The main reason has been because of prolonged struggles by the rotation and bullpen. The Blue Jays went into their series finale against the Red Sox having surrendered at least seven runs in their past four games.
"We're going to get better as a pitching staff, I can guarantee you that," Blue Jays starter Brandon Morrow said. "The offense is doing a great job. They're coming in every day giving us a chance to win, playing great defense. ... They're doing a great job, we have to step it up and be a lot more consistent throwing strikes."
Toronto's staff entered Sunday ranked 12th in the American League with a 4.60 ERA and second with 108 walks. The recent issues have been evenly split between the starters and bullpen as Sergio Santos, Steve Delabar and J.A. Happ combined to set a franchise record with eight walks in an inning April 17. Morrow came within one walk of another franchise mark with eight walks Saturday afternoon.
The struggles also meant the Blue Jays starters ranked third from the bottom in the AL with 127 2/3 innings. That's forced Toronto to carry eight relievers as the starting staff has frequently struggled to pitch late into games and have recorded six-plus innings just 10 times in 24 games.
Even though the problems have been relatively easy to pin down, the Blue Jays aren't about to publicly start pointing fingers. Catcher Dioner Navarro gets to see both sides of the issue, but doesn't think there's any added pressure on the offense.
"We play 162 games, we're going to have to score, sometimes, a lot of runs, sometimes just one run only," Navarro said. "We have what it takes, we have to keep working hard, keep battling our butts off and things are going to change. I think our starting pitching has to do a much better job and our offense has to do a much better job. We have to score more runs than the other team and that's the bottom line."
