Prior to his scoreless outings on both May 3 and May 4, Chicago Cubs right-hander Koji Uehara showed signs of weakness when used in back-to-back games. Twice in April, he was roughed up by opponents, leaving some to question his durability at age 42.
On April 15, the Japan native tossed a scoreless frame against the Pirates, striking out one. The next day, Joe Maddon went to Uehara again only to get a drastically different result. Failing to record an out, the right-hander issued a pair of walks and two hits – culminating in a pair of runs.
