best record so their desperation hasn't reached Cubs level yet. Tom Gorzelanny(notes) vs. Jeff Weaver(notes) in a reclamation project bowl.
