Something has to give: Pittsburgh's Paul Maholm and Cleveland's Carlos Carrasco enter Saturday's matchup with scoreless innings streaks -- 15 1/3 for Carrasco and 13 for Maholm. Maholm hasn't allowed a run in three of his last four starts, including seven scoreless against the Mets on Monday and a shutout against the Cubs on May 28. Carrasco has been a good omen for the Indians during a rough streak, winning his last two starts as the team has struggled. He's won five of his last six starts, allowing two runs or fewer in four of those starts. Pirates at Indians, 7:05 p.m. ET (Follow live here)
Haren ready to hit: Much of the time when interleague play comes around, the thought of American League pitchers getting their chance at the plate is a joke. Maybe not so much for the Angels, as Dan Haren takes the mound -- and his spot in the lineup -- on Saturday at Citi Field in New York. When Haren was traded from the Diamondbacks to the A's last season, he was hitting .364/.375/.527 -- good for an OPS+ of 136, including a homer in 57 plate appearances. Oh, and he's also 6-4 with a 2.54 ERA this season. Haren's gone at least six innings in all of his starts, but has been burned by poor run support. Since improving to 4-0 on April 17, Haren has allowed two rearmed runs or fewer (going at least 6 2/3 innings each time) five times with just an 0-1 record to show for it. That's something Mets starter Mike Pelfrey can identify with. He's allowed two or fewer earned runs in four of his last six starts, going 0-1 in those games.

Rubby vs. Wandy: While most will remember Rubby De La Rosa and Wandy Rodriguez for their unusual first names, the two add up for a pretty strong pitching matchup. Rodriguez, the Astros' lefty, came off the disabled list on Monday to pitch six scoreless innings, allowing just two hits and four walks in a victory against Atlanta. The Dodgers rookie right-hander left his last outing after five innings with a forearm cramp, but still picked up the victory over the Rockies. In two starts, De La Rosa is 2-0 with a 3.60 ERA, striking out 10 and walking eight in 10 innings, while allowing seven hits and four earned runs.
