It's been a variety of factors. In April, the bullpen was pretty good, but the offense couldn't score in the late innings. Since May 1st, the offense has been great at scoring in the late innings, but the bullpen was awful during May. In June now, it looks like the bullpen is coming back- Howry's last 6 outings-6 1/3 IP, 4 H, 0 R, 6 K/1BB Wuertz's last 5-5 IP, 4 H, 1 R, 2 K/1BB Ohman's last 11-6 2/3 IP, 7 H, 2 R, 11K/2BB Marmol's last 11 outings-12 IP, 7 H, 2 R, 13K/4BB Dempster's last 10 outings-9 1/3 IP, 7H, 3 R, 7K/5BB Even Eyre has been slightly better lately (only 2 runs in his last 5 innings and 5 in his last 13 1/3 innings-not good, but better than April Eyre). Those top 5 together have been very, very good the last couple of weeks. If that continues at all, the Cubs record in 1 run games should improve.
