The Chicago Cubs will open the 2014 regular season at Pittsburgh and Chris Rusin is doing his best to be a part of their rotation. Rusin lowered his ERA to 2.85 in a tough 3-1 loss to the Pirates in which he allowed only four hits in seven innings while walking none. Rusin set a franchise record for the longest scoreless streak on the road by a rookie left-hander by extending his scoreless streak to 22 1/3 innings. It’s also the longest streak by a rookie left-hander since Neal Heaton of Cleveland threw 23 scoreless innings in 1983. “We’ll cross those bridges when we get to it” manager Dale Sveum said of Rusin’s chances in 2014. “He’s definitely put himself into a position to have every opportunity to make the rotation.” Rusin (2-4) who has made 11 starts continues to strengthen his credentials. He allowed two runs to a Pittsburgh team that was batting 23 points higher against left-handed hitters (.266) than right-handers (.243). “It was probably to me his most impressive outing against a lineup that has numbers against left-handers that’s impressive” Sveum said. As for his status in 2014 “I don’t think about it” Rusin said. Nor was he aware of his scoreless streak on the road that ended in the fourth inning on consecutive two-out hits from Marlon Byrd and Pedro Alvarez and wiped out a 1-0 Cubs lead.
