Crucial stretch: The Pirates enter Monday's game a half-game behind the Brewers in the National League Central, but if they are to stay in the race, the next 13 games will be huge. Pittsburgh has three against Cincinnati and three more at home against St. Louis before hitting the road for four in Atlanta and three more in Philadelphia. The Pirates are 11-17 against teams with winning records and 34-23 against teams with losing records, including a 9-3 mark against the Astros. Pittsburgh is 5-1 against Cincinnati heading into Monday night's game. The Reds are one of those teams with a losing record, but they are the defending champs in the division and are just 3.5 games back of the lead. Reds at Pirates, 7:05 p.m. ET (Follow live)
Diamond debut: Twins left-hander Scott Diamond will make his big league debut in the second game of a double header with Cleveland. Diamond is 4-8 with a 4.70 ERA in 17 starts for Triple-A Rochester this season. The Twins fell six games behind the Indians earlier in the day thanks to Asdrubal Cabrera's three-run homer in the third and seven shutout innings from David Huff. The Twins have two more games against the Indians this week before welcoming Detroit for four in a crucial stretch. Fausto Carmona (4-10, 5.78 ERA) will be activated from the disabled list before the game. Carmona injured his right quad when he tripped over first base in Cincinnati on July 2 but only missed one start thanks to the All-Star break. Indians at Twins, 8:10 p.m. ET (Follow live)
You want it, you got it: The Dodgers re-shuffled their rotation after the break to make sure Chad Billingsley would face the Giants. Billingsley is 3-1 with a 1.32 ERA in his last four starts before the break. In his career, the right-hander is 7-4 with a 3.01 ERA, but 1-1 with a 5.59 ERA in three starts against the Giants this season. He goes against San Francisco's Ryan Vogelsong (6-1, 2.17 ERA), who hasn't faced the Dodgers this season.
